A question concerning a recent change to the missed approach procedures in Dubai UAE (OMDB) has raised some interesting points about the 777 in this flight regime: high thrust, low altitude, high pilot workload, and ATC procedures that would seem to be not too well thought out.
Specifically the new procedure introduces a not-above altitude of 1300 ft AMSL after going around from a near sea level Precision or GPS approach minimum (1000 ft missed approach climb).
This new procedure initially tracks straight ahead from the Missed Approach Point (MAP) (that’s a good thing) to DB710 – but requires the crew to level off at 1300 ft AMSL (Not so good). It then requires level flight for approximately 3nm (why? why?)

That's for 30L ......... doh!
Also, as said, notamed and removed quickly.
