.
,The stall characteristics
are conventional
and aural warning
is
provided by a stall warring
horn which .sou~ds between 5 and 10
knots above the stall in all configurations .
. Power offstall
speeds at "maximum weight forboth
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 bec'arefuliy
considered
to assu're
a'
safe' flight.
No spins
should be 'atiempted
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 172S.

The cabin should be clean and all loose equipment (including the
microphone and rear seat belts) should be stowed or secured. For a
solo f1ight.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 erough
altitude that recoveries are completed 4000 feet or
• more above ground level. Ai .least 1000 feet of altitude loss"should
be allowed for a1-turn
spin and recovery, while 'a 6-!urn spin and
recovery may require somewhat more than twice that amount. For
exam'ple, 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,co'mpleted
well above the minimum
"1500 feet above grourid
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.
