This Aerospace Standard covers an air data computer characterized by the concept of transducing and computing the majority of air data requirements for an aircraft. The display instruments and other using subsystems are not considered in this scope except where they perform computing operations for output parameters as covered by this specification. The computer may accept the inputs and provide the outputs listed in paragraphs 2.1 and 2.2 respectively. The computer may also provide an altitude encoder output for IFF Mark X ¯ ¯ (SIF)/Air Traffic Control Radar Beacon System SIF/ATCRBS; in which case AS 855* "Altitude Device Providing Outputs for Automatic Pressure Altitude Reporting" shall be referred to for applicable minimum standards. (Note - Reference to air data computer in subsequent paragraphs will be designated as "instrument".)
This Standard covers air data equipment (hereinafter designated the instrument) which when connected to sources of aircraft electrical power, static pressure, total pressure and outside air temperature (singly or in combination) provides some or all of the following computed air data output signals: Pressure Altitude* Total Temperature* Pressure Altitude (Reporting) Altitude Rate Baro-Corrected Pressure Altitude* Overspeed Warning Vertical Speed* Altitude Hold Computed Airspeed* Airspeed Hold Mach Number* Mach Hold Maximum Allowable Airspeed* qc (impact pressure) Static Air Temperature (*when used as an alternate for total temperature) True Airspeed Others
This standard covers three basic types of total-temperature-measuring instruments used as a means of determining the total temperature developed by adiabatic heating of the air due to motion of the aircraft through the air.
This recommended practice covers the requirements for gyroscopically stabilized Directional Indicating Systems, which will operate as a 1°/hour latitude corrected, free directional gyro or as a slaved gyro, magnetic compass with 1/2° accuracy.
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 SAE Aerospace Standard (AS) covers automatic 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.

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.
This AIR is concerned only with aspects directly relating to available accuracy. While well-designed photoelectric, inductive or capacitive readers and pressure regulators, and other accessories are highly desirable for convenience and production rate, they are considered to be outside the scope of this AIR.
