Appendix C
GPS 155 Messages and Abbreviations
The GPS 155 uses the Message Page to communicate important information to you.
Some messages are advisory in nature, others are warnings that may require your intervention.
This appendix provides a complete list of GPS 155 messages and their meanings.
Altitude input fail - The altitude serializer input is no longer available to the GPS
155. Check the I/O settings and/or the serializer installation. If
enough satellites are available for a 3D fix, no pilot action is
required, provided no RAIM warnings are present. If only a 2D
fix is possible, the pilot should maintain the GPS altitude with-
in 1,000 feet of the pressure altitude from the Position page.
Approach deleted - The selected approach was deleted from the route because not
enough room existed to insert a SID or STAR.
Approach not active - The approach could not transition to the active phase because
the GPS SEQ switch is set to the HOLD position, the GPS APPR
switch has not been set to the ARM position, the automatic CDI
scale is not selected, or the automatic leg sequencing option is
disabled. Do not descend at the FAF.
Arm approach mode - Approach navigation is available. Set the GPS APPR switch to
the ARM position.

Arrvl at offst _____ - Your craft has entered the arrival alarm circle for the indicated
