The
presence of
fire
is noted through
smoke, smell,
and
heat
in the
cabin. It
is essential
that
the
source
of
the fire be prornptly identified
through
instrument readings, character of the
srnoke,
or other
indications,
since
the
action to be taken
differs
sornewhat in each case.

above
is
general
and pilot

deciding factor
for action
in
such an emergency.
LOSS OF OIL PRESSURE
Loss
of
oil pressure
may be either partial
or complete.
A partial
loss
of
oil pressure
usually
indicates
a malfunction in the oil pressure
regulating
system, and a
landing
should
be
made
as
soon as possible
to
investigate the
cause,
and
prevent
engine
damage.
A complete
loss of
oil
pressure indication
may
signify
oil
exhaustion
or
may
be
the result
of
a
faulty gauge. In
either
case,
proceed
toward
the
nearest airport, and be prepared for
a
forced
landing. If
the
problem
is not a
pressure
