Introduction
This Flight Manual is designed as an operating guide for the pilot. It
includes material required to be furnished to the pilot by EASA CS 27 and
Part 21. It also contains supplementary data supplied by the helicopter
manufacturer.
This manual is intended to give the pilot the best possible information
and to help him find the best answer to most operational situation. However,
it cannot replace pilot’s appreciation of each particular situation. Pilot must
maintain adequate ground and flight instruction, and good proficiency in the
type of helicopter.
To achieve the required level of safety, the helicopter pilot-in-command
must be familiar with this manual’s content, with other safety-related
available information, and with all the regulation covering aircraft operation
that are relevant in the country of operation. He is responsible for
determining that the helicopter is safe for flight, and for operating it in
respect to this manual and above information.
The helicopter’s owner is responsible for maintaining the aircraft in
approved airworthy condition and for maintaining this manual in a current
status in accordance with the list of current pages.

Indicated power on MLI
The Multiple Limits Indicator displays the engine power status, based on engine
manifold absolute pressure. The indicator (pointer and digits) displays power
delivered by the engine in terms of margin to the first of these limits whose
relative positions vary with engine inlet air temperature and altitude:
•
Power (PWR) limit: it corresponds to the engine
5-minute power of
119 kW (160 hp). The red radial PWR mark shows that the limit could be
exceeded if the pilot requires too much power.
•
Yellow arc: it corresponds to the range of power above max cont. power
(108 kW - 145 hp) that can be used for 5 minutes, up to 30 kt IAS.
o After 1 minute in the yellow arc, a countdown indicator appears,
displaying time remaining in minutes, surrounded by an increasing arc
of ring figuring the time elapsed up to 5 minutes. The pilot should
lower the power below the yellow arc before the count-down has
elapsed or before exceeding 30 kt IAS.
o After
5 minutes in the yellow arc, it becomes red, showing
maximum duration has elapsed.
o Limitations to use the yellow arc:
Limited to 5 minutes and a maximum airspeed of 30 kt IAS,
AVGAS only. Using alternate grades (refer to 2-6 Fuel) forbids
the use of the yellow arc.
•
Throttle (FLO) limit: it corresponds to full throttle power. FLO limit
corresponds to the maximum power that the engine can deliver. The red
FLO arc warns the pilot that the limit cannot mechanically be exceeded in
order to help him anticipate: the consequence of increasing collective
when FLO limit is reached is the main rotor speed drop.
The part of the yellow arc which extends above FLO limit appears in red,
showing it cannot be used.
The pilot should control the power demand to avoid exceeding PWR limit or 5
minute duration, or avoid entering yellow zone when 30 kt IAS is exceeded.
Exceedance of the limit may result in accelerated engine and transmission
performance degradation, but does not require any emergency procedure. Any
degradation should be identified through normal maintenance in a timely
manner.

EMERGENCY PROCEDURES
The information in section 3, emergency procedures, is approved by EASA.
Introduction
The following emergency procedures describe the actions the pilot must
take, relative to the various possible failures that can occur.
However, depending on the many variable external environments, such as
the type of terrain flown over, the pilot may have to adapt to the situation
according to his experience.
To help the pilot in his decision process, three recommendations are used :
• LAND IMMEDIATELY
• LAND AS SOON AS POSSIBLE
Emergency conditions are urgent and require landing at the nearest landing
site at which a safe landing can be made.
• CONTINUE FLIGHT
Continue flight as planned. Repair at the destination according to
maintenance manual.
Note: Immediate action that the pilot shall take, or main parameters
are written in bold characters.
In addition to procedures, Warnings, Cautions and Notes can highlight
specific points according to the following definitions:
Warning: An operating procedure, practice, etc., which, if not correctly
followed, could result in personal injury to, or death of, personnel.
Caution: An operating procedure, practice, etc., which, if not correctly
followed, could result in damage to, or destruction of, equipment.
Note: An operating procedure, condition, etc., which is essential to
highlight.

