Cruise; Revision 1 - Cirrus SR22 Pilot Operating Handbook

Section 4
Normal Procedures

Cruise

Normal cruising is performed between 55% and 85% power. The
engine power setting and corresponding fuel consumption for various
altitudes and temperatures can be determined by using the cruise data
in Section 5.
The selection of cruise altitude is made based on the most favorable
wind conditions and the desired power settings. These significant
factors should be considered on every trip to reduce fuel consumption.
For engine break-in, cruise at a minimum of 75% power until
the engine has been operated for at least 25 hours or until oil
consumption has stabilized. Operation at this higher power
will ensure proper seating of the rings, is applicable to new
engines,
replacement or top overhaul of one or more cylinders.
1. Fuel Pump................................................................................OFF
The Fuel Pump may be used for vapor suppression during
cruise.
The Fuel Pump must be set to BOOST during maneuvering
flight (i.e. flight training maneuvers, chandelles, stalls, etc.).
2. Cruise Power ........................................................................... SET
3. Mixture ............................................................... LEAN as required
4. Engine Parameters ........................................................ MONITOR
Fuel BOOST must be used for switching from one tank to
another. Failures 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
