Flight Management System (FMS) for the Agusta AW139/AB139 Helicopter
DESCENT
The FMS calculates a TOD point based on the destination elevation and
any entered altitude constraints. Once in descent, the FMS sets the
target altitude to the altitude selector or the next constraint, whichever
is higher.
ARRIVAL
When within 200 flight plan miles of the destination airport, the
ARRIVAL prompt is displayed at 6R, as shown in Figure 4--41. Pushing
the ARRIVAL prompt selects an arrival procedure or surface. The
ARRIVAL page is always accessed from the NAV INDEX.
