As I understand, the 737 crew should have maintained RWY track to 0.5Nm before the threshold (coincident with the 220’ DA) and then turned right (provided they were above 600’). According to the report the turn was recorded as starting at 0.8Nm beyond the threshold (1.5km).
Now I don’t know how long it would take between initiating a roll control input and a turn displaying on a radar trace but in this case the aircraft was turning 1.3 Nm beyond the MAP while moving at about 2.5 Nm per minute.
I don’t think it even remotely fair to label them ‘muppets’ or accuse them of not following the missed approach procedure even if the turn was delayed by 20-30 seconds. Let’s not forget the ridiculous 737 autopilot disconnects as soon as you push TOGA so it’s a pretty busy period.
Not saying it was textbook but the situation was bound to occur despite the variation in reaction time. To blame the crew overlooks all the procedural issues which made this an entirely likely outcome.