EMERGENCY PROCEDURES
Power failures
General
Engine failure can be detected by :
• Yaw acceleration, nose to the right,
• Engine noise level decreases,
• Tachometer needles desynchronization on the EPM
(engine
decreases)
• OIL P warning on the EPM and OIL P red light coming ON.
• Plasma beeper,
• Rotor speed decreasing and “low NR” horn.
Caution : A slow decay in engine power, caused by carburetor icing
or air filter clogging, is compensated by the governor and can
be overlooked by the pilot.
The MLI indication will not change while in PWR mode, but
will rapidly shift to FLO mode, then increase to 100%.
Primary transmission failure can be detected by :
• High yaw rate, nose to the right,
• Engine noise level increases,
• Tachometer needles desynchronization on the EPM
(engine
increases). Eventual engine overspeed only if the governor is OFF
• Rotor speed decreasing and “low NR” horn.
In case of a primary transmission failure, apply following power failure
actions. Roll off the twist grip as soon as possible.
Warning :
Safe landing may not be possible if the power failure occurs within
the “unsafe” zone of the H/V diagram (refer to section 5).
Operation inside this zone should be avoided.

EMERGENCY PROCEDURES
Power failure - hover below 8 feet AGL
The helicopter will normally exhibit little or no tendency to depart in pitch
or roll, hence requiring little correction :
1. Use left pedal input to counter yawing to the right,
2. Cushion landing by raising collective, until high pitch stop if
necessary,
3. Once landed, lower the collective.
Power failure during take-off
Take-off acceleration is the most critical situation for a power failure to
occur, requiring moderate and rapid pilot reaction :
1. Use left pedal input to counter yawing to the right,
2. Use aft cyclic to level the helicopter,
3. Before having reached 30 kt IAS, do not lower the collective,
4. If IAS is above
30 kt IAS, slightly pitch up while slightly
lowering the collective, if needed, to prevent climbing,
5. When approaching the ground, raise the collective to cushion
contact,
6. Use pedals to minimize ground drift,
7. Once stopped, lower the collective.
Other in-flight power failures
All cases :
1. Lower the collective immediately and maintain full down,
2. Use pedals to control yaw,
3. Maintain IAS between
30 and
50 kt IAS
(50 kt IAS
recommended),
4. Select landing area and manoeuvre to land into the wind,
5. Adjust collective to centre NR in green arc,
6. When the landing is ensured, consider engine restarting if
enough time is available. Refer to page 3-5.
7. At about 60 feet AGL, apply aft cyclic to raise the helicopter
nose smoothly and continuously. Below
50 kt IAS, this
manoeuvre will not stop sink rate.
8. As ground closes-on, apply forward cyclic to level the helicopter
while raising the collective to stop sink rate.
9. Use pedals to minimize ground drift,
10. Once stopped, lower the collective.
Note : Average manoeuvre requires about 200 to 300 m (650 to 1000
feet) free of high obstacle.

Hélicoptères Guimbal
SECTION 3
CABRI G2
EMERGENCY PROCEDURES
Note : During an emergency autorotation, always control airspeed
carefully.
Increasing airspeed above 50 kt IAS makes the landing easier, but
requires a longer landing area.
Confined landing area :
When landing spot is confined, maintain IAS to
30 kt IAS in
descent. Landing spot can be estimated by looking between the pilot
pedals.
Caution : Anticipate that sink rate will not stop until final
collective raise.
Failure above 2000 feet AGL :
It may be practicable to increase gliding distance to reach a better
landing area.
• Best glide ratio is obtained at airspeed approximately
80 kt IAS (no wind). Increase airspeed with high headwind,
• Recommended NR is mid-yellow arc (480 RPM),
• At about 300 feet AGL, reduce IAS between 30 and 50 kt
IAS (50 kt IAS recommended), check NR in green arc and
refer to the above procedure.
Airspeed and rotor speed adjustments will reduce the gliding
distance. Expect a PRACTICAL glide ratio between 2:1 and 3:1 or
0.7 to 1 nautical mile at 2000 feet AGL.
Ditching
1. Apply same procedures as for landing,
2. Head equally between the wind and wave direction,
3. Open doors,
4. Reduce forward and vertical speed to minimum possible before
contact with water,
5. Keep collective up after contact, to help rotor deceleration.

