Extract from a Cessna POH
Quote:
ENGINE FAILURE DURING FLIGHT (Restart Procedures)
1. Airspeed -- 65 KIAS.
2. Fuel Shutoff Valve -- ON (push full in).
3. Fuel Selector Valve -- BOTH.
4. Auxiliary Fuel Pump Switch -- ON.
5. Mixture -- RICH (if restart has not occurred).
6. Ignition Switch -- BOTH (or START if propeller is stopped).
NOTE
If the propeller is windmilling, the engine will restart automatically within a few seconds. If the propeller has stopped (possible at low speeds), turn the ignition switch to START, advance the throttle slowly from idle (assumed to be WOT)and lean the mixture from full rich as required for smooth operation.(A mixture sweep)
7. Auxiliary Fuel Pump Switch -- OFF
The C152 POH does not show an auxiliary fuel pump switch. While the above emergency checklist is valid in some series of Cessna singles, the incident described earlier left the instructor with precious little time/altitude to get the engine re-started. His prompt actions were successful and nobody got their feet wet.
