Single engine cruise mental checklist - SELFDR
Table of Contents


Should the decision be made to continue flying One Engine Inoperative in a light twin aircraft. The SELFDR mnemonic is a useful tool to be used for decision making. The SELFDR check should only be used after the commencement of phase one/initial actions and recommended restart attempt(s).

Secure - After feathering the inoperative engine, the engine should be secured in accordance to the flight manual or Company standard operating procedures. Typically this involves shutting off fuel supplies and disconnecting auxiliary devices.

Electrical load - Considerations must be put in to reduce electrical loads if appropriate. Although most modern light twins are designed to handle in flight electrical loads required with just one alternator, it is nevertheless good airmanship to preserve and protect the live engine and its components.

Lowest Safe - IFR flights will need to consider the lowest safe altitude for the current and planned airways. This will depend on the aircraft's current position, meteorological conditions and aircraft single engine performance.

Fuel - Fuel log should be updated when applicable, fuel management considerations include cross-fuel technique and managing the aircraft certified max fuel imbalance limit.

Direct Routing/Diversion - If applicable, a direct routing should be requested. The aircraft should land as soon as possible.

Radio - As with Aviate, Navigate, Communicate; communication comes last. Aircraft position, status and pilot intentions should be broadcast to the appropriate frequency.
