Holding
Patterns
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. Like the procedure turn, the steps
will always be:
·
First, suspend sequencing
·
Second, set the inbound course.
·
Third, enable sequencing.
1. Verify that sequencing is suspended, the
OBS/HLD annunciator is lit prior to crossing the
waypoint. Suspend sequencing by pressing the
OBS/HLD key.
2. After crossing the waypoint, establish the desired
inbound course to the waypoint by pressing
ENTER
at the “Set OBS Course” message. Select the
inbound course with the
SMALL and LARGE knobs.
Set waypoint sequencing to manual. Now, 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. The following example shows
holding at the Newburg VOR (UBG) with 020°
inbound selected as the OBS course to UBG.

If sequencing is enabled
on the "TO" side of a line
perpendicular to the
destination waypoint, the
flightplan will sequence to
the "NEXT" waypoint
when you cross the line.
If sequencing is enabled
onthe"FROM"sideofa
line perpendicular to the
inbound course at the
active destination waypoint,
the flightplan will sequence
