SYMBOL FUNCTION
a
Water line Indicates fuselage reference line (FRL). Displayed when attitude
information is not valid. Also displayed when gear down or the flightpath
marker is at, or beyond the HUD’s full field of view.
0
Heading pointer Actual aircraft heading is displayed below the stationary heading pointer.
~ @ PitchMightpath ladder
!@ Ghost flightpath marker
0 Radar altitude indicator
c9 Altitude analog dial
@ Altitude pointer
Ladder displays aircraft climb/dive angle and roll angle. Aircraft vertical
flightpath angle is indicated by the position of the flightpath marker on the
pitchfflightpath ladder. Positive pitch lines are solid and negative ptch lines
are dashed. To aid in determining flightpath angle when it is changing
rapidly, the pitch lines are angled toward the horizon at an angle half that
of the flightpath angle. For example, in a 40” climb, the pitch lines are
angled 20” toward the horizon. “Up” appears at +90” and “down”
appears at -90”.
Displayed at the true velocity vector position when the flightpath marker is
caged and the true velocity vector position differs from the caged position
in azimuth. When the true flightpath marker position is actually outside the
HUD total field of view, the symbol will be pegged at the edge of the total
FOV and flash.
Displays radar altitude when the aircraft is below 5090 feet AGL and bank
angle is less than 45’. If RDR is selected as the altimeter source and valid
radar altitude exists, the radar altitude is displayed within the dial, replacing
the barometric altitude. An R is displayed to the right of dial to indicate
radar altitude. If BAR0 is selected and a valid radar altitude exists, radar
altitude is displayed above the attitude dial or box.
The HUD analog altimeter consists of ten dots encircling the altitude
readout. Each dot indicates altitude in hundreds of feet with the zero mark
located at the top center of the dial.
An analog pointer indicating altitude moves uniformly around the inside of
the altitude dial based on indicated altitude. Increasing altitude is
indicated by clockwise rotation of this pointer.
Digital altitude readout Digital barometric or radar altitude is displayed depending on the source of
the data. When the ALT switch is in the BAR0 position, barometric altitude
is displayed. When the ALT switch in the RDR position and if aircraft
altitude is 5000 feet or lower, radar altitude is displayed within the dial and
is identified by an R to the right of the least significant digit. If the radar
altitude becomes invalid by exceeding 5000 feet or 45’ AOB, barometric
altitude is substituted and a B will flash to indicate that barometric altitude
is being displayed rather than radar altitude.
Vertical velocity readout The vertical velocity readout consists of a maximum of five digits for a
positive vertical velocity indication and a maximum of four digits with a
leading minus sign for a negative vertical velocity indication. If the limit
32,999 or -9,999 is exceeded, a minus sign with four x’s (-xXxX) is
It is displayed below the six o’clock dot of the altitude dial.
