Then there are a big mistake in the Pushback procedure ( the Walkout assistant HAS NOT to ask the Captain to release the Brakes ) which
will also not be changed.
I never said it won't be changed, I always tried to get a precise, complete, explanation on how, in your view, the Pushback procedure should be changed, but I never got a clear answer.
Without even mentioning that, if you search several aviation forums where real life ground operators post, and it seems that each time somebody post his own version of the pushback procedure, he always starts with "I do pushback at the xxxx airport, everybody that posted before got it all wrong, we do it this way", and it's a different version of it so, it's clear that it's not the same across different part of the world and airlines.
But if you send me a PRECISE description of what changes you would like to see, we'll consider it. Yes, you sent me a PM a while ago, but I didn't understand it very well, because it was a bit confusing the way it was written.
