AMPLIFIED EMERGENCY PROCEDURES
r-------NOTE------.....,
A complete knowledge of the procedures set forth
in
this
section
will
enable the pilot to cope
with
various
emergencies that can
be
encountered; however, this does
not diminish the fact that the primary responsibility of the
pilot
is to
maintain
control at
all
times. Good judgment
and
precise action are essential and can only
be
developed
through frequent practice of emergency
and
simulated
engine inoperative
procedures.
The
pilot
must
have
a
thorough knowledge of
all
emergency procedures
SO
that
in
the
event of
an
emergency,
reaction
will
be
precise
and
done with confidence. This is required so the pilot can cope
with
the demands of
an
emergency situation.
AIRSPEEDS FOR SAFE OPERATION
The
most critical time for an engine failure condition in a multi-engine airplane is during a
two
or three second period late
in
the takeoff
run
while the airplane
is
accelerating to a safe
engine failure speed. A detailed knowledge of recommended engine inoperative airspeeds
is
essential for safe operation of the airplane.
The airspeed indicator
is
marked with a
red
radial at the air minimum control speed and a
blue radial at the one engine inoperative best
rate~of-climb
speed to facilitate instant
recognition. The following paragraphs present a detailed discussion of the problems
associated
with engine failures during takeoff.
AIR MINIMUM CONTROL SPEED
The multi-engine airplane must reach the air minimum control speed (80 KIAS) before full
control deflections can counteract
the adverse rolling and yawing tendencies associated with
one engine inoperative and full power operation
on
the other engine. This speed
is
indicated
by
a
red
radial
on
the airspeed indicator.
INTENTIONAL ONE ENGINE INOPERATIVE SPEED
Although the airplane is controllable at the air minimum control speed, the airplane
performance is
so
far below optimum that continued flight near the ground
is
improbable. A
,,-/
more suitable intentional one engine inoperative speed is 95 KIAS.
At
this speed, attitude can
be
maintained more easily while the landing gear is being retracted and the propeller is being
feathered.
ONE ENGINE INOPERATIVE BEST ANGLE·Of·CLIMB SPEED
The one engine inoperative best angle-Qf-climb speed becomes important when there are
obstacles ahead
on
takeoff. Once the one engine inoperative best angle-of-climb speed is
~
reached, altitude becomes more important than airspeed until the obstacle is cleared. The
one engine inoperative best angle-at-climb speed
is
approximately 95 KIAS with wing flaps
and
landing gear
up.
