Having read all the post, it makes me very worried that BA can carry so little fuel that a Go Around can cause a MAYDAY due fuel shortage. I am an ATCO and for what ever reason things do go wrong, Go Arounds occur ( a couple of times per day).
Imagine if every aircraft in the London TMA was flown in the same manner. Somebody calls a MAYDAY, we break aircraft off the approach to accomodate it. How many aircraft behind would also call?
I think Anitgua did the right thing and asked for a bit extra.This forum has high lighted a problem. It is the BA Management who are being MORed. (And/or the CAA if they allowed the SOP.)
I'm glad this subject has come up, unfortunately ATCO's cannot get near the flightdeck these days, so unfortunately we have to have these debates on this forum rather than face to face.
