Flight Operations; Hot Weather Operation - Cessna 172P Pilot's Operating Handbook And Flight Manual

FLIGHT OPERATIONS
Takeoff is
made
normally with
carburetor heat off. Avoid
excessive
leaning
in
cruise.
Carburetor heat may
be used
to
overcome
a,ny occa,sional engine
roughness due to
ice.
\ühen operating
in
temperatures below
-18oC,
avoid using partial
carburetor
heat.
Partial
heat
may
increase
the
carburetor air temperature
to
the O"
to
21oC range, where
icing is critical under certain atmospheric
conditions.
HOT WEATHER OPERATION
R,efer
to
the general warrn temperature starting information under
Starting Elngine in this

Avoid prolonged engine operation
on
the
ground.

Increased emphasis on improving the
quality of our
environment
requires renewed effort
on the
part of all pilots to minimize
the
effect of
airplane noise ou
the
public.
We,
as pilots,
can demonstrate our concern for.environmental im-
provement,
by
application of the following suggested procedures,
and
thereby tend to build public support for aviation:
1,. Pilots
operating aircraft under
VFF,
over outdoor assemblies of
persons, recreational and park areas, and other noise-sensitive
a,rea,s
should
make
every effort
to
fly
not less than
2000
feet above
the surface,
weather
permitting,
even
though
flight
at
a
lower
level
may
be
consisterrt with
the
provisions
of
government regulations.
2,
During
departure from
or
approach
to
an airport, climb
after
takeoff
and
descent
for landing
shoutd be made so as
to
avoid
prolonged
flight
at
low altitude near noise-sensitive
areas.
