TIPS AND TECHNIQUES
FMS Philosophy
The FMS treats the flight plan as a continuous
sequence of legs, regardless of whether they are
part of a terminal area procedure or are in the
enroute structure. If you had chosen an IAF and the
last waypoint before the approach was the same as
the IAF, then the flight plan would naturally
sequence right into the approach with no further pilot
action required. If the last waypoint before the
approach were not the same as the IAF, then a
discontinuity would precede the approach. The
typical course of action, in that case, is to close the
gap and then the flight plan would sequence right
onto the approach with no further operator action.
The operation with VTF is slightly different, however.
In that case, you really have no choice but to
intervene when it's time to start the approach. There
are several options, including activating the leg to
the FAF, direct-to the leg to the FAF, or the
convenient FMS hook L4 LSK that says "Activate
Approach". That FMS hook is just a shortcut for
activating the leg to the FAF.
