Holding Patterns (GX50/60)
A holding pattern is operationally the same as a
procedure turn except that you usually intend to make
repeated crossings of the waypoint on a specific
inbound course. For a holding pattern, like for the
procedure turn, the steps will always be to:
1. First, verify that sequencing is suspended, the
OBS/HLD annunciator is lit, or suspend
sequencing by pressing the OBS/HLD button.
2. Second, after crossing the waypoint, establish the
desired inbound course to the waypoint by pressing
DIRECT-TO twice or pressing ENTER for the
“Set OBS Course” message. Select the inbound
course with the SMALL and LARGE knobs, then
press ENTER.
3. Enter the holding pattern by the most appropriate
entry method. For example, Direct, Teardrop, or
Parallel, just as you would enter that holding
pattern at a VOR. Finally, when you are ready to
exit the holding pattern, press OBS/HLD while
still on the “TO” side of the waypoint to enable
sequencing the next time you cross the waypoint.
While you are in a holding pattern, the CDI/HSI
cross-track deviation display and the TO/FROM flag
will behave almost exactly the way they would if you
were holding at a VOR. The TO/FROM flag will
display “TO” prior to reaching the waypoint. The
TO/FROM flag will display “FROM” after crossing
the waypoint. TO and FROM is determined by
position relative to a line drawn perpendicular to the
