SAE AS791 1966 Edition, August 15, 1966
Remote Servoed Air Data Instruments for Subsonic Aircraft
Description / Abstract:
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 (at)
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.
