SECTION 3
EMERGENCY PROCEDURES
FORCED LANDINGS
CESSNA
MODEL 172N
If all attempts to restart the engine fail and a forced landing is
imminent, select a suitable field and prepare for the landing as discussed
under the Emergency Landing Without Engine Power checklist.
Before attempting an "off airport" landing with engine power availa
ble, one should fly over the landing area at a safe but low altitude to inspect
the terrain for obstructions and surface conditions, proceeding as dis
cussed under the Precautionary Landing With �ngine Power checklist.
Prepare for ditching by securing or jettisoning heavy objects located
in the baggage area and collect folded coats for protection of occupants'
face at touchdown. Transmit Mayday ·message on 121.5 MHz giving
location and intentions and squawk 7700 if a transponder is installed.
A void a landing flare because of difficulty in judging height over a water
surface.
LANDING WITHOUT ELEVATOR CONTROL
Trim for horizontal flight (with an airspeed of approximately 60 RIAS
and flaps set to 20
°
) by using throttle and elevator trim controls. Then do
not change the· elevator trim control setting; control the glide angle by
adjusting power exclusively.
At flareout, the nose-down moment resulting from power reduction is
an adverse factor and the airplane may hit on the nose wheel. Consequent
ly, at flareout, the elevator trim control should be adjusted toward the full
nose-up position and the power adjusted so that the airplane will rotate to
the horizontal attitude for touchdown. Close the throttle at touchdown.
FIRES
Although engine fires are extremely rare in flight, the steps of the
appropriate checklist should be followed if one is encountered. After
completion of this procedure. execute a forced landing. Do not attempt to
restart the engine.
The initial indication of an electrical fire is usually the odor of burning
insulation. The checklist for this problem should result in elimination of
the fire.
