9.15. Engine-Out Performance Requirements for IFR Departures.
9.15.1. USAF aircrews flying multi-engine aircraft are required to ensure terrain and
obstacle clearance in the event of engine failure on takeoff. Plan one-engine inoperative
climb performance on departure IAW AFI 11-202 Volume 3, General Flight Rules and
MAJCOM directives. The following information is provided to assist aircrews in safely
complying with engine-out performance planning requirements.
9.15.2. Engine Inoperative Performance Considerations. There are several
considerations for computing obstacle clearance to comply with AFI 11-202 Volume 3
General Flight Rules requirements. Some are difficult to quantify in actual operational
practice. Normal IFR departure procedures add a safety factor in the form of the ROC to
ensure obstacle clearance when conditions are less than ideal. Any reduction in ROC for
engine-out performance computations will reduce that safety margin should an aircrew
experience an engine loss or loss of thrust on takeoff or departure.
9.15.2.1. Turning Performance. With one engine inoperative, turning performance
must be accounted for in computing aircraft capability to clear obstacles. Special
