(3) Saving Flight Data. The following data
can be saved individually to the data cartridge.
1. Up to 40 alternate flight plans with a
maximum of 60 waypoints each.
2. Markpoint and User Waypoint lists.
3. GPS almanac data.
4. Fifty-two V/UHF Communication radio
presets, HAVE QUICK II MWOD, and
5. System fails history of all integrated
avionics LRUs that provide fault
status, including continuous BIT fail
results, and bus status fail history.
(4) Accessing the ICAO Identifier Database.
ICAO identifiers stored in the data cartridge are
accessed by entering the identifier into the scratchpad
and pressing a waypoint entry line select key (i.e., a
line select key on a CDU page allowing entry of
waypoints, for example, the Flight Plan page). Once
the line select key is pressed the FMS-800 searches
for the entered identifier in the data cartridge and the
user waypoint list. It searches first in the data
cartridge and, if not found, in the user waypoint list. If
the identifier is found, the corresponding information is
transferred with the identifier to the CDU (i.e., waypoint
type, latitude-longitude, elevation, station declination,
etc.). If the identifier is not found in either database,
the FMS-800 will annunciate, informing the crew that
the identifier was not found in the database.
v. System Status.
(1) Status Monitoring Overview. The FMS-
800 continuously monitors the status of each of the
avionics system LRUs. When an LRU reports a
failure with its internal Continuous Built-In Test (CBIT)
routines, a STATUS annunciation appears on the
annunciation line and the CDU alert or Message
(MSG) annunciation is activated.
The FMS provides continuous monitoring of
CBIT results of the following LRUs:
2. Data Loader.
3. GPS Receivers.
5. V/UHF Radio.
Additionally, a detailed Status page is available
for each LRU providing expanded results on both the
LRU and the MIL-STD -1553B data bus for each LRU
on the bus.
(2) Reporting CBIT Results. Results from
CBIT routines are compiled and reported to the LRU
level on the FMS Status and Navigation Status pages.
A detailed status page is available for each LRU
providing expanded results on the LRU itself and the
MIL-STD -1553B data bus status for each LRU on the
(3) System Status Page. The status pages
display the status of all the LRUs in the system and
provide access to the individual LRU detail status
pages. Checkmarks designate which LRU caused the
STATUS annunciation when a failure is detected.
The LRU checkmark is cleared when the detailed
status page for the failed LRU is accessed. Refer to
Figure 3C-138 and Table 3C-100.
