Anyone done a SOIA for real?
0.86 it is pretty basic.
1.US has a plethora of closely spaced parallel runway pairs, and when the weather clamps, approaches effectively operate on one runway rather than two, hence halving landing rate.
2. Possibility for building more runways is remote, partly on cost grounds, but mostly on environmental ones. Delays can only get worse, and although US carriers are mostly affected, global longhaul operators have a stake.
3.FAA/ NASA have developed a new approach monitor radar with good accuracy and high scan rate, but even so the best that can be realised in the presence of "blunders" by the lead aircraft is a safe separation of 3400ft. This is limited by the time lags in the controller recognising the blunder, transmitting to the trailing pilot and his respone.
4. The FAA rsponse to this is to introduce SOIA withits limited benfit 9 lowering allowable cloud base to about 2000 ft from an VFR value of 4000ft. I was merely seeking any experience form the sharp end.
5.I am convinced that the only long term solution to this problem is a pilot centred operation using the technologies that I cited.Unfortunately I don's see FAA going in this direction
