sUPPLE'IIENTARY
INFORMATION
CONCERNING
ENGINE FAITURE
DURING
TAKEOFF
The most
critical
time for an
engine failure condition
in a multi-engiae
aircraft
is
during a
two
or ttree second
period
late in
the
takeoff run
while
the
aircraft
is
accelerating
to a safe
engine
failure
speed,
A
de-
tailed
lsrowledge
of recommended
single-engine
airspeeds
in
Figure
3-l
is essential
for
safe operation
of
the
aircraft.
The airspeed
indicator
is
marked
with
a
Red
radial
line at
the
mini-
mum
single-engi.ne control
speed and a Blue radial
line at
the
best
single-
engine rate-of-climb
speed to
facilitate
instart recognitlon
The
follow-
ing
paragraphs
present
a detailed
diseussion
of the
problems
associated
with engine
failures
during takeoff.

MINIMUM
SINGLE-ENGINE
CONIROL
SPEED.
The
multi-engine
air-
craft must
reach
the minimum
control speed
(gb
MpH
IAS)
before fulI
control
deflections
carr-
counteract the adverse
rolling and
yawing
tenden-
cies
associated with
one
engine
inoperative
and
full
power
operation
on
the
other
engine.
This speed
is indicated
by a
Red radial
line
on the
air-
speed
indicator.
RECOMMENDED
SAFE
SINGLE-ENGINE
SPEED.
Although
the
alrcraft
is
controllable
at the
minimum
control speed,
the
aircraft
performance
is
so far below
optimum
that
continued
flight
near
the
ground
is improbable.
