I admit I don't know the figures, but when the standard missed
approach procedure is to go round on the side where aircraft aren't
taking off, do you really think that the number of potentially
dangerous movements for mixed approaches WOULDN'T increase by
several orders of magnitude if aircraft were taking off on both
sides?
First, on what insanity are you projecting on ATC? Why would
aircraft *be* taking off on both sides?
If alternation continues on the existing runways, with mixed-mode on
the new one, this scenario will happen 50% of the time.
If martians fly out of your bottom, the National History museum will
want a word.
Unintelligible comment 1.
To illustrate the foolishness of your fear tactics, let's call the
runways Left, Right, and New. All proposals thus far have New be
much shorter than Left or Right, and is located to the north. So if
you are using New for departures to the west, you'd *also* use Right
for departures, and Left for arrivals.
Why? And likewise, during easterly operations are you saying that
09L would always be used for departures, a total reversal of the
Cranford Agreement?
Why not?
The point is simply that your scenario collapses, entirely, with a
trivial procedural change.
If you regard runway alternation at Heathrow and the Cranford Agreement as
trivial, you have a lot to learn about the realities of operating Heathrow
airport.
More realistically would be to simply sequence operations in such a
way that the runways are not being used simultaneously, but rather as
a means of reducing the in-trail separation of the traffic by
offsetting the traffic.
Unintelligible comment 2.
I would simply note that your scenario has little or nothing to do
with reality.
Yours too, I hope.
Sadly for your whining, my scenario matches what actually happens at
airports...
I don't think you understand what actually happens at Heathrow.
