Funny thing is is that no one has yet overshot the B into B9 turn at the other end (admittedly not used very much).
Actually I think there have been a couple, but they just taxied into C10 and back via the international apron so there wasn't any hoo-ha with tugs and pavement issues
. The worst thing they copped was a ribbing from the tower.
If an A380 did it it could get a bit untidy, but IIRC they can now use the L/P turning loop. If I've got that wrong they'd possibly need to get towed back, but unlike TWY Delta the pavement is still rated for their weight so it would just be an inconvenience.
What about 'follow the greens' like they have in SIN and LHR amongst other places?
How does that work?
