Pseudo
waypoint Definition
Level symbol (top of climb or level-off position), when the aircraft reaches :
• The FCU-selected altitude (blue arrow), or
• The constrained altitude, if it is more restrictive than the FCU altitude and if appropriate modes are
engaged (magenta)
• It does not appear when the aircraft is within 100 ft above, or below, the selected altitude.
Top of descent symbol, or continue descent symbol :
• White, if DES is not armed
• Blue, if DES is armed.
Start of CLIMB symbol :
• White, if CLB is not armed
• Blue, if CLB is armed.

Pseudo
waypoint Definition
Intercept point symbol :
• White, if only the NAV mode is engaged
• Blue, if DES mode is engaged
• Indicates the point at which the aircraft is predicted to intercept the descent path, if there is any vertical
deviation while the aircraft is in DES mode.
• Speed change symbol (magenta) :
• Indicates the point at which the aircraft will start an automatic acceleration or deceleration from the
current speed to a new computed speed for SPD LIM, SPD CSTR, or HOLDING SPD.
Decelerate point symbol :
• Indicates the point at which the aircraft is predicted to decelerate for approach (and thus switch to the
approach phase)
• Magenta, if in managed speed and NAV or approach mode is engaged
• White, if in selected speed or HDG/TRK mode
• Automatic decelerations only occur when displayed in magenta.
ALT CSTR symbol set around the constrained waypoint :
• Magenta, when the ALT CSTR is predicted to be met.
• Amber, when the ALT CSTR is predicted to be missed
• White, when the ALT CSTR is not taken into account by the FMGS, and NAV mode is engaged.
Energy circle symbol (green arc) centered on the aircraft position and oriented to the current track line.
Represents the Required Distance to Land.
Only displayed if the lateral guidance mode is heading or track, and the current FMS flight phase is in
cruise, descent or approach, and the aircraft is within 180 nm of the destination.
(4) TO waypoint
This is the next waypoint to be overflown.

This area of the screen also shows :
• Waypoint identification (white).
• Track to go (green).
• Distance to go (green).
• Estimated time of arrival (green), assuming the aircraft will fly directly from its present
position to the TO waypoint at the current ground speed.
(5) Navaids
The display uses specific symbols for navaids :
DME or TACAN
+ VOR
VOR/DME
◂ NDB
The symbol appears :
• In green if the navaid is a current waypoint of the flight plan.
• In white if it is the TO waypoint.
• In blue when the navaid is tuned for display either automatically by the FMGC or manually
through the MCDU.
• In magenta when the navaid is not part of the flight plan and is called for display as an option
(corresponding option pushbutton pressed on the FCU EFIS control panel).

(6) Airport
Airport included in the flight plan :
• If the runway is not specified, the airport is represented by a star and the identification is
displayed in white.
Example : * LSGG
• If the runway is specified, it is represented by an oriented runway symbol in white.
Optional airport information
The airports that are not displayed as part of the flight plan may be called for display (ARPT
pushbutton on the EFIS control panel).
They are represented by a star and the identification in magenta.
(7) ILS Course (Magenta)
When the pilot pushes the LS pushbutton switch on the EFIS control panel, and if an ILS
station has been selected, the display shows an ILS course symbol.
(8) ILS Marker Beacons
The screen shows these as waypoints (diamonds).
When the aircraft overflies a marker beacon, the corresponding symbol flashes :
Blue for the outer marker.
Amber for the middle marker.
White for the inner marker.
