SEC F-PLN Page

The FMS provides a secondary flight plan which can be entirely different from the

active flight plan or can be a modified version of the active flight plan. The

secondary flight plan is for use in preplanning or evaluating changes to the active

plan. The SEC F-PLN INIT page is accessed by the SEC F-PLN key.

The existing active flight plan may be copied for evaluation of modifications by

pushing LSK 3L (COPY ACTIVE). This causes the display to change to the SEC

F-PLN page 1. If it is necessary to completely clear the secondary flight plan,

pushing 4L (CLEAR SEC) leaves the SEC F-PLN INIT page displayed.

When NAV is engaged, the prompt ACTIVATE SEC* in 4R is not displayed

unless the first leg of the secondary flight plan is the same as the current active

flight plan leg. If that is the case and 4R is pushed, the secondary flight plan

immediately becomes the active flight plan and the display changes to F-PLN

INIT page 1. The aircraft will now be on the same active lateral leg (no lateral

maneuver will occur).

If NAV is not engaged, ACTIVATE SEC* is always displayed in 4R. Upon

activation of the secondary flight plan the previously active flight plan becomes

the new secondary.

If the flight crew had previously entered in 5L of the SEC F-PLN INIT page a

flight level lower than the current aircraft altitude, that lower flight level is not

transferred to the now-active flight plan. If the previously-entered flight level is

higher than the aircraft, it will become the new active cruise altitude, but no climb

maneuver will occur until the flight crew has raised the clearance altitude and

initiated the climb by raising the FCP altitude.

A secondary flight plan independent of the active flight plan may be built by

entering a company route (CO ROUTE) in 1L or FROM/TO identifiers in 1R.