In-flight engine restart
Attempt engine restart only when the autorotation is stabilized on the
trajectory to an appropriate landing area, and sufficient time is available.
If successful, power recovery can take only a few seconds.
1. Stabilize autorotation,
2. Check boost pump ON, fuel valve OPEN,
3. Check mixture full forward (RICH),
4. Check both ignition switches ON, upward,
5. Apply about 50 % throttle (90° twist grip),
6. Press starter button.
Note 1 : Governor may be kept engaged or not.
Note 2 : Do not worry for engine very fast acceleration. There is no risk
of overtorque at re-synchronization. Be prepared to yawing to
the left if power recovers.
Note 3 : In absence of perceivable sound, the STARTER light gives a
visual clue that the starter is actually energized.

Doors-lock and anti-theft
To unlock / lock the doors, press the corresponding button on the key-ring
radio transmitter. Check the flashing strobe light confirmation.
If the transmitter is ineffective, check the “Auxiliaries” breaker inside the
battery box.
Unlocking / locking the doors also enables / disables the engine starter, if
active (refer to page 7-19).
Note : The starter is enabled when the rotor is turning above 400 RPM,
whatever the antitheft state.
Before flight
The pilot should be familiar with helicopter limitations detailed in Section 2
of this manual.
The pilot should have checked weight and balance. Refer to Section 2 and
Section 6 of this manual.
The pilot should check helicopter performance according to Section 5 of this
manual.
The pilot should carry out a pre-flight check before each flight.
The use of automotive gasoline without specific fuel gauge leads to fuel
gage error and time remaining to starvation display error. Refer to page
4-15 for fuel management with automotive gasoline.
Daily or Pre-flight checks
The following check must be carried out before each flight.
However, if the helicopter is operated by a single pilot, or in an organization
where checks are done by a qualified mechanic, this check may be carried-
out daily, before the first flight of the day.
In this case, an inter-flight check should be done between each flight (refer
to page 4-7).
Preliminaries
Remove airframe covers, Pitot and static plugs, blade tie downs and
exhaust plug.
In cold weather, remove all frost, ice or snow.
Purpose of the following inspection is to :
-
Visually check the helicopter general condition,
-
Detect leakage indications,
-
Detect aluminum fretting marks : dark powder marks,
-
Detect steel fretting marks : black or brown marks/residues,
-
Detect overheating marks (color changing),
-
Detect damages (impacts, scratches, cracks, frictions,

Warning :
• The clutch may have stayed engaged, or engage unexpectedly,
allowing the rotor to turn at starter engagement.
• The blades can be very dangerous particularly at low speed, and
with gusts or wind. They are very heavy and flexible.
˛ Never engage the starter while the area is not completely clear of
people and foreign objects in a 6 meter (20 foot) radius. The
blades may turn unexpectedly.
˛ The pilot must not leave the cockpit as long as the engine or the
rotor turns. He must wait complete stop.
˛ Strictly forbid all people presence in the rotor area - 6 meter
(20 foot) radius, while the engine is running or the rotor is turning,
unless controlled by the pilot in command as follows :
˛ To allow a person enter or exit the cabin or rotor area - 6 meter
(20 foot) radius, the pilot must :
1. Make sure the wind is less than 20 kt,
2. Hold the collective down,
3. Hold the cyclic slightly aft,
4. Maintain the RPM steady in the yellow - green arc,
5. Watch the person in lateral sector and allow by a head sign.
Do not move the cyclic while the person has started
moving towards the helicopter.
It is the pilot’s responsibility to make sure that take-off and landing area is
clear from all people that could be endangered, and that all people
approaching the helicopter are well aware of above warnings, and
briefed to :
1. Stay clear 6 meters (20 feet) of the helicopter,
2. Watch the pilot and wait his sign before moving into the

