One more question on A320, if you don't mind.
At one of airfields our company flies to, published minimum MACG is 5%. No mountains there, I don't know why exactly is it so high.
Let's assume that approach climb gradient, calculated by performance app in the EFB, or extracted from AFM tables is exactly 5%.
Now in case we go around one day and one engine fails, at what altitude should we accelerate and retract flaps?
Missed approach procedure tells us to climb to 3000 ft AAL, MSA is 2000 ft AAL there. But everyone leaves ENG OUT ACC height at 1500 ft. Doesn't seem right to me.
