F-15E stuck in A/A after some time

[Buzzer1977]

After some time the F-15E is stuck in A/A mode. Can't switch back to NAV or A/G and the left MFD is stuck with the A/A radar and can't open the menu.
Can't attach a track file, because they're way too large as it usually happens in longer missions.

It sounds like you are in GUNS, if you have the weapons select switch on the throttle in guns, the jet is overridden to A/A GUNS acquisition mode. To get out of it and back to normal operation just move the weapons select switch to SRM or MRM instead.