Note 2: Cold weather starting:
After a failed starting attempt, oil pressure red light may stay off a
while because of viscous cold oil. Pilot should crank again within 80
seconds of previous cranking. Otherwise, cranking will be inhibited
until oil pressure decreases in the red zone.
When starting an engine soaked at very cold temperature (-20 to
-10°C/-4 to 14°F), apply not less than 5 fuel injections and avoid high
throttle settings. Refer to SL10-001 for detailed recommendations.
Note 3: Depending on belt condition and temperature, the rotor may slightly
engage from engine start. In this case, engage clutch to avoid
prolonged belt slippage.
Note 4: As the rotor begins to spin, a cyclic stick rotation may occur. Center
the stick smoothly.
Note 5: ALT light may flicker at idle. Check ALT lights goes off above

Take-off procedure
On clear flat area
1. Apply collective pitch progressively to stabilize hover at 2 feet skid height.
2. Adjust cyclic trim.
3. Check engine parameters in green arcs and warning / caution lights OFF.
4. Apply slight forward cyclic to accelerate at a constant height.
5. At 45 kt IAS, rotate to reach and maintain 50 kt IAS.
6. Once climb is stabilized, adjust power as needed. Rate of climb should not
exceed 500 ft/min below 100 feet in order to ease piloting in case of an
engine failure.
7. Follow take-off profile shown on Height-Velocity diagram shown page 5-3 :

Note 1 : Take-off is possible without increasing power in case of a very slow
acceleration on hard surface.
Note 2 : Take-off run may be shortened, by raising slightly the collective to
compensate for height loss, if power margin enables it.
On other surface (confined area or surrounded by obstacles)
Refer to HOGE performance page 5-4.

Flight time management
The EPM has two features to ease flight management :
• A fuel flow computer, giving different data described page 7-15,
• A flight time counter, displaying the real flight time to be logged,
described page 7-14.
The flight time display is frozen at rotor shutdown, until next start-up, and is
stored in the EPM flight log page.
The average fuel flow during ongoing flight is stored in the EPM flight log
page.
One flight is counted from rotor start-up, to rotor shutdown.
Caution : The fuel gage and fuel flow indication have a lower accuracy than
their display.
Always perform a cautious fuel planning, and take adequate
reserve for the kind of operation.
Always trust the LOW FUEL warning light as per page 3-15.

Fuel quantity management with alternate fuel
The use of automotive gasoline without specific fuel gauge (MOD 12-051 or
corresponding Service Bulletin) leads to fuel gage error and time remaining
to starvation display error. In this case :
- for flight preparation, take into account actual fuel quantity rather than
gage indication,
- When loading more than 150 liters of automotive gasoline, switch Master
ON and check that gage is displaying quantity up to
179 liters
(47 ¼ U.S.gal). Above this value, the EPM considers it an error and displays
XXX. In this case, this indication is not a no-go.
- in flight, correct reading using the chart below. Mixing with AVGAS leads
to intermediate error readings
- As per emergency procedure section, LOW FUEL light, which is
independent of fuel gage, should be considered as a warning and lead to
immediate landing.

NORMAL PROCEDURES
Training
Caution : The Cabri G2 has a very capable rotor, giving her comparatively
permissive autorotation characteristics. This allows efficient
training and practice, from different situations and using different
piloting techniques.
Following procedures are given as guidelines and should be
followed for best safety.
However, pilot and instructor should keep in mind that power
failure training is a very demanding practice, requiring a high
level of awareness, good health and personal condition, and
aircraft in perfect airworthy state.
Power failure practice must be limited to the strict needs of
instruction and maintaining good proficiency. Never practice
autorotation as a show.
Pilot must stay familiar with Height-velocity diagram page 5-3 together with
procedures described in Section 3 to follow them in case of an actual
failure.
Autorotation must only be practiced over an area that would minimize
hazards associated with an actual engine failure.
Smooth and hard surface should be preferred to practice running landings.
In order to familiarize with Cabri G2 landing attitude, practice powered
running landings before autorotation training.
Caution : Before attempting running landings, check thoroughly carbide
wear shoes. An unexpected drift during a running landing is a
clue to a carbide shoe failure. Always check in case of doubt.
Rapid throttle chops should not be used to practice autorotation.
During autorotation training, try to keep the helicopter skids level
at touchdown, to avoid unpleasant pitch-down and bouncing.
If the ground is not smooth and if the rotor speed is too low when
the helicopter touches the ground, a pitch oscillation can happen,
leading to an uncomfortable landing. In that case, the pilot has to
keep the cyclic control in the neutral position in order to prevent
induced oscillations.

