MODEL 172N
Steep slips should be avoided with flap settings greater than 20
°
due to a
slight tendency for the elevator to oscillate under certain combinations of
airspeed, sideslip angle, and center of gravity loadings.
NOTE
Carburetor heat should be applied prior to any significant
reduction or closing of the throttle.
Actual touchdown should be made with power-off and on the main
wheels first to reduce the landing speed and subsequent need for braking
the landing roll. The nose wheel is lowered to the runway gently after the
speed has diminished to avoid unnecessary nose gear loads. This proce
dure is especially important in rough or soft field landings.
SHORT FIELD LANDING
For a short field landing in smooth air conditions, make an approach at
the minimum recommended airspeed with full flaps using enough power
to control the glide path. (Slightly higher approach speeds should be used
under turbulent air conditions.) After all approach obstacles are cleared,
progressively reduce power and maintain the approach speed by lowering
the nose of the airplane. Touchdown should be made with power off and on
the main wheels first. Immediately after touchdown, lower the nose wheel
and apply heavy braking as required. For maximum brake effectiveness,
retract the flaps, hold the control wheel full back, and apply maximum
brake pressure without sliding the tires.
CROSSWIND LANDING
When landing in a strong crosswind, use the minimum flap setting
required for the field length. If flap settings greater than 20
°
are used in
sideslips with full rudder defl�ction, some elevator oscillation may be felt
at normal approach speeds. However, this does not affect control of the
airplane. Although the crab or combination method of drift correction may
be used, the wing-low method gives the best control. After touchdown, hold
a straight course with the steerable nose wheel and occasional braking if
necessary.
The maximum allowable crosswind velocity is dependent upon pilot
capability as well as aircraft limitations. With average pilot technique,
direct crosswinds of 15 knots can be handled with safety.
BALKED LANDING
In a balked landing (go-around) climb, reduce the flap setting to 20
°
immediately after full power is applied. If obstacles must be cleared during
4-20
