through the engine. The amount of damage will vary and may
not become evident for many hours. However, the engine may
be severely damaged and may fail shortly following application
of high power. Proper procedures require thorough application
of preheat to all parts of the engine. Hot air must be applied
directly to the oil sump and external oil lines as well as the

cylinders, air intake and oil cooler. Because excessively hot air
can damage non-metallic components such as composite
parts, seals, hoses, and drives belts, do not attempt to hasten
the preheat process.
1. Ignition Switch ..........................................................................OFF
• WARNING •
Use extreme caution when pulling the propeller through by
hand. Make sure ignition switch is OFF, keys are out of
ignition, and then act as if the engine will start. A loose or
broken ground wire on either magneto could cause the engine
to fire.

3. External Power (If applicable) .......................................CONNECT
4. Brakes ..................................................................................HOLD
5. Bat Master Switches ........................................ ON (check voltage)
6. Mixture ......................................................................... FULL RICH
7. Power lever..........................................................FULL FORWARD
8. Fuel Pump.....................................................PRIME, then BOOST
• Note •
Serials 0002 - 0278 before SB 22-73-01: In temperatures
down to 20°F, hold Fuel Pump switch to PRIME for 60-120
seconds prior to starting.
Serials 0002 - 0278 after SB 22-73-01 and 0279 and
subsequent: In temperatures down to 20°F, hold Fuel Pump
switch to PRIME for 15 seconds prior to starting.

Hot Weather Operation
Avoid prolonged engine operation on the ground.
• Note •
Fuel BOOST must be ON for engine start and takeoff, and
should be ON during climb for vapor suppression which could
occur under hot ambient conditions or after extended idle.

Noise Characteristics/Abatement
The certificated noise levels for the Cirrus Design SR22 established in
accordance with FAR 36 Appendix G are:
No determination has been made by the Federal Aviation
Administration that the noise levels of this airplane are or should be
acceptable or unacceptable for operation at, into, or out of, any airport.
The above noise levels were established at 3400 pounds takeoff
weight and 2700 RPM.
Recently, increased emphasis on improving environmental quality
requires all pilots to minimize the effect of airplane noise on the public.
The following suggested procedures minimize environmental noise
when operating the SR22.
• Note •
Do not follow these noise abatement procedures where they
conflict with Air Traffic Control clearances or instructions,
weather considerations, or wherever they would reduce safety.
1. When operating VFR over noise-sensitive areas, such as outdoor
events, parks, and recreational areas, fly not less than 2000 feet
above the surface even though flight at a lower level may be
