Roffa,
Understood..
Remember that I was saying that many different regulatory agencies are looking at the Gatwick model?
The FAA AC, may or may not have an equivalent ICAO, CAA, or whatever reference..I just dont know,
and while the Gatwick model works very well, there is certainly alot of regulatory substantiation behind it....
I am trying to wade through the regs, criteria, regulatory guidance, and what is circulated on a high level, as we all know, there is frequently a difference between the criteria, regulations, and actual operations.
As an example, according to the FAA heirachy, NextGen is in operating beautifully...and worth every penny of the $4 Billion dollars spent so far.
