I’ve been trying to get my head around the implications of your latest post and your post at #31 ER BN. My ‘take’ is that you have deep expertise in the area and you have no confidence that what’s presented in the ATSB report on the Mangalore tragedy is an accurate representation of what really happened or what the controller saw in relation to SCTAs. It my take correct?
Notwithstanding that I have no expertise in the specific ATC system displays and functionalities, it makes no sense to me that ATSB went to the trouble of recreating what ATSB represents as the display showing the velocity vectors as not intersecting at the time of what the ATSB describes as the 1122:49 STCA but decided not to recreate the display showing the velocity vectors at the time of what ATSB describes as the ‘final STCA’ at 1123:51 - immediately preceding the collision.
