Safety
Information
procedure calls for
simulating
one engine
inoperative
by reducing the
power
lever (throttle) on one engine
to
idle
while
operating at an airspeed
above
Vsse.
Power on the other engine is
set at maximum, then
airspeed
is
reduced
at approximately one knot
per
second
until
either
Vmca or stall
warning
is
obtained.
During this transition, rudder should be
used
to maintain directional
control,
and
ailerons
should be used to
maintain
a
5°
bank toward the
operative engine. At the first sign of either Vmca or
stall
warning
(which
may
be evidenced
by
inability
to maintain
longitudinal,
lateral
or directional
control, aerodynamic stall buffet,
of stall
warning
horn sound), recovery must be
initiated
immediately
by reducing power to idle on operative engine
and
lowering the
nose
to regain Vsse. Resume normal
flight. This entire
procedure
should be used at
a safe
altitude of at least
5,000
feet above the
ground
in
clear
air only.
If stall
warning
is detected
prior to the first sign of
Vmca,
an engine-out
minimum
control speed
demonstration
cannot
be accomplished
under the
existing density altitude and gross
weight
conditions
and should not be attenipted.
