 Aircraft symbol
Fixed aircraft symbol indicates position of aircraft relative to the horizon.
‚ Roll Scale
The scale is graduated at 0, 10, 20, 30 and 45 bank degrees.
ƒ Roll/Sideslip Index
Upper part of the index indicates current bank. The lower part moves below roll part and shows amount of side slip.
„ Pitch Scale
Graduated each 2.5 degrees, indicates current aircraft pitch.
… Attitude Limits
Green ‘=’ symbols are displayed at ±67° on roll scale, at 15° nose down and at 30° nose up on pitch scale. They represent the
pitch and bank limits of Normal law protections.
† Radar Altitude
Radar altimeter readout is displayed when below 2500 feet AGL. At low altitudes, the white line which separates pitch scale and
solid bottom part, moves up as aircraft gets closer to the ground, covering the pitch scale, and meets the horizon line at touchdown.
Radar altimeter readout turns yellow when below DH, if it was set.

Guidance
Flight guidance commands generated by FMS are depicted by Flight Director
(FD) symbols. Flight Director system allows the pilot to manually y the aircraft
while following the guidance commands. The FD symbols are only visible when
FD button on EFIS control panel is illuminated.
There are two different modes of FD operation, with different symbology. The
displayed FD symbols corresponds to selection of HDG-V/S or TRK-FPA mode
on the FCU.

HDG-V/S Mode
In this mode, the FD symbols include two bars. Vertical
bar indicates commanded bank, and horizontal bar shows
commanded pitch.
To follow the commands, steer the aircraft so that the bars
cross at the center if static aircraft symbol.
In this example, a left bank and present pitch is commanded.
TRK-FPA Mode
In this mode, the FD symbols include a ight path vector symbol and a ight path director
symbol. Flight path vector symbol (“Bird”) represents the aircraft vertical ight path angle, drift
angle and bank. The command symbol (“Moustache”) shows commanded ight path angle, as
vertical distance between the symbols, and roll, as the difference in symbols rotation.
To follow the commands, steer the aircraft so that the two symbols are aligned.
In this example, a left bank and pitch up is commanded.

ILS Indications
When ILS receiver is automatically tuned for destination airport approach by FMS, or ILS frequency is manually entered on MCDU
Rad Nav page, the localizer and glideslope deviation bars can be displayed on PFD. To do so, push the ILS button on EFIS control
panel. Second push removes ILS information from PFD.
 Localizer deviation ‚ Glideslope deviation
ƒ ILS front course
 Localizer deviation
‚ Glideslope deviation
The magenta indexes represent horizontal and vertical deviation from localizer and glideslope. In this example, the aircraft is to the
right and above the glide path. When a deviation diamond index reaches a limit of a scale, it turns to magenta arrow.
ƒ ILS front course
Magenta dagger on heading scale indicates the selected landing runway ILS course, or course manually entered on MCDU
Rad Nav page.
