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 “nonconformal
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 nonconformal
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 nonconformal
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.
Additional marks are displayed for 45 degrees and 60 degrees position when the roll angle
exceeds 32 degrees. The roll scale return to the normal format when the bank angle decreases
below 28 degrees.

SlipSkid
Indicator
The slipskid
indicator is displayed in conjunction with the roll pointer. The top of the pyramid
represents the roll pointer while the base of the pyramid is the slipskid
indicator. The slipskid
indicator moves laterally in relation to the roll pointer to indicate lateral acceleration.
When an engine failure is detected, an additional slipskid
indicator is displayed below the Flight
Path Vector (FPV). It also appears when simulating an engine failure by seperating the thrust
levers at or below altitudes of 20,000 feet; simultaneously, one throttle has to be below 3 degrees
and the other above 8 degrees.
The slipskid
indicator can only be displayed when the airspeed is greater than 80 KIAS, and in
weight off nose wheel condition.
Low Bank Limit Arc
This symbol is displayed on the roll scale to indicate that low bank Flight Director mode is active
and is limiting the airplane to a bank angle of 17 degrees.
