Above 5000 ft mixture may be leaned to obtain optimum engine efficiency according to
the markings provided on the fuel flow gauge (see below.)
Cruise
Cruise power should be set in accordance with the chart in Section 5. Maximum cruise
power setting is 75%. Recommended power setting is 70% or less.
The original propellers on FXFG have been replaced under an STC. The installed
propellers have an operating limitation between 2000 and 2350 rpm. You must avoid
continuous operation in this rpm range due to vibration. Therefore cruise rpm must be
kept to 2400 rpm or higher. To avoid confusion GSAK is operated the same way. The
cruise performance charts in section 5 reflect the limitation.
Mixture should be set using the fuel flow gauge, to the value from the B95 Cruise
Performance Chart (section 5) after manifold pressure and rpm are set. Once engine
temperatures stabilize mixture may be adjusted with the EGT to obtain maximum exhaust
gas temperature. On short flights (less than 15 minutes in cruise) it is not practical to use
the EGT.
Mixture should be set to full rich prior to performing maneuvers in which substantial
power changes will be required (e.g. stalls, steep turns, etc.) When practicing maneuvers
at density altitudes above 8000 feet it is acceptable to leave the mixtures slightly lean
from rich – move the levers back approximately ½ inch from full rich.
Holds
Due to the rpm limitation specified in STC SA00722CH rpm must remain above 2350.
