A cruise climb speed of 104 KIAS or higher is also recommended.

This combination of reduced power and increased climb speed provides better engine cooling, less engine wear, reduced fuel consumption, lower cabin noise level, and better forward visibility.

When reducing power the throttle should be retarded first, followed by the propeller control.

Themixture control should remain at full rich during the climb.

Cylinder head temperatures should be monitored during climb and should be kept below 460 ° at all times.

During climbs under hot weather conditions, it may be necessary to use LO auxiliary fuel pump for vapor suppression.

Consistent operational use of cruise climb power settings is strongly recommended since this practice will make a substantial contribution to fuel economy and increased engine life, and will reduce the incidence of premature engine overhauls.
