LOW SPEED SYSTEMS CHECK (CONT)
*4. Stall speed, stall warning, and stall
characteristics (gear and flaps
down. power on) - Check as fol-
a. Gear - DN, below 178 KIAS.
b. Flaps - Down (100%) below
c. Propeller levers - Set 2000
d. Power levers - Set 75% torque.
e. Trim aircraft to trim speed as
shown in figure 2.
f. Airspeed - Reduce by one knot/
second until aircraft stalls.
*g. Airspeed (at warning and at
stall) - Record (KIAS).
h. Roll must be controllable with-
in 15 degrees left or right.
*5. Flap operation - Check as follows:
a. Airspeed - Reduce to 196 KIAS
b. Flaps - APPROACH. Check
flaps for freedom and smooth-
ness of operation and for exces-
sive aircraft roll.
c. Airspeed - Reduce to 151 KIAS
d. Flaps - 100%. Check flaps for
freedom and smoothness of op-
eration and for excessive air-