NORMAL PROCEDURES
Power failure in hover in ground effect practice
1. Roll-off throttle frankly until on its stop,
2. Counteract yaw motion by applying left pedal,
3. Increase collective as ground approaches, to smooth landing,
4. Push collective down once landed.
Note 1 : If the helicopter is light, it may bounce after a first touchdown.
Note 2 : The Cabri G2 has no natural tendency to depart in roll or pitch after
failure. No systematic corrective cyclic action is needed.
A slight forward motion at impact is recommended for better
control.
Note 3 : For a forgiving practice, respect a maximum of 5 feet height.
Note 4 : Avoid practice at maximum gross weight.
Autorotation practice
1.
Lower collective full down,
2.
Counteract yaw motion by applying left pedal,
3.
Roll-off throttle through its spring ramp to its stop,
4.
Maintain IAS between
30 and
50 kt IAS
(50 kt IAS
recommended) by controlling longitudinal cyclic,
5.
Slightly increase collective if required to keep rotor speed in the
green arc,
6.
At about 60 feet AGL, apply aft cyclic to raise the helicopter nose
smoothly and continuously.
7.
As ground closes-on, apply forward cyclic to level the helicopter
while raising the collective to stop sink rate.
• With a 50 kt IAS approach, landing requires a longer distance
but is easier to manage. Little action is required on the
collective control since the flare will stop the sink rate.
• A 30 kt IAS approach needs smaller cleared area for landing
but is more difficult to manage.
8.
Use pedals to minimize ground drift,
9.
Once stopped, lower the collective.
Note :
When autorotation is stabilized with collective full down, the rotor
speed should stay in the authorized range, whatever the weight
and the altitude in flight envelope.
Caution : If airspeed drops below 30 kt IAS, push frankly the cyclic forward
to recover airspeed.

Aborting autorotation practice
If power recovery is decided during autorotation :
1. Roll-in throttle until governor engages,
2. Gradually raise collective pitch to stop autorotation and descent,
3. Control yaw during power recovery with pedals.
Note : Do not worry for very fast engine acceleration. There is no risk of
overtorque at re-synchronization. Be prepared to yawing to the left
when power recovers.
EPM failure
A flight instructor should make the student familiar with the NR lights :
1. Select an appropriate flight phase with little workload,
2. Mask the EPM screen with a paper or the night vision filter,
3. Switch NR to “Backup”,
4. Control the flight in order not to exceed the power limit : moderate
the cruise speed and practice cautious landing within this flight
take-off conditions.

Airframe
General
The Cabri G2 airframe is composed of three sections :
• The main fuselage, including cabin, central structure, luggage
and fuel compartments. It is all made of composite sandwich.
• The engine section, isolated between a front and an aft
firewalls. It is made of the steel truss engine mount, and
composite cowlings.
• The aft structure, a composite shell combining the tail boom,
the fins, and the tail rotor shroud, with the horizontal stabilizer.
Two composite cabin doors enable passenger / pilot access.
One composite door enables external access to the luggage
compartment.
Landing gear
The main landing gear is composed of two tubular bows, and two skids.
It is attached to the fuselage by soft elastomeric mounts, giving
adequate frequency tuning against ground resonance. There is no
damper.
The landing skids are protected against abrasion by a set of carbide
wear shoes.
Seating
The cabin features two high-energy absorbing, stroking-seats, improving
occupants protection in case of a crash.
Note : The left seat pan can be removed to carry large cabin luggage.
Specific optional brackets are available to secure them. A cap is
provided to cover cyclic root, as copilot controls are removed.

