Second attempt to post this question in the ATC forum. It was moved to the Tech Log...Did I do sth wrong the first time around I wonder?
Within your TMA, what is the longest possible procedural route in track miles that an a/c has to run (from entry point to FAF)?
On the same note, how large is your TMA (in sq miles)?
The Athens TMA definately needs redesigning, with the new airport that is now situated to the north of the old TMA boundaries. Flactuating altitude block restrictions from the Tanagra airbase to the NW practically force all arr/dep procedures to be run from/to the south-southeast. For a/c arriving from the west (eg NEMES) for a 21L arrival, this can mean as long as 130 track miles crawling around at TMA speeds (240KIAS below FL240!). ATC are doing their best to keep it quick and safe but airlines are winging, as they would like to be kept high(-er) and fast(-er) this far out, for fuel, turb comfort etc.
Just wondering what the situation is elsewhere...
Cheers
