Product Code:SAE AS8002
Title:Air Data Computer - Minimum Performance Standard
Issuing Committee:A-4 Air Data Working Group
Scope: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 flight instruments: pressure altitude; pressure altitude, baro-corrected; vertical speed; calibrated airspeed; mach number; maximum allowable airspeed; overspeed warning; and total air temperature. In addition, the computer may supply one or more of the following signals: pressure altitude, digitized; equivalent airspeed; true airspeed; static air temperature; altitude hold; airspeed hold; mach hold; angle of attack; flight control gain scheduling; and others.
