Flight Management System (FMS) for the Agusta AW139/AB139 Helicopter
Waypoint speed constraints in the cruise or descent phase of flight
result in the FMS applying the speed constraint to all legs after the
waypoint. As the aircraft approaches the waypoint, the FMS anticipates
the speed constraint so that the aircraft crosses the waypoint at the
speed constraint. The cruise phase of flight is defined as the legs of the
flight plan past the TOC and prior to the TOD. The descent phase of
flight is defined as the legs of the flight plan past the TOD.
To insert a waypoint speed constraint, follow Procedure 7--5.
Step
Procedure 7- -5 Inserting a Waypoint Speed
1
Completely initialize the PERFORMANCE INIT pages.
2
Enter the speed constraint into the scratchpad followed by
a slash (/). The entered speed is either a CAS or MACH.
3
Push the right line select key adjacent to the lateral
waypoint on the ACTIVE FLT PLAN page. For example,
Figure 7--30 shows a speed constraint of 120 kts desired
for waypoint FGT. The speed constraint was entered into
the scratchpad (e.g., 120/) and then line select 2R was
pushed.
