battery provides a source of electrical power for starting the engine and a limited supply of electrical power for use in the event the alternator or generator fails. Most DC generators do not produce a sufficient amount of electrical current ... range of engine speeds. Some aircraft have receptacles to which an external ground power unit (GPU) may be connected to provide electrical energy for starting. These are very useful, especially during cold weather starting. Follow the manufacturer’s recommendations…

power from the main (takeoff) fuel tanks to reconfirm fuel flow prior to takeoff. This suggested check is not required prior to every flight. Crossfeed lines are ideal places for water and debris to accumulate unless they are used from ... time to time and drained using their external drains during preflight. Crossfeed is ordinarily not used for completing a flight with one engine inoperative when an alternate airport is nearby. Pilots should never use crossfeed during takeoff or for normal…
