Cirrus SR20 and SR22 Flight Operations Manual
Section 3 Standard Operating Procedures
3. Mixture ........................................................................ As Required
SR20 - Set the mixture full rich for all altitudes.
SR22 - Lean mixture as required for altitude to maintain maximum
climb power using the max power fuel flow chart near MFD.
SR22 Turbo - Climbs can be made at full power with the mixture
set full rich or at an economy cruise climb. Lean the mixture to
17 - 17.6 GPH with the throttle full open to set up an economy
cruise climb. Maintain an airspeed of 130 KIAS during an
economy cruise climb.
4. Engine Parameters ............................................................ CHECK
Check all engine parameters for any abnormal indications that
may indicate impending engine problems.
5. Fuel Pump (SR20/SR22) .........................................................OFF
Select fuel pump OFF above 1000' AGL unless the takeoff was
made with warm or hot fuel.
Fuel Pump (SR22 Turbo) .......................................... LOW BOOST
Select LOW BOOST 30 minutes into cruise flight to reduce the
likelihood of vapor lock, which may be due to a combination of
warm fuel and high altitude. If vapor lock is suspected at altitudes
above FL180 set the fuel pump to HIGH BOOST/PRIME until the
warm fuel has time to cool.
Fuel boost should be left on during takeoff and for climb as
required for vapor suppression with hot or warm fuel.
Avionics Configuration
• Autopilot - engage modes as desired past 700 AGL when time
and workload permit,
• MFD - Complete Climb Checklist, monitor Map for situational
awareness,
• PFD - Monitor aircraft flight parameters and system status.
