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.
