Stopping Engine - Piper Dakota PA-28-236 Pilot Operating Handbook

PIPER AIRCRAFT CORPORATION
PA-28-236, DAKOTA
Turn ON the electric fuel pump, and turn OFF the air conditioner. The
mixture should be set in the full RICH position and the propeller at full
INCREASE rpm to facilitate ample power for an emergency go-around.
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 airplane should be trimmed to a final approach speed of 72 KIAS
with flaps extended. The flaps can be lowered at speeds up to 102 KIAS, if
desired.
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, carburetor heat
OFF, and electric fuel pump ON. Reduce the speed during the flareout
and contact the ground close to the stalling speed (50 to 65 KIAS). 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 then 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 flaps must be placed in the UP position
for the flap step to support weight. Passengers
should be cautioned accordingly.
