Now I'm confused. The RACAL report puts the best guess at the waypoint change being approx 21 seconds before impact, which is after the calculated switch off of time of the TANS. Does that make sense to you?
Can you think of any reason why they might switch off TANS if they hadn't lost confidence in it?
