CREATING A HOLDING PATTERN
A hold can be put on any waypoint that has a fix terminated leg
–
waypoints that terminate with a lat/lon position such as navaids,
enroute waypoints, user waypoints, airports, etc. Legs that
terminate at an altitude, DME distance, radial crossings, etc. do
not support attaching a hold. Hold fixes are always fly-over
waypoints and not fly-by waypoints.
Use the edit cursor on the flight plan to select the waypoint of
interest, then push the bottom right knob or touch the desired
location to display a drop down list of options. Near the top of that
list, you will see
“Hold at <waypoint name>”. Scroll to highlight
that drop down list entry and push the knob again. You have just
added a holding leg, populated with standard hold data.
Alternatively, use an insert cursor by positioning it where you
want to insert a hold in your flight plan. Push in the bottom right
knob or touch the position on the glass. Note that a hold is
available via the drop down list. Scroll up or down the dropdown
list as required and push the bottom right knob or touch the hold
option in the list to insert a hold flight plan leg.
TIPS AND TECHNIQUES
Using Holding Patterns
The hold pattern leg type has a field for the inbound
course to the hold waypoint. The hold pattern turns
left or right as specified in the hold pattern at the
hold waypoint.
For example, if ATC issues a “Hold
east of <waypoint>
”, a hold course of 270° should be
entered in the hold leg.
The nav database may contain multiple published holding
patterns for a given fix (e.g. enroute hold, high altitude hold, low
altitude hold, SID hold, STAR hold, etc). The FMS will use a
standard hold pattern when there is no defined published hold.
For those fixes that have multiple published holds associated with
them, a dropdown menu will be presented showing the various
hold patterns, thereby allowing you to choose the desired or
assigned hold pattern (course, turn direction, and leg length/time).
