4.21 BEFORE TAKEOFF
All aspects of each particular takeoff should be considered prior to executing the takeoff procedure.
Turn “ON” the master switch and check and set all of the flight instruments as required. Check the
fuel selector to make sure it is on the proper tank (fullest). Turn “ON” the electric fuel pump and check
the engine gauges. The carburetor heat should be in the “OFF” position.
All seat backs should be erect and the seat belts and shoulder harness fastened. Fasten the seat belts
snugly around the empty seats.
NOTE
If the fixed shoulder harness (non-inertia reel type) is installed, it
must be connected to the seat belt and adjusted to allow proper
accessibility to all controls including fuel selector, flaps, trim, etc.,
while maintaining adequate restraint for the occupant.
If the inertia reel type shoulder harness is installed, a pull test of its
locking restraint feature should be performed.
The mixture should be set and the primer checked to insure that it is locked.
NOTE
The mixture should be set FULL RICH except a minimum
amount of leaning is permitted for smooth engine operation when
taking off at high elevation.
Exercise and set the flaps and trim tab. Insure proper flight control movement and response. All doors
should be properly secured and latched. On air conditioned models, the air conditioner must be “OFF” to
insure normal takeoff performance.
4.23 TAKEOFF
The normal takeoff technique is conventional. The tab should be set slightly aft of neutral, with the
exact setting determined by the loading of the airplane. Allow the airplane to accelerate to 45 to 55 KIAS
depending on the weight of the aircraft and ease back on the control wheel to rotate to climb attitude.
Premature raising of the nose or raising it to an excessive angle will result in a delayed takeoff. After
takeoff, let the airplane accelerate to the desired climb speed by lowering the nose slightly.
Takeoffs are normally made with flaps up; however, for short field takeoffs and for takeoffs under
difficult conditions such as deep grass or a soft surface, total distances can be reduced appreciably by
lowering the flaps to 25° and rotating at lower airspeed.
A short field takeoff with an obstacle clearance is accomplished by first lowering the flaps to 25°.
Apply full power before brake release and accelerate to 52 KIAS and rotate. Maintain 52 KIAS until
