In the military, when a system on a piece of equipment was thought faulty, the air crew/ user/ pilot/ driver would fill out a VIDS/MAF (Visual Information Display System/Maintenance Action Form) stating what was wrong with the system and turning it in to Maintenance Control. Control would then send it out to the specific shop to fix the problem. When the technician went out to the aircraft, ran up the FLIR/Radar/ACU system and could not duplicate the problem or found no errors, they would sign off the gripe sheet with 11-1-A-799 (at least in the airwing that was the full line/box codes) and send it back to Control meaning that we couldn't duplicate the problem and they were full of crap.
We just sent back two MAF's A-799'd on those two down jets. I don't know what the pilot/RIO/B/N was thinking or doing wrong, but we tracked targets fine. Maybe they really CANT hit anything and needed to blame it on the aircraft. See if you can get flight ops to put Wiley up in her next time, betcha he won't gripe the tracking system!
