Cruise

Normal cruising is performed between 55% and 75% 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 on the basis of the most
favorable wind conditions and the use of low 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.
