For monochrome head up displays used as airborne multipurpose electronic displays use for sections 3.9, 3.12, 3.13, 3.14 and 4.2.4 of SAE AS8055 the coresponing sections 3.9, 3.12, 3.13, 3.14 and 4.2.3 of SAE AS8034A
Deviates from ETSO‐C139 paragraph 3.1.1 to use RTCA document DO‐214a “Audio Systems Characteristics and Minimum Performance Standards for Aircraft Audio Systems and Equipment” instead of DO‐214.
Deviates from Radio Technical Commission for Aeronautics (RTCA) Document DO‐265, Minimum Operational Performance Standards for Aeronautical Mobile High Frequency Data Link (HFDL)”, dated 14/12/2000 by implementing Data‐2 Direct Link Service (DLS) Protocol
Deviates from ED‐73E by replying to Mode A/C/S All‐Call and Mode S‐only All‐Call interrogations and by transmitting on top or bottom antenna when TCS is set to 1 or 2, for transponder limited to installation where ground status is wired.
Deviates from EUROCAE ED‐102A by applying a timeout of 2.8 seconds instead of 2 seconds and from ED‐14G section 21.5 Category M by allowing different values.
Allows the use of an estimated height above ground instead of the radar altimeter height in some cases, when no radar altimeter is installed. Allows the use of EUROCAE ED-73E / RTCA DO-181E instead of EUROCAE ED-73C /RTCA DO-181D.
If RTCA/DO-181E is used as an equivalent document for EUROCAE ED-73E to deviate from RTCA/DO-181E Section 2.2.22.h to not interface with FAA TSO-C119a (RTCA/DO- 185 compatible) TCAS units.
