holding point (MAHP). If a missed approach is required, press the
ic waypoint sequencing and sequence the approach to the MAHP. See page 62 for more information on missed approaches.
Why won’t my unit automatically sequence to the next waypoint?
The GPS 400 will only sequence flight plan waypoints when automatic sequencing is enabled (i.e., no "OBS" or "SUSP" annunciation directly

above the key). For automatic sequencing to occur, you must also cross the "bisector" of the turn you are navigating. The bisector is a perpen-
dicular line between two flight plan legs which crosses through the waypoint common to both legs.
How do I fly the GPS with an autopilot and HI heading bug?
If you do not have an HSI, you should make your course selections on the external CDI's OBS knob and the HI heading bug.
When should I use the O

happens when I do?
The most common application for using the
O
key is the missed approach. The GPS 400 will
