- TOT
- Torque

23
Q

Engine torque, TOT, N1 and N2/NR, suddenly increasing.
Possible right yaw

24
Q

  • N2/NR decaying.
  • Possible left yaw.
  • Possible low rotor warning indication.
26
Q

Emergency Procedures
Fuel Control or Power Turbine Governor Failure

27
Q

Emergency Procedures
Fuel Control or Power Turbine Governor Failure

A

N2 fluctuating: governor not maintaining pre-set speed (102-103%N2)

28
Q

Emergency Procedures
Fuel Control or Power Turbine Governor Failure
Turbine Governor Surge Procedures

A
  • Turning the start pump ON may allow the engine to operate smoothly. If operation of the engine returns to normal, it may be possible to fly to a favorable landing area, however do not disregard the need to land.
  • Beep N2 to maximum.
  • Control N2 manually with twistgrip (102% to 103% N2).

NOTE: This action takes the governor out of the system allowing the pilot manual control of the N2 and should eliminate the surge.

36
Q

What is One way lock failure?

A

The one way lock assembly is a self contained hydraulic unit that prevents aft feedback forces in the longitudinal cyclic control system.

37
Q

Emergency Procedures
One Way Lock Failure
Indications & Procedures

A

I - Aft feedback in the cyclic at high airspeed and/or during pull ups from high airspeed or higher than normal forces required to move the cyclic longitudinally.

P - Reduce airspeed to 100 KIAS or less.
- Limit cyclic movement to those movements required to safely fly the helicopter. Abnormal or extreme control inputs are not necessary.

38
Q

Emergency Procedures
Inoperative Trim
Conditions & Procedures

A

C - The trim motor fails to respond to application of the cyclic trim switch in one or more directions

P - Establish a safe flight condition that produces the least cyclic control force. Normally straight and level at the last trimmed airspeed.
- Actuate the trim switch thru all positions in an attempt to restore trim capability and determine the extent of trim failure. If restored, trim to a near neutral position and land as soon as practical avoiding further trimming.
- If trim failure is determined to be in all directions, and control of the helicopter can be maintained safely, check/reset TRIM circuit breaker.
- Land as soon as practical if unable to reestablish full cyclic trim control with the pilot’s cyclic.

39
Q

Emergency Procedures
Runaway Trim
Indications & Procedures

A

I - An uncommanded longitudinal or lateral cyclic trim actuation. The cyclic may move to a full travel position or some intermediate position resulting in cyclic forces up to the maximum. Uncommanded movement can occur after cyclic trim switch actuation or as a result of an electrical short.

P - Establish a safe flight condition that produces the least cyclic control force.
- Utilize left hand and legs, as necessary, to apply pressure against the cyclic stick to relieve the right hand loads and conserve strength for landing. Use collective friction to prevent unwanted collective movement and associated power change.
- Actuate the trim switch thru all positions, several times if necessary, as this will generally re-establish trimming capability. When restored, trim to a near neutral position and land as soon as practical avoiding further trimming.
- If trim runaway is to the full forward position, accomplish landing into the wind and do not hover downwind in winds in excess of 15 knots

40
Q

Ways to reduce forward & aft cyclic forces during a runaway trim.

A

Forward runaway - Maintain higher airspeeds
Aft runaway - Maintain slower airspeeds

41
Q

- If GEN OUT indicator remains ON or comes back ON, pull generator circuit breaker OUT and insure generator switch is in the ON position for the remainder of the flight.
- If GEN OUT indicator remains ON, reduce electrical load to a minimum.
- Land as soon as practical.
