Scope
Content
This standard provides minimum performance criteria for air data instruments intended to provide cockpit indication of:
  1. a
    Indicated airspeed (Vi)
  2. b
    Computer airspeed (Vc)
  3. c
    True airspeed (Vt)
  4. d
    Equivalent airspeed (Ve)
  5. e
    Mach number (M)
  6. f
    Altitude (H)
  7. g
    Vertical speed (Hpr)
  8. h
    Maximum operating limit speed (Vmo)
  9. i
    True angle of attack (αt)
  10. j
    Free air temperature (Tfat)
  11. 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.
