power to 75% or less and land as soon as possible. Do not set the mixture too rich for
descent or landing. Refer to the amplified discussion on page 3-21.
3.3. Improper Mixture Setting
If fuel management is correct and the engine driven fuel
pump is working properly, it is possible the mixture is either too lean or too rich. If
above 15,000 ft, it is likely the mixture is too rich and may need to be leaned. If below
15,000 ft, the mixture may be too lean and should be richened.
WARNING
If the backup boost pump is in use during an emergency, proper leaning
procedures are important. During the descent and approach to landing
phases of the flight, DO NOT set the mixture to rich as prescribed in the
normal before landing procedures, and avoid closing the throttle completely.
If a balked landing is necessary, coordinate the simultaneous application of
mixture and throttle. Please see amplified discussion on page 3-21.
