Power Failure Above 500 Ft AGL
1 2 3 4 5 6 7 8 |
1. Lower collective immediately to maintain RPM and enter normal auto-rotation
2. Establish a steady glide at approximately 65 KIAS 3. Adjust collective to keep RPM in green arc or apply full down collective if light weight prevents attaining above 97% 4. Select landing spot, and if altitude permits, maneuver so landing will be into wind 5. A restart may be attempted at pilot's discretion if sufficient time is available. 6. If unable to restart, turn off unnecessary switches and shut off fuel 7. At about 40 feet AGL, begin cyclic flare to reduce rate of descent and forward speed 8. At about 8 feet AGL, apply forward cyclic to level ship and raise collective just before touchdown to cushion landing. Touch down in level attitude with nose straight ahead |

Power Failure between 8 ft and 500 ft AGL
1. 2. 3. 4. 5. 6. 7. 8. |
1. Takeoff operation should be conducted per the height-velocity diagram in Section 5
2.If power failure occurs, lower collective immediately to maintain rotor RPM 3. Adjust collective to keep RPM in green arc or apply full down collective if light weight prevents attaining above 97% 4. Maintain airspeed until ground is approached, 5.then begin cyclic flare to reduce rate of descent and forward speed 6. At about 8 AGL apply forward cyclic to level ship and 7. raise collective just before touchdown to cushion landing. 8. Touchdown with skids level and nose straight ahead. |
