Notes:
[1] Label 116 is not properly encoded in the GNS 480 Software Version 1.0, 1.1, and 1.2.
Equipment using this label should not be interfaced via ARINC 429 to a GNS 480 with one
of these software versions.
[2] Binary DDM for localizer deviation is limited to ±0.155.
[3] Binary DDM for glideslope deviation is limited to ±0.175.
[4] The GNS 480 Equipment Hex ID is 002 for configurations 1, 2, and 5. For configuration 4,
the Hex ID is 010 when a localizer is tuned, and 011 when a VOR is tuned.
[5] Vertical deviation and scale factor (labels 117G and 327G) were added to the outputs as
part of GNS 480 Software Version 2.0 and do not exist in version 1.3.
