777's can switch runways as easily as a smaller jet. It's the carpenter...
Misd I don't disagree, and in reference to the US, many of the parallel runways are by design a lot closer together than later designed and constructed airports. The issue is as I've said, when you aren't expecting it, it's a challenge and a threat, it's also worth remembering operating manuals differ greatly, I cannot sidestep below 1500 AAL as where I work that's considered an unstable (unsafe) approach...even if it's perfectly possible and reasonable to do so for someone else.
To be fair to ATC in the US, they give a lot more leeway to foreign operators and in my experience they help far more than hinder, but just as it can be a struggle for foreigners in the US, there's many a time I've watched and heard a delta, American or a Connie mess up something that to me seems a perfectly simple and reasonable thing to do.....so it's more the wood you are given to work with..not the carpenter my friend.
