7. OPERATION IN FLIGHT.
a. See
airframe manufacturer's
instructions
for recommended
power
settings.
b. Move the
controls slowly
and smoothly.
In particular,
avoid rapid
opening
and closing
of the
throttle
on engines
with counterweighted
crankshafts.
There is a
possibility of
detuning the counterweights
with
subsequent
engine
damage.
c.
Fuel Mixture
Leaning
Procedure.
Improper
fuel/air mixture
during
flight
is responsible
for engine
problems,
particularly
during
take-off
and climb
power
settings.
The
procedures
described
in this
manual
provide proper
fuel/air
mixture
when
leaning
Lycoming
engines;
they
have proven
to be
both
economical
and practical
by
eliminating
excessive
fuel consumption
and
reducing
damaged
parts replacement.
It
is therefore
recommended
that
operators,
of
all
Lycoming
aircraft
power-plants,
utilize
the
instructions
in this publication
any time
the fuel/air mixture
is adjusted
during flight.
Manual
leaning may
be monitored
by exhaust
gas temperature
indication,
fuel
flow
indication,
and by
observation
of engine
speed
and/or
airspeed. However,
whatever instruments
are
used in monitoring
the
mixture,
the following
general
rules
should
be observed
by the
operator
of
Lycoming
aircraft
engines.
GENERAL
RULES
Never exceed
the maximum
red line cylinder
head temperature
limit.
For maximum
service life,
cylinder
head
temperatures
should
be
maintained
below
435°F.
(224
0
C.) during
high
performance
cruise
operation
and
below 400
F. (205°C.)
for
economy
cruise powers.
