AS791: Remote Servoed Air Data Instruments for Subsonic Aircraft - Technical Standard

Features

Issuing Committee: A-4 Aircraft Instruments Committee

Scope

Content

This standard provides minimum performance criteria for air data instruments intended to provide cockpit indication of:

a
Indicated airspeed (V_i)
b
Computer airspeed (V_c)
c
True airspeed (V_t)
d
Equivalent airspeed (V_e)
e
Mach number (M)
f
Altitude (H)
g
Vertical speed (H_pr)
h
Maximum operating limit speed (V_mo)
i
True angle of attack (α_t)
j
Free air temperature (T_fat)
k
Total temperature (T_t)

These functions shall be derived from a central air data computer (AS 417) and through system wiring applied to the respective indicator.
