Ditching - Guimbal CABRI G2 Flight Manual

Hélicoptères Guimbal
CABRI G2
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 :
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.
3-4
Anticipate that sink rate will not stop until final
collective raise.
