Flight Management System (FMS) for the Agusta AW139/AB139 Helicopter
To initialize FMS position, the appropriate LOAD prompt (1R, 2R or 3R)
is pushed. The selected position becomes the FMS position, as shown
in Figure 4--8. Selecting the LOAD prompt initializes connected sensors
receiving inputs from the FMS.
The position loaded on one FMS is transferred to the cross--side FMS
so that both have the same initial position. Selecting the LOAD prompt
continues the preflight process.
