EMERGENCY
PROCEDURES
CESSNA
MODEL
172R
I
At the
landing
flare
(round-out),
the
nose
down
moment
resulting
from
power
reduction
is
an
adverse
factor
and the
airplane
may
land
on
the
nose
wheel.
Consequently,
at
flare,
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.
EMERGENCY
OPERATION
IN
CLOUDS

Vacuum
System Failure)
If
both the
vacuum
pumps
fail

on
the
turn

if
he
inadvertently
flies
into clouds.
If
an
autopilot
is
installed,
it
too
may
be
affected. Refer
to
Section
9,
Supplements,
for
additional details
concerning
autopilot operation.
The
following
instructions
assume
that
only
the
electrically
powered
turn
coordinator is
operative,
and
that the
pilot
is
not
completely
proficient
in
instrument
flying.
EXECUTING
A
