NORMAL PROCEDURES
WARM-UP
In very cold weather, no oil temperature indication need be appar-
ent before takeoff. After a suitable warm-up period (2 to 5 minutes at
1000 RPM), with cylinder head temperatures showing above 200°F, the
engine is ready for takeoff if it accelerates smoothly and the oil pres-
sure is normal and steady. '
IN FLIGHT
During let-down, observe engine temperatures closely and carry
sufficient power to maintain them in the recommended operating range.
HOT WEATHER OPERATION
Refer to the general warm temperature starting information under
Starting Engine in this section. Avoid prolonged engine operation on
the
ground.
NOISE ABATEMENT
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 on 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 VFR over outdoor assemblies of
persons, recreational and park areas, and other noise-sensitive
areas should make every effort to fly not less than 2,000 feet above
the surface, weather permitting, even though flight at a lower level
may be consistent with the provisions of government regulations.
(2) During departure from or approach to an airport, climb after
takeoff and descent for landing should be made so as to avoid pro-
longed flight at low altitude near noise-sensitive areas.
NOTE
The above recommended procedures do not apply where
they would conflict with Air Traffic Control clearances
4-22
or ~nstructions, or where, in the pilot's judgement, an
al titude of less than 2,000 feet is necessary for him to
adequately exercise his duty to see and avoid other air-
craft.
~he certif~cate~ noise level for the Model R172K at 2550 pounds
maximum wel~ht.IS 74.S d,s\A). ~o determination has been made by
the Federal AVIatIOn Admintstration that the noise levels of this air-
plane are or should be acceptable or unacceptable for operation at into
or out of, any airport. ' ,
