HUD SYMBOLOGY
Aircraft Symbol
The aircraft symbol represents the direction in which the the airplane longitudinal axis is pointing.
The symbol is similar to the aircraft symbol on the conventionnal ADI and has a fixed position on
the display.
Flight Path Vector
The Flight Path Vector (FPV) indicates the airplane track and path angle. The FPV is displayed
when the airspeed is greater than 80 KIAS or the nose wheel is off the ground.
The FPV symbol has priority over all other symbols except the guidance cue and the warning
indications. Other symbols in the immediate vicinity of the FPV will therefore be masked.
When the aircraft path is such that the FPV should be displayed in extreme positions or outside
the display limits, the FPV position will not be fully representative of the aircraft path. The FPV will
therefore be “non-conformal and displayed in dotted shape. However, in all conditions, the relative
position between FPV and horizon line will indicate correctly a level flight (FPV on horizon line), a
climb (FPV above) or descent (FPV below).
NOTE
In a Slat out/Flap 0 landing configuration, the high pitch attitude
during the flare may lead to a non-conformal FPV. The actual path
angle may be higher than depicted by the combination of FPV and
Horizon.

Pitch Tape
The pitch tape consists of a horizon line and a pitch scale which is centered on the aircraft symbol.
When read in conjunction with the aircraft symbol, it indicates pitch attitude. The pitch scale is
displayed in accordance with the selected IRS and is removed when the source is invalid.
The pitch scale consists of a tick mark every 5 degrees and is limited to +/− 90 degrees. The
negative pitch mark are displayed as dashed lines. The 0 degree pitch mark is replaced with the
horizon line. The small vertical lines at either side of the pitch line always points towards the
horizon. The pitch scale is removed when the airplane is on the ground and appears when the
nose wheel is off the ground.

Airspeed VSPEED Bugs
The VSpeed (V1, VR, V2, VFTO, VREF) bugs and labels are displayed in relation to the airspeed
tape.
Horizon Line
The horizon line is conformal to the external scene; however, it will appear above the natural
horizon at high altitude due to the curvature of the earth.
During very high or low pitch attitude, a non-conformal horizon line is displayed as a dashed line.
The horizon line is displayed as wide as the combiner to reinforce attitude awareness during low
visibility approaches or when the airplane is in excessive pitch attitude.
Roll Scale and Pointer
The HUD roll scale consists of tick marks at 0, +5, +10, +20, and +30 degrees displayed above
and centered to the airplane reference symbol.
