This Aeronautical 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.

These recommendations cover the mechanical and electrical installation and installation test procedures for automatic pilots of the type normally used in transport type aircraft. The material in this ARP does not supercede any airworthiness requirement in the Civil Air Regulations.

This Aeronautical Standard covers the capacitance sensor type of instrument.

This standard provides minimum performance criteria for air data instruments intended to provide cockpit indication of: a Indicated airspeed (Vi) b Computer airspeed (Vc) c True airspeed (Vt) d Equivalent airspeed (Ve) e Mach number (M) f Altitude (H) g Vertical speed (Hpr) h Maximum operating limit speed (Vmo) i True angle of attack (αt) j Free air temperature (Tfat) k Total temperature (Tt) These functions shall be derived from a central air data computer (AS 417) and through system wiring applied to the respective indicator.

All automatic altitude reporting digitizer equipment manufactured under this standard shall comply with the requirements as specified up to its maximum range as indicated on the equipment nameplate.

This Aerospace Standard covers two basic types of pitch and roll indicating instruments as follows: Type I: Direct coupled to gyro Type II: Electrical repeating

This AS covers __________ which measure and display __________ or This AS covers __________ basic types of (no capitals) instruments as follows: Note: Each type number to be followed by a brief description as it would if the scope were covering only a single type. As many types as required may be used.

This specification covers the design and performance requirements for a single axis, four load-factor level counting accelerometer group referred to hereafter as “equipment.”

This specification covers the design and performance requirements for a single axis, four load-factor level counting accelerometer group referred to hereafter as “equipment.”

The instrument system specified shall accept an input of static pressure and in some equipment other inputs that contribute altitude information to provide a visual indication of pressure altitude. If equipped with an automatic correction mechanism, it shall indicate by a positive means when the automatic correction mechanism is not in use. If the static source pressure error compensating mechanism is operational it shall be functional throughout the required operating envelope of the particular aircraft. Each aircraft type has its own static source error data which shall be obtained from the airframe manufacturer’s certified data. When a Central Air Data Computer is used in the altimeter system, the CADC shall be certified to its own governing document and the altimeter system (CADC and display) shall comply with the requirements of this document. NOTE: The instrument system specified herein does not include the aircraft pressure lines and pressure sources.

These recommendations cover the mechanical and electrical installation and installation test procedures for Compass Systems of the type normally used in transport type aircraft. The recommendations in the ARP do not supersede any airworthiness requirements in Civil Air Regulations.
