6.10 HUD / AVIONICS
The horizon line in the HUD now extends across the entire HUD FOV.
If the FPM is displaced outside the HUD FOV, it stays in the HUD FOV and has an X displaced
over the symbol indicating that it is unreliable. Flight conditions such as a strong crosswinds,
extreme rudder input and high G maneuvers will cause this.
When the normal horizon line is not in the HUD FOV, it is replaced by a ghost horizon line. The
center of the ghost horizon line is on the outer edge of an imaginary circle with an 8° radius
centered in the HUD FOV. The ghost horizon rotates around the center of the circle to indicate
which direction to pull toward the real horizon.
When the aircraft is in a dive (FPM below the horizon), the dive attitude bars are bent
incrementally. The minimum bend is 8.3° and the maximum bend is 45° (at 90° of dive). Also
note the pitch ladder lines are different.
When the steer point diamond is out of the HUD FOV, it will be displaced in the HUD side of the
shortest turn to get to the STPT and will have an “X” superimposed over it.
Some minor tweaks to the AIM-9 uncaged symbology have been made. The missile diamond
flashes when the target is within maximum range and the missile reticle and missile diamond
flash when the target is within the maneuver zone (between RMAX2 and RMIN2).
