Ch 9 (Emergency Procedures) Flashcards
Land Without Delay
The term LAND WITHOUT DELAY is defined as a landing in which the primary consideration is continued control of the aircraft and survival of the occupants. It is meant to be more urgent than Land As Soon As Possible. The situation may not permit the aircrew to continue to maneuver the aircraft to a suitable landing area (e.g., open field). If maneuvering to an open area is not practical, then the crew must make the decision to land in an area that will have the least amount of negative impact on crew survivability. (e.g. Over dense forest, select an area with the smallest trees, in a mountainous area, choose an area with the least amount of slope).
Land as Soon as Possible
The term LAND AS SOON AS POSSIBLE is defined as landing at the nearest suitable landing area (e.g., open field) without delay. The primary consideration is to ensure the survival of occupants.
Land As Soon As Practicable
The term LAND AS SOON AS PRACTICABLE is defined as landing at a suitable landing area. The primary consideration is the urgency of the emergency.
Autorotate
The termAUTOROTATEis defined as adjusting the flight controls as necessary to establish an autorotational descent and landing.

Loss of Tail Rotor Thrust at Low Airspeed/Hover
- Collective – Reduce (compromise between rate of turn and rate of descent).
- Wing Stores Jettison – (As appropriate).

If NP (affected engine) is below NR (indicating the clutch is disengaged):
- EMER ENG SHUTDOWN (affected engine).
- LAND AS SOON AS PRACTICABLE.
If NP (affected engine) does not drop below NR (indicating the clutch has failed to disengage):
- LAND AS SOON AS POSSIBLE.
- EMER ENG(S) SHUTDOWN (both engines simultaneously).
Main Transmission Input Drive Clutch Failure – On Ground
On Ground (with indications that a clutch has failed to engage):
