Freda

:"This article is about the aviation checklist.":"For information about the Lord of the Rings character, see Freda".

FREDA is a checklist widely used in aviation. It represents the checks the pilot should conduct frequently during flight to ensure the aircraft is set optimally for straight and level flight, and that no problems are imminent.

It stands for -

* Fuel : ensure fuel is sufficient and being consumed at the expected rate. 'Lean out' the carburettor to the most economical setting. Set the fuel selector switch to take fuel from one or other of the wing tanks, or both, depending on fuel remaining and aircraft balance limits.

* Radio : ensure the radio is tuned to the correct frequency for the nearest airfield. Listen for announcements. Communicate with airfield when entering or leaving restricted airspace.

* Engine : check oil temperature and pressure, and other engine indicators.

* DI : check directional indicators (compass, gyroscope, artificial horizon, etc.) to ensure correct heading.

* Altimeter : check altimeter shows correct altitude. Gain or lose height if necessary. Adjust altimeter to the correct atmospheric pressure setting for the local area.
