CESSNA SECTION 4
MODEL 152 NORMAL PROCEDURES

THIS DATA APPLICABLE ONLY TO AIRPLANES
WITH LYCOMING O-235-L2C ENGINE.

AIRPLANES WITH ENGINE MODIFIED TO O-235-NCS,
REFER TO DATA IN SECTION 9 SUPLEMENT
CROSSWIND TAKEOFF
Takeoffs into strong crosswinds normally are performed with the minimum flap setting
necessary for the field length, to minimize the drift angle immediately after takeoff. With the
ailerons partially deflected into the wind, the airplane is accelerated to a speed slightly higher
than normal, and then pulled off abruptly to prevent possible settling back to the runway while
drifting. When clear of the ground, make a coordinated turn into the wind to correct for drift.
ENROUTE CLIMB
Normal climbs are performed with flaps up and full throttle and at speeds 5 to 10 knots higher
than best rate-of-climb speeds for the best combination of performance, visibility and engine
cooling. The mixture should be full rich below 3000 feet and may be leaned above 3000 feet
for smoother operation or to obtain maximum RPM. For maximum rate of climb, use the best
rate-of-climb speeds shown in the Rate Of Climb chart in Section 5. If an obstruction dictates
the use of a steep climb angle, the best angle-of-climb speed should be used with flaps up and
maximum power. Climbs at speeds lower than the best rate-of-climb speed should be of short
duration to improve engine cooling.
CRUISE
Normal cruising is performed between 55% and 75% power. The engine RPM and
corresponding fuel consumption for various altitudes can be determined by using your Cessna
Power Computer or the data in Section 5.
NOTE
Cruising should be done at 65% to 75% power until a total of 50
hours has accumulated or oil consumption has stabilized. This is to
ensure proper seating of the rings and is applicable to new engines,
and engines in service following cylinder replacement or top
overhaul of one or more cylinders.
The data in Section 5 shows the increased range and improved fuel economy that is
obtainable when operating at lower power settings. The use of lower power settings and the
selection of cruise altitude on the basis of the most favorable wind conditions are significant
factors that should be considered on every trip to reduce fuel consumption.
