Autorotation Landing
- Lower Collective (to maintain NR in normal operating range)
- Establish IAS 65 kts
- Twist Grip in IDLE position
- Maneuver the aircraft into the wind on final approach
- At 70 ft FLARE to a nose up attitude
- At 20-25 ft and constant attitude increase collective to reduce rate of descent and forward speed
- Apply forward cyclic before touchdown for slight nose up attitude <10*
- Adjust Pedals to cancel any side slip
- Increase collective to cushion touchdown
- Control ground run by adjusting cyclic, collective and pedals
- Once aircraft stopped > full low collective
- Apply rotor brake below 170 RPM
Relighting in Flight
According to available height (at least 1000ft to complete relighting) and cause of flame out:
- Engine starting selector > OFF position
- Fuel Pump > ON
- Engine starting selector > ON
The relighting sequence will then run automatically as soon as Ng 17%
- After relighting > Fuel pump OFF
Loss of Tailrotor Thrust
Hover IGE:
1. Twist grip > IDLE position
2. Increase collective to cushion touchdown
Hover OGE:
Simultaneously,
1. Reduce collective
2. Forward cyclic to gain airspeed
3. Maintain IAS 65 kts or higher
4. Adjust collective to obtain minimum sideslip
5. LAND AS SOON AS POSSIBLE > carry out autorotative landing on suitable landing area (during descent > twist grip to IDLE position)
In cruise flight:
1. Maintain IAS 65 kts or higher
2. Adjust collective to obtain minimum sideslip
3. LAND AS SOON AS POSSIBLE > carry out autorotative landing on suitable landing area (during descent > twist grip to IDLE position)
VEMD Screen Failures
Failure of one screen:
- Failed screen > OFF
- Read all available information on the other screen
- Information available using SCROLL button or button on collective lever
If top screen fails, torque and delta Ng off line. Comply with limitations.
Failure of both screens:
To avoid any power overlimit the max. authorized power will be power needed for level flight at 100 kts (-2 kts/1000 ft)
LAND AS SOON AS PRACTICABLE
Flight Control Hardover or Servojam
In IGE Hover, takeoff, final:
- LAND IMMEDIATELY
-after landing- - Hydraulic cut off switch (collective) > OFF
- Shut down
In flight:
- Set IAS to 40-60 kts
- Hydraulic cut off switch (collective) > OFF
- LAND AS SOON AS POSSIBLE
Abnormal Nf governing
- Abnormal low NR and Nf (Parameters aligned)
> FADEC governs Nf to a value that is significantly lower than usual.
> Caused by an erroneous collective anticipatory signal
> NR/Nf may decrease to 360 rpm before failure is detected by FADEC
> GOV light comes on
- Check engine parameters
- Check NR/Nf
- LAND AS SOON AS PRACTICABLE
