CAUTION
Pumping the throttle may cause raw fuel to accumulate in the intake air duct, creating a fire hazard in the event of a backfire. If this occurs, maintain a cranking action to suck flames into the engine. An outside attendant with a fire extinguisher is advised for cold starts without preheat.
During cold weather operations no indication will be apparent on the oil temperature gage prior to takeoff if outside air temperatures are very cold. After a suitable warm-up period (2 .to 5 minutes at 1000 RPM), accelerate the engine several times to higher engine RPM. If the engine accelerates smoothly and the oil pressure remains normal and steady, the airplane is ready for takeoff.
FLIGHT OPERATIONS
Takeoff is made normally with carburetor heat off. Avoid excessive leaning in cruise.
Carburetor heat may be used to overcome any occasional engine roughness due to ice.
When operating in temperatures below -18°C, avoid using partial carburetor heat. Partial heat may increase the carburetor air temperature
to the 0° to 21°C range, where icing is critical under certain atmospheric conditions.
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 2000 feet above the surface, weather permitting, even though flight at a lower level may be consistent with the provisions of government regulations.
