You have data from a training session. It has a recording of many
aircraft movements that you can play back. Perhaps you add one new
and controllable craft to the mix (AAL460 above?) and that's the one
that gets vectored by the trainee, to see what kind of trouble he can
get in/out of. Since all the other aircraft had been affected by wind,
the controllable plane needs the same flight input. Is this a good
description?

If so, I'm thinking that the wind within the 2000' block you talked
about, is a single fixed value for the entire training session. Would
that be fair to say? If that is true, then you don't need to
calculate the wind except once at the beginning. Can this be stored
for later use each time?

Hey, Kev. We're not going to be adding tracks, we'll just review what
was done with the existing aircraft. The real kicker is that the
operator can effectively take control an aircraft and "fly" it
according to an alternate set of instructions the controller could have
given the pilot. We can then watch the original track of the aircraft
alongside the simulated track and see how the situation would have
developed if the controller had made a different choice.

The playback has no idea what the winds are. If we don't account for
the winds, the simulated track for an aircraft would behave as though
the wind was calm, which is highly unrealistic. Since this is a short
time frame and a relatively small chunk of airspace, a single
calculation for winds would be fine.
