Product Code:SAE AS420
Title:Flight Directors (Reciprocating Engine Powered Aircraft) (NONCURRENT Oct 1996)
Issuing Committee:A-4 Aircraft Instruments Committee
Scope:This Aerospace Standard establishes essential minimum safe performance standards for Flight Director instruments primarily for use with reciprocating engine powered transport aircraft, the operation of which may subject the instruments to the environmental conditions specified in Section 3.3. This Aerospace Standard covers Flight Directors for use on aircraft to indicate to the pilot, by visual means, the correct control application for the operation of an aircraft in accordance with a pre-selected flight plan.
