FREDA

FREDA is a mnemonic used in aviation, particularly light aircraft listing critical items for a pilot to check periodically, e.g. at each waypoint.

It stands for:


 * Fuel - is there sufficient fuel and is the correct tank selected? Does the tank need to be changed or the fuel balanced?
 * Radios - is the correct frequency set? Transmit an update on location if appropriate.
 * Engine - are the temperatures and pressures OK?
 * Direction Indicator - is it aligned with the compass?
 * Altitude - is the altitude correct and is the correct pressure set on the altimeter?
