Did I hear correct the MAS offical say the following?
Final ACAS transmitted at 1:07
Pilot's final words to ATC saying "aright, goodnight...." at 1:19
ACAS sends reports at 30 min interval so it would've been before 1:37
As such ACAS got tuned off within 30mins of 1:07 ie. 1:07 - 1:37 so could be after
As such no confirmation that ACAS was switched off before Pilot's final words.
