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.
