Cirrus SR20 and SR22 Flight Operations Manual
Section 3 Standard Operating Procedures
Procedure (Flow Pattern)
1. Fuel Pump ............................................................................... OFF
The Fuel Pump may be used for vapor suppression in cruise.
Vapor lock issues may be recognized by fluctuating EGT’s, CHT’s
and fuel flows. Rough engine operation may also be experienced.
2. Cruise Power............................................................................ SET
SR20/SR22 - Allow the aircraft to accelerate to cruise speeds
before setting cruise power. Select the desired percent power
considering range, endurance and desired performance for the
intended flight. Reference the MFD Engine page and adjust the
throttle to set the desired percent power.
SR22 Turbo - Allow the aircraft to accelerate to cruise speeds
before setting cruise power. Start setting cruise power by reducing
the throttle to 2500 RPM with maximum manifold pressure.
3. Mixture .............................................................. LEAN as Required
SR20/SR22 - Use the Lean Assist feature on the MFD Engine
page to set the mixture control for Best Power or Best Economy.
SR22 Turbo - Set the fuel flow to 17-17.6 GPH by adjusting the
mixture control after setting the throttle to 2500 RPM with
maximum manifold pressure. The above conditions will set
approximately 85% power. If a lower power setting is desired to
increase range/endurance reduce the throttle to the desired
percent power.
4. Engine Parameters ........................................................ MONITOR
Fuel BOOST must be used for switching from one tank to another.
Failure to activate the Fuel Pump before transfer could result in
delayed restart if the engine should quit due to fuel starvation.
5. Fuel Flow and Balance .................................................. MONITOR
Check fuel flow gauge and ensure fuel balance is within 7.5
gallons (SR20), 10 gallons (SR22).
