  15. What are the procedures for a engine failure?
    • Reduce Collective IMMEDIATELY
    • Adjust pitch to maintain 90% to 107% rotor RPM
    • Reduce airspeed to 60 mph to 70 mph
    • At low altitude flare to loose excessive airspeed
    • Apply collective to decrease forward airspeed and cushion landing
  16. What to do if you get a low rotor RPM light?
    • Rotor RPM is below normal
    • Reduce collective and check throttle is full open
  17. What to do if you get a Battery Hot Light?
    • Battery case temp has reached 60'C or higher
    • Land as soon as possible
    • After landing DO NOT use battery for engine restart
    • Service or replace battery
  18. What to do if you get a Battery Temp Light?
    • Battery temperature has reached 54.4'C or higher
    • Turn battery switch off until it cools
    • Then turn battery switch on
  19. What to do is you get a Transmission Chip Light?
    • Metal particles in transmission oil
    • Land as soon as possible
  20. What to do if you get a T/R Chip light?
    • Metal particles in tail rotor gear box
    • Land as soon as possible
  21. What to do if you get a Engine Chip Light?
    • Metallic particles in Engine Oil
    • Land as soon as possible
  22. What to do if you get a Engine Out Light
    • Engine power failre
    • Reduce collective and preform autorotation landing
  23. What does a Low Fuel Light Mean?
    • Approximately 20 gal of fuel remaining
    • Land as soon as Practical
