F4-BMS 2.0 Technical Manual
when the steerpoint selected is 40 nm away. It may often be used with IR Mavericks where target
coordinates are not known in advance. Another application of SP is for weather avoidance (not
implemented).
Additionally, the GM range AUTO bumping function is revised in this version. It works more
intuitively now with the range bumping up if the cursor is at 95% of the way up the MFD and
bumping down if the cursor is at 42.5% of the way up the display or less. Note the bump will only
happen if and when the cursor is not being slewed! As a final note, TTG (Time-to-go) has been
added to the GM radar scope when you are in STP mode or SP mode with a ground stabilized
aim point.
Added the missing BATR (Bullets at Target Range) circle for EEGS. It is a 6-mil circle displayed
after the trigger squeeze and the bullet travels the target's range. It disappears after the last bullet
passes the target range (well actually it disappears 1 second after the trigger is released--that is
good enough for the time being). The BATR is nothing more than a record of where the gun
cross has been pointed (corrected for gravity drop). Needs some refinement, but the basic
functionality is there.
The EEGS funnel will now disappear when the trigger is pulled and reappear 1 second after
trigger release.
"X SRM" or "X MRM", where "X" is the number of missiles for that type, are now drawn in missile
override mode (instead of "MSL"). "MSL" is a display thing of BLK 30 F-16s and lower (i.e.,
mainly older software tapes).
Mach number and max g's windows are now not drawn in the HUD when in Dogfight override.
The "SpeedText" (basically the CAS [i think, but doesn't really matter ;-)] speed required to reach
the current steerpoint on time) field is now not drawn in the HUD when in Dogfight override. This
was never realistic.
Attack symbology (missile reticles, ASEC, ASC, DLZ, timers, etc) are blanked on the FCR/HUD
when the master arm switch is in OFF (i.e., weapons safe).
The bar scans (the number of bars in the scan, rather) was incorrect for both ACM 30x20 and
ACM Slewable. 30x20 was corrected from a 5B to a 4B and Slewable was corrected from a 3B to
a 4B.
TMS aft is the only switch action that commands a break lock from an ACM track mode.
Added center-point dot to the gun strafe circle.
Adjusted STRAF in-range cue line to work when within 8000 feet (instead of 4000 previously) to
accurately reflect in-range cue for GU-28 bullet instead of M56.
Minor fixes to HSD symbology to reflect proper size (0.05 is DEFAULT/OFF and 0.025 is half-
size, i.e., ON). We recommend 0.025 for 1600x1200 resolution and 0.035 for 1024x768.
Tweaked ACMI colors/labels a bit to be a little more readable.
