-Waypoint position defined in the NAV data base is within the EDIT area.
-The waypoint is not a flight plan waypoint or the active waypoint.
-
If a terminal range is selected, the waypoint must be classified as terminal or terminal/enroute.
-
If an enroute range is selected, the waypoint must be classified as enroute or terminal/enroute.
(2)
NAVAIDS (VOR.D) When the navaids pushbutton switch option is selected all NAV Data Base VOR and/or DMEs and all stored Navaids that meet the following criteria are transmitted as map background data.
-Navaid position defined in the NAV Data Base is within the edit area.
-
The navaid is one of the following types: . VOR only . DME only . VORTAC (collocated or non-collocated) . VORDME (collocated or non-collocated) . TACAN . DME part of ILS/DME (collocated or non-collocated).
-
The navaid is not selected to be output as a tuned navaid.
For non-collocated VOR/DME and non-collocated VORTAC two symbols are transmitted, one for the VOR (at VOR location) and one for the DME or TACAN (at corresponding location).
(3)
Nondirectional beacons (NDB) When the nondirectional beacons pushbutton switch option is selected, all NDBs in the NAV Data Base that lie within the defined edit area are transmitted as map background data.
(4)
Airports (ARPT) When the airports pushbutton switch option is selected all airports in the NAV Data Base and all stored airports that meet the following criteria are transmitted as map background data:
-
The airport position defined in the NAV Data Base is within the edit area.
-
The aircraft is not the origin or destination airport.
(5)
Waypoint constraints (CSTR) When the waypoint constraints pushbutton switch option is selected all speed, time and altitude constraints for all flight plan waypoints excluding the FROM waypoint are transmitted as map background data. Note that navaids, airports, and nondirectional beacons may also be waypoints in the flight plan, therefore constraints will be displayed for these. If an altitude window constraint exists, both altitudes will be displayed with the AT OR BELOW constraint displayed directly above the AT or ABOVE constraint.

EIS DISPLAYS - DESCRIPTION AND OPERATION

A. Overall Architecture and Operation
(Ref. Fig. 001)
The Navigation Display (ND) is derived from:
-the flight plan data
-data selected via the Flight Control Unit (FCU)
-dynamically changing data such as aircraft present position, wind speed
and direction, ground speed, track. The Flight Management (FM) data transmitted to the ND are divided into two groups: dynamic and map background. Each EFIS control panel on the FCU enables selection of the display mode, the display range and various display options. The following modes can be selected: ARC, ROSE-VOR, ROSE-LS, ROSE-NAV and PLAN. (Ref. Fig. 002) The range selections available are 10, 20, 40, 80, 160 and 320 NM. If either mode or range data from the FCU are invalid, then both default mode and range selections of ROSE-NAV and 80 NM are used. Terminal area ranges are defined as 10, 20, 40 or 80 NM. Enroute ranges include 160 and 320 NM. The various pushbutton switch display options available are waypoints, navaids (VOR.D), non directional beacons, airports, and waypoint constraints. The next paragraphs detail the edit areas associated with the selectable modes, the available display symbols, the pushbutton switch options and their display rules, and the flight plan displays. The system response time is defined to be the time elapsed between when the modification is inserted via the Multipurpose Control and Display Unit (MCDU) and when the associated word group is transmitted on the EIS bus.
