- high yaw rate, nose to the right - Engine noise level increase - Tachometer needles desynchronization on EPM - Rotorspeed decreasing and "low NR"
Power failure - hover below 8 feet
Use left pedal (counter yawing) -Raise collective slowly -Once landed, lower collective
Power failure during take off
- left pedal - level helicopter - <30kts; do no lower collective - >30kts; slightly pitch up while lowering collective - Approach ground, raise collective - Use pedal to minimize ground drift
You have lost tail rotor thrust during forward flight and a suitable landing site is not available. What can you do?
The vertical fin may permit limited controlled flight at low power settings and airspeeds above 70 KIAS; however, prior to reducing airspeed, re-enter full autorotation
Other in flight Power Failures
- Lower collective and maintain full down - Speed between 30-50kts (meestal dus snelheid eruithalen, pitch up slightly) - Select landing aerea - Monitor NR (rotor rpm) - Consider engine restart - At 60 feet slightly pull cyclic to raise nose
