CESSNA SECTION 4
MODEL 152 NORMAL PROCEDURES
1 July 1978 4-18
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 91.71. 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.
The normal entry is made from a power-off stall. As the stall is approached, the elevator
control should be smoothly pulled to the full aft position. Just prior to reaching the stall "break",
rudder control in the desired direction of the spin rotation should be applied so that full rudder
deflection is reached almost simultaneously with reaching full aft elevator. A slightly greater
rate of deceleration than for normal stall entries or the use of partial power at the entry will
assure more consistent and positive entries to the spin. Both elevator and rudder controls
should be held full with the spin until the spin recovery is initiated. An inadvertent relaxation of
either of these controls could result in the development of a nose-down spiral.
NOTE
Careful attention should be taken to assure that the aileron control
is neutral during all phases of the spin since any aileron deflection
in the direction of the spin may alter the spin characteristics by
increasing the rotation rate and changing the pitch attitude.
For the purpose of training in spins and spin recoveries, a I to 2-turn spin is adequate and
should be used. Up to 2 turns, the spin will progress to a fairly rapid rate of rotation and a
steep attitude. Application of recovery controls will produce prompt recoveries of from 1/4 to
1/2 of a turn.
If the spin is continued beyond the 2 to 3-turn range, some change in character of the spin may
be noted. Rotation rates may vary and some additional sideslip may be felt. Normal
recoveries from such extended spins may take up to a full turn or more.
Regardless of how many turns the spin is held or how it is entered, the following recovery
technique should be used:
