Approach Basics (GX50/60)

Flight Plan

Waypoint

Sequencing

A flight plan will sequence to the next leg of the flight plan as the aircraft crosses to the bisector that runs through the “TO” waypoint. The bisector is defined as the angle that is half of the angle between the current leg and the next leg. When the unit is on Hold, or there is no next leg, the bisector is perpendicular to the inbound course to that waypoint. See the section about Holding Patterns on page 24 for more details on FROM/TO waypoints.

Note

If you manually select a leg that you have already passed, the Apollo GX will immediately sequence to the next leg.

In order to keep the Apollo GX from immediately sequencing when such a leg is selected, place your flight plan on hold by

pressing the OBS/HLD key prior

to

selecting

the leg. It is then

necessary

to

re-enable

sequencing, by

pressing

the

OBS/HLD key again, when established inbound on the desired leg.
