CESSNA
MODEL 172R (180 HP)
STALLS
SECTION 4
NORMAL
PROCEDURES
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
(180 HP).
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.
