References: FAA-H-8083-2, FAA-H-8083-3, FAA-H-8083-15, FAA-H-8083-25; FAA-P-8740-66; POH/AFM

Objective: To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with flight solely by reference to instruments with one engine inoperative. Note: See Appendix 2: Safety of Flight and Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.

Knowledge — The applicant demonstrates understanding of:

PA.X.C.K1 Procedures used if engine failure occurs during straight-and-level flight and turns while on instruments.

Risk Management — The applicant is able to identify, assess, and mitigate risk associated with:

PA.X.C.R1 Identification of the inoperative engine.

PA.X.C.R2 Inability to climb or maintain altitude with an inoperative engine.

PA.X.C.R3 Low altitude maneuvering, including stall, spin, or controlled flight into terrain (CFIT).

PA.X.C.R4 Distractions, task prioritization, loss of situational awareness, or disorientation.

PA.X.C.R5 Fuel management during single-engine operation.

Skills — The applicant exhibits the skill to:

PA.X.C.S1 Promptly recognize an engine failure and maintain positive aircraft control.

PA.X.C.S2 Set the engine controls, reduce drag, identify and verify the inoperative engine, and simulate feathering of the propeller on the inoperative engine (evaluator should then establish zero thrust on the inoperative engine).

PA.X.C.S3 Establish the best engine-inoperative airspeed and trim the airplane.

PA.X.C.S4 Use flight controls in the proper combination as recommended by the manufacturer, or as required to maintain best performance, and trim as required.

PA.X.C.S5 Verify the prescribed checklist procedures used for securing the inoperative engine.

PA.X.C.S6 Attempt to determine and resolve the reason for the engine failure.

PA.X.C.S7 Monitor engine functions and make necessary adjustments.

PA.X.C.S8 Maintain the specified altitude ±100 feet or minimum sink rate if applicable, airspeed ±10 knots, and the specified heading ±10°.

PA.X.C.S9 Assess the aircraft’s performance capability and decide an appropriate action to ensure a safe landing.

PA.X.C.S10 Avoid loss of airplane control or attempted flight contrary to the engine-inoperative operating limitations of the airplane.

PA.X.C.S11 Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate. Private Pilot for Airplane Category ACS (FAA-S-ACS-6C) 61
