SAE AS8002B

This SAE Aerospace Standard (AS) covers air data computer equipment (hereinafter designated the computer) which when connected to sources of aircraft electrical power, static pressure, total pressure, outside air temperature, and others specified by the manufacturer (singly or in combination) provides some or all of the following computed air data output signals (in analog and/or digital form) which may supply primary and/or standby flight instruments: Pressure Altitude Pressure Altitude, Baro-Corrected Vertical Speed Calibrated Airspeed Mach Number Maximum Allowable Airspeed Over-speed Warning Total Air Temperature This standard was revised to: update certain design requirements so they apply to all air data computers; add a new equipment designation (type) for installations that require more stringent altitude tolerance requirements; update the environmental test requirements to include those of DO-160G as they apply to air data computers and add some information regarding RVSM installations to increase the awareness of related requirements not covered by this standard. A generally accepted methodology for economically showing compliance to this standard was also included in an appendix.
