Flight Management System (FMS) for the Agusta AW139/AB139 Helicopter
Step
Procedure 6- -22 Orbit Pattern Definition
8
Enter the orbit direction at 3R (when different from the
default). The direction is specified as counterclockwise
(ccw) or clockwise (cw).
9
Select ACTIVATE (6R) or CLEAR (6L).
Orbit patterns are designated with a reverse video O on the pattern
waypoint. As the aircraft approaches the orbit, the aircraft transitions
onto the orbit and flies at the specified radius around the waypoint. A
prompt on the active flight plan page is used to reverse the direction of
flight once in the orbit. The reversal turn is always executed to the
outside of the orbit.
DELETING AN ORBIT PATTERN
An orbit pattern is deleted from the flight plan by selecting *DELETE*
from the scratchpad to the appropriate waypoint. On the active flight
plan pages, *DELETE* cannot be used within a minute of the pattern.
In this case, pushing the EXIT prompt (6L) removes the pattern.
EXITING AN ORBIT PATTERN
One minute before an orbit is entered and while in the orbit, the EXIT
prompt is displayed at 6L on the active flight plan page. When EXIT is
selected, the aircraft immediately leaves the orbit and proceeds to the
next waypoint in the flight plan.
