Q

EMER ENG Shutdown

A
  • Engine shutdown without delay.
  • Engine shutdown in flight is usually not an immediate action item unless a fire exists.

  1. ENG COND Lever - STOP
  2. FIRE PULL handle - Pull as required
  3. FIRE PULL handle - Twist clockwise or counterclockwise as required (engine fire only)

Q

Autorotative Landing

A
  • Maintain speed at or above the minimum R/D airspeed in autorotation with cyclic.
  • 50-75 ft AGL, apply aft cyclic as necessary, not to exceed 20° nose-high, to initiate a smooth deceleration.
  • Maintain NR below 108% by adjusting thrust as necessary.
  • Do not allow NR to decay below 91% prior to touchdown.
  • At approximately 15 ft AGL, apply thrust to slow R/D.

Q

Dual Engine Failure - Low Altitude / Low Airspeed

A
  • When both engines fail at low altitude and low airspeed, sufficient altitude is not available to increase NR.
  • Establish the best autorotaional airpseed, jettison external cargo (if applicable), and decelerate effectively prior to touchdown.
  • Initial thrust control lever adjustment will vary from no reduction at 0 knots airpseed below 20 feet to full reduction at higher airpseeds and altitudes.
  • Attempt to maintain at least 96% NR.
