The mixture control should be kept in full “RICH” position to insure maximum acceleration if it
should be necessary to open the throttle again. Carburetor heat should not be applied unless there is an
indication of carburetor icing, since the use of carburetor heat causes a reduction in power which may be
critical in case of a go-around. Full throttle operation with carburetor heat on can cause detonation.
The amount of flap used during landings and the speed of the aircraft at contact with the runway
should be varied according to the landing surface and conditions of wind and airplane loading. It is
generally good practice to contact the ground at the minimum possible safe speed consistent with existing
conditions.
Normally, the best technique for short and slow landings is to use full flap and enough power to
maintain the desired airspeed and approach flight path. Mixture should be full “RICH,” fuel on the fullest
tank, and electric fuel pump “ON.” Reduce the speed during the flareout and contact the ground close to
the stalling speed. After ground contact hold the nose wheel off as long as possible. As the airplane slows
down, gently lower the nose and apply the brakes. Braking is most effective when flaps are raised and back
pressure is applied to the control wheel, putting most of the aircraft weight on the main wheels. In high
wind conditions, particularly in strong crosswinds, it may be desirable to approach the ground at higher
than normal speeds with partial or no flaps.
4.31 STOPPING ENGINE
At the pilot’s discretion, the flaps should be raised and the electric fuel pump turned “OFF.” The air
conditioner and radios should be turned “OFF,” and the engine stopped by disengaging the friction
adjustment lever and pulling the mixture control back to idle cut-off. The throttle should be left full aft to
avoid engine vibration while stopping. Then the magneto and master switches must be turned “OFF.”
NOTE
When alternate fuels are used, the engine should be run up to 1200
RPM for one minute prior to shutdown to clean out any unburned
fuel.
NOTE
The flaps must be placed in the “UP” position for the flap step to
support weight. Passengers should be cautioned accordingly.
4.33 PARKING
If necessary, the airplane should be moved on the ground with the aid of the nose wheel tow bar
provided with each airplane and secured behind the rear seats. The aileron and stabilator controls should be
secured by looping the safety belt through the control wheel and pulling it snug. The flaps are locked when
in the “UP” position and should be left retracted.
Tie downs can be secured to rings provided under each wing and to the tail skid. The rudder is held in
position by its connections to the nose wheel steering and normally does not have to be secured.
