Using Database (Db) Fpa; Using Default ( Def) Fpa; Using Manual (Man) Fpa - Honeywell GNS-XLS Operator's Manual

Using Database (DB) FPA

The GNS-X database contains Flight Path Angles associated with
LS
waypoints on SIDs, STARs, and Approaches, that prefill when these
procedures are programmed into the Active Flight Plan. The FPA
field on the VNAV WAYPOINT Page displays (DB), which indicates
an FPA from the database is loaded and Vertical Deviation is provid-
ed at the programmed angle when the waypoint becomes the Vertical
TO Waypoint. If the FPA at the (DB) VNAV waypoint is changed in
any way, the (DB) FPA will no longer be available.

Using Default ( DEF) FPA

The default FPA value will automatically be displayed if an altitude is
programmed on the VNAV WAYPOINT Page, except if the FPA
comes from the database or the VNAV WAYPOINT Page was
accessed using a Direct To function.
The pilot can load the Default
FPA (set on the VNAV
DATA Page) by pressing the
ENTER Key when the cursor
is on the FPA field of the
VNAV WAYPOINT Page.
The FPA field displays (DEF)
and Vertical Deviation is pro-
vided at the programmed
angle when the waypoint
becomes the Vertical TO
Waypoint. (Figure 3-127)

Using Manual (MAN) FPA

The pilot can type in a desired Flight Path Angle on the VNAV WAY-
POINT Page within the valid range, 0.1 to 6.0 degrees. When the
ENTER Key is depressed the FPA is loaded, the FPA field indicates
(MAN) and Vertical Deviation is provided at the programmed angle
when the waypoint becomes the Vertical TO Waypoint.
