Maintenance; Active Operating Modes - Honeywell FMZ Series Pilot's Manual

Flight Management System (FMS) for the Agusta AW139/AB139 Helicopter

MAINTENANCE

The MAINTENANCE pages are used for controlling active operating
modes, listing failed sensors, and selecting true or magnetic mode for
the FMS.

Active Operating Modes

There are three configuration modes for the FMS:
1. Dual -- The active flight plan, performance entries, pilot--defined
waypoints, stored flight plans, and off--side radio tuning commands
are transferred to the other FMS automatically (no pilot action
required).
2. Independent -- Only off--side radio tuning commands are transferred
to the other FMS automatically.
3. Single -- The FMS in the single system mode monitors the
VOR/DME radio inputs and computes a radio position when
possible. The single FMS does not tune the VOR and DMEs.
However, the single FMS tunes all of the other radios (VHF COM,
ATC transponder, and so on) directly using the tuning command
outputs.
The APM, enables the selection of the operating group and selecting
and confirming the operating mode of multiple FMSs. In Figure 6--131,
the selected mode is DUAL, the selected operating group is DUAL.
