IFD400 Series Pilot Guide
2-24 FMS Subsystem
Once on, the leg type is selected just like all other leg types but is
only available after a leg that is not part of a terminal procedure.
Select the “Orbit <waypoint>” option in the standard FMS insert
cursor drop down list.
Circular Orbit Dropdown Selection
The orbit radius can range from 0.5nm to 100nm. The FMS will
not actually fly to the orbit fix and instead, will fly to the point
where the leg to the fix intercepts the orbit.
Orbit Row in Flight Plan
If the orbit radius is larger than the distance from the aircraft to
the orbit fix, then the aircraft will intercept the orbit on the
extended radial between the orbit fix and the aircraft. Just like a
traditional holding pattern, there is no insert cursor between a fix
and a subsequent orbit. The only way to get out of an orbit is to
command a Direct-To or activate a different leg. The orbit size
can be changed while it is active but no path to reacquire the orbit
is depicted on the map.
