Forced Landings; Landing Without Elevator Control - Cessna 172R Pilot Operating Handbook

CESSNA
SECTION 3
MODEL 172R
EMERGENCY PROCEDURES
FORCED LANDINGS
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. Transmit Mayday message on 121.5 MHz giving location
and intentions and squawk 7700.
Before attempting an "off airport" landing with engine power
available, one should fly over the landing area at a safe but low
altitude to inspect the terrain for obstructions and
surface
conditions, proceeding
as discussed under the
Precautionary
Landing With Engine 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. Avoid
a landing flare because of difficulty in judging height over a water
surface. The checklist assumes the availability of power to make a
precautionary water landing. If power is not available, use of the
airspeeds noted with minimum flap extension will provide a more
favorable attitude for a power off ditching.
In a forced landing situation, do not turn off the avionics power
and master switches
until
a landing
is
assured.
Premature
deactivation of the switches will disable the airplane electrical
systems.
Before performing a forced landing, especially in remote and
mountainous areas, activate the ELT transmitter by positioning the
cockpit-mounted switch to
the ON position.
For
complete
information on ELT operation, refer to Section 9, Supplements.
LANDING WITHOUT ELEVATOR CONTROL
Trim for horizontal flight (with an airspeed of approximately 65
KIAS 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.
