I always start on the ground, starting airborne doesn't require all this mucking about with boresighting the mavs but I prefer it.
I'm probably not explaining this properly but hopefully this illustrates what I mean;
Pic #1: Steerpoint 1 selected, TGP as SOI and TMS Down to CZ. Mavs set to PRE.
Pic #2: Square marker points to steerpoint 1.
Pics #3 & 4: Then when I press SP once the TGP moves over to this point here, which doesn't correspond to any of my steerpoints, nor is it pointing directly forward as it did before the patch.
Finally pressing SP a second time returns the square box to steerpoint 1, as if I'd pressed CZ again, see pic #2.
