Emergency Procedures Flashcards

1
Q

What does LAND AS SOON AS POSSIBLE mean?

A

Land without delay at the nearest suitable area (i.e., open field) at which a safe approach and landing is reasonably assured.

Q

What does LAND AS SOON AS PRACTICAL mean?

A

The landing site and duration of the flight are at the discretion of the pilot. Extended flight beyond the nearest approved landing area is not recommended.

Q

What is the fault and remedy for an ENG OUT light (audio if functional)?

A
  • Engine power failure (N1 less than 55%)
  • Reduce pitch immediately to autorotate
  • If ample altitude remains investigate failure, attempt engine relight

Q

What is the fault and remedy for a LITTER DOOR OPEN light?

A
  • Left rear cabin passenger/litter door not securely latched
  • Close door securely before flight
  • If light illuminates during flight, land as soon as practical

Q

What is the fault and remedy for a GEN FAIL light?

A
  • Failure of generator
  • Check GEN FIELD and RESET circuit breakers IN
  • Perform generator reset operation
  • GEN switch OFF if service is not restored
  • Land as soon as practical

Q

What could cause an engine fire during start or shutdown?

A

May be caused by an overloading of fuel in the combustion chamber and a delayed ignition of the fuel, resulting in high TOT and flame emanating from the tailpipe

Q

What is the procedure for an engine fire during flight?

A
  1. Throttle - Close
  2. Immediately enter autorotation
  3. Fuel - OFF
  4. Battery switch - OFF
  5. Generator switch - OFF
  6. Execute normal autorotation descent and landing

NOTE: Do not restart engine until corrective maintenance has been performed

Q

How and why would you ventilate the cabin if there was smoke?

A
  • Ventilation of the cabin to protect the pilot and cabin occupants from the effects of toxic fumes, smoke, etc., shall be performed as follows:
    1. Cabin vent - PULL OPEN
    2. Open cabin windows for max. ventilation

Q

Where should rotor rpm be near the end of autorotation?

A

Rotor RPM maintained at the high end of the operating range will provide maximum rotor energy to accomplish the landing

Q

What is the airspeed for Minimum Rate of descent and for Maximum Glide Distance during autorotation?

Q

What is the maximum airspeed during autorotation?

A
  • Maximum airspeed for steady autorotation is 115 MPH IAS
  • Autorotation above this speed results in high rates of descent and low rotor speeds

Q

What is the procedure for Autorotation?

A
  1. Collective pitch control - Adjust as required to maintain rotor rpm, 90 to 107%
  2. Cyclic control - Adjust to obtain desired autorotative airspeed for existing conditions. Normal autorotation airspeed is 70 MPH
  3. If ample altitude remains, attempt Engine Air start
  4. Cyclic - Flare to reduce airspeed and descent rate
  5. Collective - Increase to cushion touch down

Q

What are the symptoms of a fuel control and/or governor failure?

A
  • Engine fuel control and/or governor failure will be apparent by a change of power or RPM

Q

What is the procedure for an Engine fuel control and/or governor failure?

A
  1. Control power with throttle if engine over speeds
    - Maintain rpm with collective pitch if engine under speeds
  2. Establish autorotative glide if power is low or if engine must be shutdown
  3. Prepare for power-off landing
17
Q

What is the procedure for a complete loss of tail rotor thrust?

A
  • Reduce throttle to flight idle and immediately enter autorotation and maintain a minimum airspeed of 60 MPH
  • The large ventral fin may permit controlled flight at low power levels and sufficient airspeed
  • Touch down shall be accomplished with the throttle in the full closed position
18
Q

What is the procedure for a fixed pitch failure (Pitch change slider, control failure)?

A
  • Power - Adjust as required to minimize excessive yawing
  • Airspeed - Adjust to determine best velocity to minimize excessive yawing
  • Perform autorotation descent and landing
