(a)
Title line : gives the aircraft model number defining the airframe series and the engine type. This number refers to the aircraft aerodynamic model. There are 3 aero models stored which are selected by program pin (2 discretes). The displayed aero model reference reflects the pin program status.
(b)
Line 1L : displays the type of engine on the aircraft and so gives the engine model loaded in performance data base. There are 6 engine models selected by program pin (3 discretes) and the displayed reference reflects the program pin status.

(c)
Lines 2 and 3 : display the navigation data base part number and effectivity for the active and second data base. The navigation data base is stored for two successive 28 day cycles. The appropriate cycle is automatically selected using the A/C clock date, but automatic selection may be overridden by pilot selection on A/C status page.
(d)
Line 4R and label line 5R display the numbers of elements stored by the pilot. In fact, in addition to the navigation data base elements, the pilot has the ability to create and store up to 20 waypoints, 20 navaids, 10 runways, 3 routes. These stored elements belong to the active data base and depending on program pin configuration may be deleted, during DONE phase, by pilot selection of 5R key (if DELETE ALL prompt is displayed) or when the active data base is no longer effective.
(e)
Line 4L : enables the crossloading activation of the Navigation Data Base when the prompt is diplayed in DONE or PREFLIGHT flight phase. When it is selected, the ACTIVATE CROSSLOAD prompt is replaced by the CONFIRM CROSSLOAD prompt in order to enable the transfer of the Navigation Data Base from the onside FMGC to the offside FMGC.
(3) Navigation Data Base The types of data stored in the navigation data base are as follows:
-Navaid
-Non directional beacon
-Waypoint
-F-Plan fix
-Airport
-Runway
-Airway
-Holding pattern
-Terminal area procedure
-Company route
-Alternate
-Fuel policy.
Flight plan fixes may be either Navaids, Non directional beacons, or
waypoints.
(a) Navaids - Non directional beacons (NDB) Navaids and NDB are radio stations that may be used for radio tuning or position updating, or designated as flight plan waypoint.
1 The pilot may display information concerning any navaid
_ defined in data base or by the crew on the Navaid page. This page is accessed from the DATA INDEX page (DATA mode key). (Ref. Fig. 050) Data fields:
a Line 1L : displays the ident of the navaid. This is a pilot
_ entry and the page gives information about this navaid.
b Line 2L : displays the class of the navaid. It may be:
_ VOR ILS DME DME VORTAC LOC VOR DME ILS NDB
c Line 3L : displays the latitude and longitude of the
_ navaid. In case of ILS, this is the localizer position. In case of non collocated VOR DME, this is the VOR position.
d Line 4L : displays the frequency
_
e Line 5L : displays the elevation (except for VOR and NDB
_ where it is undefined and blank).
f Line 6L : displays the figure of merit indicating the
_ maximum distance at which the navaid can be tuned (except for LOC, ILS, NDB where it is blank). Figure of merit may be:
-| 0 40 Nm | 1 70 Nm | 2 130 Nm | 3 250 Nm
-
g Line 1R:
_
-
for VOR-VORTAC-VOR DME, it displays station declination
-
for ILS-ILS DME, it displays runway ident.
h Line 2R : displays ILS approach category for ILS-ILS DME
_
i Line 3R : displays the course of the localizer for LOC-ILS
_ or ILS DME.

If the pilot wants to get information about a navaid he has
created and stored, he may have access to the NAVAID page
(Ref. above) or to the STORED NAVAID page.
(Ref. Fig. 051)
Data fields:
a_ Title line : in columns 19 through 23 are displayed two
numbers.
The second one gives the number of navaids that have been
created and stored by the pilot. This number is equal to
the number of stored navaids displayed on A/C status page.
The pilot may store up to 20 navaids.
The first number indicates the rank of the displayed navaid
in the list of stored navaids.
