02 NORMAL TAKE-OFF
TAKE-OFF POWER SETTING
The standard take-off power setting is 48’ MAP/2700 RPM
SPEEDS
Take-off speed V1 = 83 kts IAS (is Vmca)
- Speed Relations
Vmca = 83kts IAS
Vr = 1,05* Vmca = 87 kts IAS
V2 = 1,1 * Vmca = 91 kts IAS
Operational Vyse/V2 is 90 kts
When lined up, compass heading and aircraft position should be checked for positive
runway identification.
Where obstacles or noise abatement require such, this procedure should be amended
accordingly.
A rolling take-off is recommended, except in limited runway length conditions.
When making a take-off from the brakes advance the throttles and just before reaching
take-off power release the brakes.
Pitch trim setting is normally 0 so the stick-forces at rotation vary with the CG.
To apply take-off power, advance the power levers slowly.
For all take-offs the landing lights shall be switched on unless weather conditions are such
that undue glare results.
During crosswind take-off the tendency for the upwind wing to lift should be counteracted
by decisive use of aileron during the take-off run, rotation and lift-off.
Directional control during take-off run must be maintained by rudder control and use off
differential power during the beginning of the take-off roll. Nosewheel should be straight
before power application.
During the take-off roll keep control column full aft until the nosewheel loses contact with
the runway, then gradually release back pressure on the control column so much that the
nose wheel will not touch the runway. (do not over rotate !!!)
During the take-off roll in this configuration the aircraft will fly itself off the runway.
Once airborne lower the nose and fly level in ground effect to 95 kts, than readjust pitch to
a climb attitude. And maintain airspeed of 95 kts.
