ARINC Characteristic 755 defines a multi-mode receiver capable of providing flight path deviation guidance (corrections) to the aircraft during the approach and landing phase. The data source may be from an Instrument Landing System (ILS), a Microwave Landing System (MLS) or an GNSS Landing System (GLS).
Supplement 5 adds annunciations defined in RTCA/DO-253D – MOPS for GPS LAAS Airborne Equipment. GNSS Data and GLS Config Validity ARINC 429 Labels are also updated. The range for Selected Glide Path Angle is corrected.
