TAKEOFF-NORMAL
1)
Throttle

2)
Engine Instruments
- CHECK normal indications
3)
Attitude
- Hold slight back elevator
4)
Lift-Off
- 35 – 40 MPH
5)
Climb
- 40 - 50 MPH
Takeoff characteristics are conventional. It is recommended that the nose be raised with the
elevator slightly during the takeoff roll. Transition into flight with a minimum of control input.
During crosswind conditions, place the control stick into the wind and assume a level attitude
with the elevator to prevent drifting or premature lift-off. The Ascender will turn into wind
during the take-off roll, so commencing the take-off at the down wind side of the runway is
recommended.
TAKEOFF OVER OBSTACLE
During an obstacle takeoff, use the normal takeoff procedures with the following exceptions:
1)
Lift-Off
- 30 MPH
2)
Climb
- 35 MPH (best angle of climb, for prolonged climb to obstacle)
