      Another bug regarding the F-18 MPCD (see my bug report on the ILS needles https://www.benchmarksims.org/forum/showthread.php?31916-Bug-ILS-Needles-wrong-in-F-18-MPCD-and-ADI&p=446161&viewfull=1#post446161). It seems that for some reason needles in this instrument are mirrored or rotated from where they should be. When I fly directly (straight) towards a TACAN station at a magnetic heading of e.g. 214 and select a course of higher than 214, say 230, the deviation bar should be on the LEFT of the course arrow (since I need to fly to the left to intercept that course line). In version 4.33.3 of the F-18 it is on the right however and moves to the left when a course of less than 214 is chosen. I only tested this for the TACAN mode, but I am sure it is also broken for the NAV mode to waypoints. Could somebody check please?

      EDIT: the same bug occurs also in at least the AV-8B; other custom cockpits might have the same issue. Since the ILS bars in the F-18 in the same instrument are also bugged, could it be that a certain LOD transformation matrix has a sign flipped?
