  1. Land As Soon As Possible
    Executing a landing to the nearest suitable landing area.  (e.g., open field)  without delay

    The primary consideration is to assure the survival of the occupants.
  2. Land As Soon As Practicable
    Execute a landing to the nearest suitable airfield/ heliport.
  3. Autorotate  Definition
    The term autorotate is defined as adjusting the flight controls as necessary to establish an autorotational descent and landing.
  4. Autorotate
    • 1. Thrust Control-- Adjust as required to       
    •     maintain RRPM

    2. Pedals-- Adjust as required

    3. Cyclic-- Adjust as required
  5. Emergency Engine Shutdown  Definition
    Engine shutdown without delay.
  6. Emergency Engine Shutdown
    1. ENG COND Lever-- Stop

    2. Fire Pull Handle-- Pull (engine fire only)

    • 3. AGENT DISCH switch-- As requried
    •     (eng fire only)

    4. Perform single-engine failure procedure.
  7. Abort Start  Definition
    An engine shutdown to prevent PTIT from exceeding limits or whenever abnormal operation is indicated.
  8. Abort Start
    1.  ENG COND Lever-- Stop

    • 2.  ENG START switch-- MTR
    •     (if high PTIT is indicated)
  9. If a second engine start is to be attempted, how long, after N1 indicates zero should you wait before attempting start?
    15 seconds

    This will allow sufficient time for fuel to drain from the combustion chamber.