Dynamic systems
Main rotor
The Cabri G2 main rotor is a three-bladed, fully articulated, soft-in plane
rotor.
The rotor hub is forged from aluminum alloy, and attached to the
stainless-steel mast, by a large splines and cones attachment, with a
thrust nut. The hub is belted with a tough fiberglass winding, which
increases its tolerance to damage.
The blades are made of carbon and fiberglass-reinforced composite,
with a large internal steel tip weight, and lead balance weight, to
increase rotor inertia.
Their fork attachment is directly connected to an elastomeric, spherical
thrust bearing which ensures pitch, flap, and lead-lag motions.
They have a two-section, thick stainless steel leading edge cap which
protects them against erosion due to sand, dust and precipitations.
Each blade is linked to the rotor hub via an elastomeric lead-lag damper,
made of a single cylindrical layer of special rubber.
The blades are restrained in flapping-down, by a reciprocal droop-stop
ring, guided in the rotor hub.
Tail rotor
The tail rotor is shrouded in the vertical fin.
It has seven reinforced-plastic-injected blades. Pitch change is permitted
by their stainless steel laminated tension-torsion pack.
The tail rotor hub is directly mounted on, and driven by the tail gearbox,
and its pitch control mechanism is part of the gearbox.
The tail gearbox is rigidly supported inside the shroud, by a three-tube
mount. The front tube houses the tail rotor driving shaft.

• aft to the tail rotor transmission.
The main gearbox contains a splash-lubricated spiral bevel-gear set
which transmits power to the rotor mast. It is equipped with a filler plug /
breather, a sight gage and a self-closing magnetic chip detector.
The main gearbox upper and lower casings act as a tough central
structure, rigidly bolted in the middle of the fuselage structure.

SYSTEMS DESCRIPTIONS
The steel tail rotor driveshaft runs inside the tail cone, on three ball
bearings.
A disc rotor brake is installed on the fore portion of tail driveshaft. The
brake jaws are actuated through a cable control, from an overhead
control quadrant.
The tail gearbox contains a splash-lubricated spiral bevel-gear set which
transmits power to the tail rotor.
It also incorporates the tail rotor pitch control mechanism.
It is equipped with a filler plug / breather, a sight gage and a self-closing
magnetic chip detector.
Flight controls
The Cabri G2 has dual flight controls which includes cyclic stick,
collective stick and pedals.
Left controls are totally removable, without tools, if needed. They can be
stowed in the cabin luggage compartment.
Cyclic and collective controls actuate main rotor blade pitch through
push-pull rods, bellcranks and the swashplate.
Yaw control is transmitted from the pedals to the tail rotor by a long
flexible push-pull control.
The collective stick grip is divided into one fixed part and one twist grip
to enable sensitive throttle control, and to allow governor motion.
The collective stick is equipped with a friction mechanism, which is
controlled by the pilot, without releasing his hands from the controls.
The cyclic sticks have no friction mechanism, but a dual-axis electric
trim, allowing to completely release the static forces in flight.
This trim system is controlled either by the pilot or the copilot, through a
circuit which gives priority to the one who activates it first.
Rotor brake
A rotor brake allows the pilot to stop quickly the rotor after flight. This
rotor brake is mounted on the tail rotor driveshaft. It is actuated by a
cable connected to a pull handle located above the pilot (yellow handle).
It is equipped with a switch used to trigger BRAKE light and prevent
clutching when the brake is applied or seized.

Engine installation
Engine
The engine is a four-cylinder, direct-drive, carbureted gasoline engine.
It is installed in the central compartment, suspended through elastomeric
vibration mounts.
It moves slightly to control the main transmission belt tension for clutch
engagement / disengagement.
Clutch
The clutch tension actuator is fed by engine oil pressure through a four-
way distributor, controlled by the CLUTCH switch.
This system is frozen in case the electrical power is shutdown.
A non-return valve maintains the pressure in case of engine stoppage,
or oil pressure loss.
A gas spring maintains the engine disengaged during prolonged stop.
The CLUTCH light lights OFF when the pressure of the oil feeding the
distributor is above 3.6 bar. In the clutched position, it means that the
belt is tensioned. In the declutched position, it means that the clutch
cylinder is on its declutched stop.
Air induction
The engine air intake is located inside the main gearbox compartment,
on the right side. It is fed in fresh air, by the front inlet above the cabin.
A wire screen prevents foreign object ingestion.
The air is ducted down the firewall, to an air filter box, behind the
carburetor.
This air box includes an electrically-actuated butterfly valve, which
controls the carburetor heating, and the air filter.
Both cold and hot air are filtered.
An air intake temperature probe, located inside the air filter, sends the
carburetor inlet temperature to the EPM.
Ignition system
The engine has a dual-plug, mixed ignition system comprising :
• One magneto with constant timing,
• One solid-state electronic capacitor-discharge system, with
variable timing.
The electronic system is direct-fed by the battery through a dedicated
circuit breaker, located on the cabin breaker panel.

