Product Code:SAE AS440
Title:Automatic Pilots (Turbine Powered Subsonic Aircraft)
Issuing Committee:A-4 Aircraft Instruments Committee
Scope:This SAE Aerospace Standard (AS) covers autoatic pilots intended for use on aircraft to automatically operate the primary and trim aerodynamic controls to maintain stable flight and/or to provide maneuvering about any of the three axes through servo control. Automatic control functions essential for primary or augmented flight control are excluded.
