NORMAL PROCEDURES
CESSNA
MODEL 172R
NOTE
If disorientation precludes a visual determination of the
direction
of rotation,
the symbolic airplane in the
turn
coordinator
may be referred
to
for
this information.
Variations in basic airplane rigging or in weight and balance due
to
installed equipment or right
seat
occupancy can cause
differences in behavior,
particularly in extended spins. These
differences
are
normal and will result in variations
in
the spin
characteristics and in the spiraling tendencies for spins of
more
than
2 turns.
However, the
recovery technique should always be used
and will result in the
most
expeditious recovery from any spin.
Intentional spins with flaps extended
are prohibited, since the
high speeds which may
occur
during
recovery are potentially
damaging
to
the flap/wing structure.
LANDING
NORMAL LANDING
Normal landing
approaches can be made with power on or
power
off with any flap setting desired. Surface
winds and air turbulence
are usually the primary factors in determining the most
comfortable
approach speeds. 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.
Actual touchdown should be
made with power off
and on the
main wheels first to
reduce the landing speed and subsequent need
for braking in the landing roll. The
nose wheel is lowered to the
runway
gently after the speed has diminished to
avoid unnecessary
nose gear loads. This procedure is especially important in rough or
soft field landings.