Carburetor heat
The Cabri is equipped with a two-mode carburetor heat :
•
Normal automatic mode (switch on AUTO) : the EPM monitors
carburetor temperature and controls the heating valve to keep it
outside the yellow zone,
•
Manual / test mode (switch on HOT or COLD) : The pilot
manually controls the valve, overriding the EPM.
Indicator
A four-brick indicator informs the pilot of the
amount of carburetor heating actually measured
at carburetor inlet.
Full carburetor heat is divided in four steps, each
represented by one brick.
Note 1 : During ground run or at low power setting, with a warm
engine, T. induction may be biased by carburetor body heat radiation.
For this reason, a brick can appear whereas the heating valve is closed.
Note 2 : - In automatic mode, the EPM gradually opens the valve as
needed to maintain Tcarb out of the yellow zone. The amount of heating
is given by the indicator.
- In manual mode, the pilot can either completely open (HOT) or
completely close (COLD) the valve. When on HOT, all four bricks might
not be lighted, depending on environmental conditions.
Note 3 : Conditions conducive to carburetor icing are :
High humidity, low temperature,
Operating near water,
Moderate to low power setting.
Note 4 : In manual operation, switching from one position to the other
should be done smoothly, with a small pause on Auto.

BARC
BARC (Fuel and rotor alarm device). It is designed as an alternate mean in
case of EPM failure.
It should be preferred in case of doubt.
When the MASTER is switched ON, the BARC conducts a testing sequence
for caution / warning lights on the instrument panel, and the rotor speed
horn.
In order to reinitiate the testing sequence, the MASTER should be switched-
off during 45 seconds (make also sure that NR switch is on MAIN).
In case of an electrical bus failure, the BARC can be switched to a direct
battery backup supply.

Other equipment
Pitot - Static system
The Pitot tube is non-heated. It is located under the helicopter belly.
The static port is located just aft of it.
Engine governor
An electric engine governor helps the pilot control the engine speed.
When engaged, it acts on the twist grip to control throttle.
Once switched-on, the governor engages above 2000 RPM (NR =
400 RPM), and self-disengages below.
The pilot can disengage it by two ways :
• Using the GOV switch located on the tip of the collective stick.
The GOV OFF light then comes on,
• Forcing the twist-grip to NM = 2000 RPM, for an engine failure
simulation.
At any time, a friction clutch in the governor motor enables the pilot to
overtake it by acting on the twist grip. The pilot can easily disengage the
governor while overtaking its action.

Doors lock / Anti-theft
Remote doors lock is provided by a small radio transmitter. It uses a
radio security-code to control the cabin doors locks, and enable/disable
the engine starter.
Note : The starter is enabled when the “Rotor in flying mode” signal is
active (see page7-17), whatever the antitheft state.
The antitheft can be disabled (starter enabled) if not needed :
• Peel-off the CODE label on the left side of the central console,
below the instrument console. Locate the small 8-switch line,
• Key the 8-bit helicopter individual security code : 1 is up, 0 is
down
• To activate the antitheft back, just scramble the switches.
If the transmitter is not operative, following procedure permits to fly :
• Locate the backup key lock on the right firewall, above the
Gascolator,
• Open the luggage door, using the backup key,
• From the luggage door, reach the right cabin door lock,
• From the right seat, open the left door lock,
• Use above procedure to disable the anti-theft.
Note : The remote door locking circuit has a very small standby current
drain. However, when storing the helicopter for more than a month, pull
the AUXILIARIES battery breaker, inside the battery shelter.
Lights
The helicopter is equipped with :
• a strobe light atop vertical fin,
• navigation lights on fuselage sides,
• a landing light in the nose.
Refer to Section 9 Night VFR for optional cabin lights.

