Purpose: To demonstrate a takeoff when a hover cannot be sustained due to high density altitude or high gross weight.
|Cyclic:||Pitch Attitude/Airspeed; Ground Track|
|Collective:||Altitude; Rate of Climb|
|Pedals||Heading (Below 50 ft AGL); Trim (Above 50 ft AGL)|
- From a stabilized 3 foot hover, note the hover power.
- Set the helicopter down on the surface, perform pre-takeoff checks, and then clear the area.
- Takeoff power will be 1″-2″ MAP less than power required to hover.
- Begin by increasing the collective to get the helicopter light on the skids.
- Neutralize any aircraft movement before continuing.
- Slowly increase collective and apply forward cyclic to get the helicopter sliding forward on the surface.
- Maintain heading with pedals and ground track with cyclic.
- Continue to slowly increase collective until the modified takeoff power is achieved.
- At the onset of effective translational lift, apply slight back pressure on the cyclic and lift the helicopter to 3-5 feet.
- Continue to accelerate remaining at 3-5 feet until the airspeed of 40-45 KIAS is obtained and then allow the aircraft to climb.
- At an altitude of 50 feet AGL, adjust the manifold pressure to normal takeoff power.
Note: Do not attempt this maneuver if you do not have sufficient power to hover. If the helicopter cannot hover, its performance is unpredictable and maneuver should be aborted.
