Operations
Crew interface is accomplished through the FMS CDU and/or MCDU,
utilizing a UASC FMS with SCN 1000.5/1100.5 or later. Data may be
entered at any field highlighted by a cursor. The cursor is displayed in
the first empty data field. Fields with plus signs (+) indicate information
is required. Fields exhibiting minus signs (-) indicate input is optional.
If there is no cursor displayed in a data field, selecting the ENTER key
will place the cursor over the first enterable field on the page. Data is
then entered into the field using the CDU/MCDU alphanumeric keys.
In some situations, flight progress and related data from the FMS will
be prefilled. Subsequent presses of the [ENTER] key will move the
cursor to the next enterable field. Pressing a line select key (LSK)
highlights the corresponding data entry field. Selecting [ENTER] when
the cursor is in the last data field on the page results in the cursor
parking off of the page. Pressing [ENTER] again positions the cursor
on the initial enterable field on the page.
FMS Input
The FMS continuously provides current data to UniLink. Many
messages and requests have fields that prefill with FMS flight progress
data and computed information. In most cases the user accepts the
data for inclusion into the message. It is possible however to change a
value by overriding that value with a manual data entry. Manual entries
are generally retained until power shutdown, although data that would
normally change as a flight progresses will be cleared once the page
has been exited (is no longer displayed).
Source FMS
The crew must ensure that the FMS that is navigating the aircraft
(Source FMS) is the same FMS that supplies data to UniLink. The
Source FMS is shown on the SOURCE FMS page, accessed via
MAINTENANCE (1/3) > SENSOR STATUS > SOURCE FMS.
