eeeehhh, no....sorry ....I don't think so.
As a matter of fact I AM in a position to judge.
At 4 NM and even with a
VERY strong headwind component on a B737 on final app you are talking of aprox. 2-3 MINS to the threshold.
AND EVEN if that's the case you are looking for trouble, as you are relying on 3 pilots, 3 planes and a lot of other factors with no surprises.
And any safety management system, or manual for ATS operation, or safety case, that tells you is OK to launch THREE a/c when a jet a/c l is at 4NM on finals should be brought to a court of room straight away charged with attempted mass murder, and convicted to be hanged by their covers...
And good luck trying to find one that states such an insanity.
