selected and actual speed - * limiting and operational speeds

 -
selected and actual altitude

 -altitude barometric correction setting
 -vertical speed - * mach number - * radio altitude and decision height - * final approach trajectory deviations (ILS or R-NAV) - * marker indications - * AFS mode annunciations.

 configuration.

 (b) ND indications The ND format shall have five selectable operational modes and shall display the following parameters :
 1 3 ROSE modes = ROSE-ILS, ROSE-VOR, ROSE-NAV
_ In each mode the following information shall be provided :
 -aircraft heading and track heading dial, (oriented "heading up" with the aircraft symbol in the center of the display)
 -speeds (GS, TAS)
 -wind data
 -ADF/VOR bearing (on selection), and corresponding station characteristics (ident or frequency), plus DME distances if a VOR/DME or DME station is tuned.
 Weather radar information may be superimposed in the front
 sector.
 Course selection and lateral deviation shall be provided in
 VOR and ILS submodes.
 A map with the actual flight path and flight plan information
 shall be provided in NAV mode.
 Additional data including constraints, waypoints, NAVAIDS and
 airports may be selected.

 2 ARC mode
_ R (Ref. Fig. 006) The following information shall be provided :
 -aircraft heading and track (oriented "heading up" with the aircraft symbol at the lower part of the display)
 -map with actual flight plan and flight plan information

 -speeds (GS, TAS)

 -wind data
 Weather radar information may be superimposed.

 1EFF : ALL 1 31-00-00Page 13 1 1 Aug 01/05 1 1 1CES 1 Additional data, including constraints, waypoints, NAVAIDS and airports may be selected.

 3 PLAN mode
_
 -A fixed area plan oriented "north up", centered on a selectable waypoint, shall include actual flight plan, flight plan information and aircraft position.
 -Additional data including constraints, waypoints, NAVAIDS and airports may be selected.
 4 chronograph function
_ In any of the ND operating modes it is possible to display a chronograph function operated by a dedicated pushbutton switch provided for each pilot.
R (2) Electronic Centralized Aircraft Monitor System (ECAM) R (Ref. Fig. 007) The ECAM system comprises the following equipment :
 -
One upper display unit for engine/warning display

 -
One lower display unit for system/status display

 -
One ECAM control panel

 -
Two Flight Warning Computers (FWC)

 -
Two System Data Acquisition Concentrators (SDAC)

 -
Two MASTER WARN (MW) and two MASTER CAUT (MC) lights.

 -
Two Cockpit Audio Loudspeakers (CAL)

 -Three DMCs common with EFIS
 The ECAM system provides the crew with

 -engine primary indication, fuel quantity on board and flaps/slats position indication - operational assistance for both normal and abnormal aircraft system
 configurations. The ECAM system performs appropriate presentation on the two display units devoted to ECAM. In addition the ECAM system generates aural and visual warnings. The aural warnings are transmitted by the Cockpit Audio Loudspeakers. The visual signals are transmitted by the DU messages and the MASTER WARN and MASTER CAUT lights.
 (a) Upper display unit
R  (Ref. Fig. 008) In normal operation, i.e. without DU failure, the top two thirds of the display will present engine indications, plus fuel quantity and flaps/slats position indications. The bottom third will present :
 -either MEMO messages, i.e. a reminder of functions/systems which are temporily used (e.g. APU running).
