Engine Power Loss; Approach And Landing - Piper cherokee WARRIOR Pilots Operating Manual

CHEROKEE WARRIOR
Intentional spins are prohibited. Maneuvering at speeds in excess of 124 mph must be
luvoided in order to prevent overstressing the airframe.
ENGINE POWER LOSS
The most common cause of engine power loss is mismanagement of fuel. Therefore, the
flrst step to take after engrne power loss is to move the fuel selector to the tank not being used.
This rvill often restore power even if there is no apparent reason for the engine to stop on the
tank being used.
If changing to another tank does not restore power:
I .
Check fuel pressure - if electric fuel pump is off, turn it ON.
2.
Push mixture control to full RICH.
3.
Check ignition switch. Turn to best operating magneto - LEFT, RIGHT, or BOTH.
APPROACH AND LANDING
Before landing check list:
l.
Seat backs - erect
2.
Safety belts/harness - fastened
3.
Fuel - on proper tank
4.
Electric fuel pump - on
5.
Mixture - full rich

The airplane should be trimmed to an approach speed of about 80MPH with flaps up. The
flaps can be lowered at speeds up tol l5 MPH*, if desired, and the approach speed reduced 3
MPH for each additional notch of flaps. Carburetor heat should not be applied unless there is an
indication of carburetor icing, since the use of carburetor heat causes a reduction of power
which could be critical should a goaround be necessary. Full throttle operation with carburetor
heat on is likely to cause detonation.
The amount of flap used during landings and the speed of the airplane at contact with the
runway should be varied according to the landing surface, wind conditions, 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. Reduce the airspeed during
flareout and contact the ground at close to stalling speed. After ground contact hold the nose
wheel off as long as possible. As the airplane slows down, drop the nose and apply the brakes.
There will be less chance of skidding the tires if the flaps are retracted before applying the
brakes. Braking is most effective when back pressure is applied to the control wheel, putting
most of the airplane 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.
