The Alternation Agreement
The agreement HAL entered into with the local authorities (The Alternation Agreement) under section 106? of the Town and Country Planning Act I think is, many believe, binding.
HACAN Clear Skies the pressure group are just waiting for HAL/BAA to break it.
I'm sure that NATS can write the safety case that proves parallel approaches could operate, but until the the agreement to use one runway for part of the day and the other after will be the sticking point.
Or is all of this just amunition to prove why Gatwick and a 2nd RWY there is the only viable option?