Cabin and amenities
Luggage compartments
A 200 liter luggage compartment is provided in the right side of the
fuselage.
It can accept two standard trolley cabin suitcases.
It is accessible from the outside, through a hinged door, and from the
cabin through a small access hole, limited to soft objects.
Another luggage compartment is provided in the cabin, to stow the
removable passenger controls, and some small cabin luggage : camera,
drink, etc.
It is accessible from a small door in front of the passenger pedals. It
features a cigarette-lighter socket for auxiliary power output.
Soft luggage like clothes can be stowed under the stroking seats.
Ventilation and heating
Each door has an adjustable fresh air vent.
For a better ventilation at lower airspeeds, and particularly in a hover,
doors must be partially opened during flight using the cord strap.
A cabin heater / defogger is provided. It takes its air from the engine
cooling blower.
The control knob is located between the two seats, on the central
console.
In case of fire, shutting the heater off prevents fire from crossing the
firewall through heating system.

HANDLING AND SERVICING
Parking and tie-down
Parking the helicopter on a soft surface may cause it to tilt back due to aft
center of gravity when empty. In case of doubt, for long time parking, place
a hard piece of wood beneath the skid aft tips before removing the wheels.
Tie-down should only be done by straps attaching the landing gear. Starting
S/N 1045 (MOD 12-010), a specific tie down ring is located on the rear bow
fitting.
Avoid leaving the helicopter exposed to direct sunlight without shielding the
canopy with external cover or internal survival blanket.
Tie the blades with appropriate straps in case of strong wind or high gusts.
Keep the straps loose to avoid stressing the blades.
Dual controls removal and installation
Dual controls are designed for quick and easy plug-and-play:
-
Collective stick is secured by a locking sleeve and pedals by a self-
locking pin:
Removal: action the locks to remove the controls.
Installation: install the controls until they are secured. For the collective,
maintain the locking sleeve pushed while plugging the stick. Rotate the
stick until the sleeve locks.
Caution : make sure that the controls are locked after they are put in place.
-
Cyclic control removal:
1. remove the lock pin and push the backup lock to remove the pin,
2. unscrew the ring at the root of the cyclic base, unplug the electrical
connector and remove the cyclic stick,
3. unscrew the rod end and screw the protection cap to prevent
interference in case luggage are placed on the left cabin compartment
(left cabin luggage kit).
-
Cyclic control installation:
1. Remove the cyclic base root cap if installed and screw the rod end
to contact.
2. Put the cyclic stick in place, parallel to pilot stick, and screw the ring

3. Align the rod end and install the pin, head pointing rearward. Ensure
the head is locked by its backup lock. Install the lock pin.
4. Plug the electrical connector.
Doors removal and installation
Starting S/N 1066 or retrofitted with SB14-005, doors have self-locking
hinges, requiring no pin:
Door removal:
1. Open the door,
2. Remove the small circular locking clip from gas spring attachment
on the fuselage side. Snap the rod end off,
3. Open the door passed the normal opening to free the locking
tongue. Slide off.
Caution: Always put your hand between the door and the frame next to the
lower hinge to prevent scratching the windshield post paint.
Door installation:
1. Position the door wide open,
2. Engage the lower pin which is longer, then engage the upper pin,
3. Snap the gas spring rod end on its sphere, and install the small
locking pin in the rod end.
For initial design, without self-locking hinges, the procedure is as follows:
Door removal:
1. Open the door,
2. Remove the small circular locking clip from gas spring attachment
on the fuselage side. Snap the rod end off,
3. Remove the two hinges lock pins, and save the washers,
4. Slide the door off.
Door installation:
1. Install the door, and check the plastic bushings are in place,
2. Install one washer and one lock pin on each hinge.
Note: The lower hinge has its plastic bushing inverted, to take the upward
thrust from the gas spring. The washer is then important.
3. Snap the gas spring rod end on its sphere, and install the small
locking pin in the rod end.
Caution: Never install the gas spring without the hinge pins: the gas spring
exerts an upward force that would eject the door.
The gas spring should be installed in the right direction: rod facing
inside/forward, body on the door side.
