I guess we are all using the same Real ATC recording from the 1st post on this thread.
From the recording it's unclear why EVA 15 made the left turn northbound, but lets assume for sake of argument that the controller did indeed make an error and issue the left turn the EVA crew confirmed. However, as soon as the controller saw them turn left she issued an unequivocal correction:
SoCal Departure: „..turn right, turn heading 180.„
EVA 15: „Copied, right heading 180, EVA 15 heavy.„
SoCal Departure: „..please expedite your right turn.„
EVA 15: „EVA 15 heavy, roger just passing heading 010, continue right turn heading.„
Pretty clear to me.
But for whatever reason, they didnt continue the turn to 180 as instructed but appear to have maintained their 010 heading setting up the conflict with Air Canada 788 and getting ever closer to terrain.
Why are we blaming the controller?
