7.19 CRUISE
Normal cruising is performed between 55% and 75% power. The engine rpm and
corresponding fuel consumption for various altitudes can be determined by the
data contained in Section 5. The data in Section 5 shows the increased range and
improved fuel economy that is obtainable when operating at lower power settings
and higher altitudes. The use of lower power settings and the selection of cruise
altitudes on the basis of the most favorable wind conditions are significant factors
that should be considered on every trip to reduce fuel consumption. To deter-
mine the most reliable and most favorable altitude and power setting for a given
trip, refer to Section 5, Figure 5-5.
7.20 STALLS
The stall characteristics are conventional for the flaps-up and flaps-down configu-
rations. Slight elevator buffeting may occur just before the stall with flaps down.
The stall warning horn (if installed) produces a steady signal 5 to 10 knots before
the actual stall is reached and remains on until the airplane attitude is changed.
Stall speeds for various combinations of flap setting and bank angle are summa-
rized in Section 5.
7.21 SPINS
WARNING
Intentional spins are prohibited.
In case an inadvertent spin occurs, the following recovery technique should be
used:
1. VERIFY THAT THROTTLE IS IN THE IDLE POSITION AND AILERONS ARE
NEUTRAL
2. APPLY AND HOLD FULL RUDDER OPPOSITE TO THE DIRECTION OF ROTA-
TION
3. JUST AFTER THE RUDDER REACHES THE STOP, MOVE ELEVATOR CONTROL
BRISKLY FORWARD FAR ENOUGH TO BREAK THE STALL
4. HOLD THIS CONTROL INPUT UNTIL ROTATION STOPS
5. AS ROTATION STOPS, NEUTRALIZE RUDDER AND MAKE A SMOOTH RE-
COVERY FROM THE RESULTING DIVE.
Variations in basic airplane rigging or in weight and balance due to installed equip-
ment or cockpit occupancy can cause differences in behavior, particularly in ex-
tended spins. However the above recovery procedure should always be used and
will result in the most expeditious recovery from any spin.
