(N/W/C) Engine Failure after Takeoff
• Maximum climb performance can be achieved by raising the failed engine 3
to 5° up and displacing the slip skid indicator one-half to three-quarters of a ball width toward the good engine.
• If the auto feather system is being used, retarding the POWER lever below
approximately 90 percent N1 before the feathering sequence is complete will deactivate the auto feather circuit and prevent automatic feathering.
