SECTION 4
NORMAL PROCEDURES
CESSNA
MODEL 172R
STALLS
The stall characteristics are conventional and aural warning is
provided by a stall warning
horn which sounds between 5 and
10
knots above
the
stall in all configurations.
Power
off
stall speeds
at
maximum weight for both forward and
aft C.G. positions are presented in Section 5.
SPINS
Intentional spins
are approved
when the airplane is operated in
the utility category. Spins with baggage loadings
or
occupied
rear
seat(s)
are
not approved.
However, before attempting
to
perform spins several items
should
be carefully considered
to
assure
a
safe flight. No spins
should be attempted without first having received dual instruction
both in spin entries and spin recoveries from
a
qualified instructor
who is familiar with the spin characteristics of the Cessna 172R.
The cabin should be clean and all loose equipment (including the
microphone and rear
seat
belts) should
be
stowed
or
secured.
For a
solo flight in which spins will be conducted, the copilot's
seat
belt
and shoulder harness
should
also be secured. Care
should be
taken
to
ensure
that the pilot
can easily reach the flight controls and
produce maximum control travels.
It is
recommended
that,
where feasible, entries be accomplished
at
high enough altitude that recoveries are completed 4000 feet or
more above ground level. At least 1000 feet of altitude loss should
be allowed for
a
1-turn
spin and recovery, while a 6-turn spin and
recovery may
require somewhat
more
than twice that
amount.
For
example, the
recommended
entry
altitude for a
6-turn
spin would be
6000 feet above
ground level. In any
case,
entries should be
planned
so
that
recoveries are completed well above the minimum
1500 feet above ground level required by FAR
91.303.
Another
reason for using high altitudes for practicing spins is that
a
greater
field of view is provided which will assist
in maintaining pilot
orientation.
