Hi T-C
I am pretty sure the ASU at Warton are still on the AS355 ( my slip saying AS350) I am trying to find out if there is any way that height can be correlated to the footprint, there is a guy at Clitheroe has a new 109, the CPL fly's it at about a fixed 2000ft and you can hear that machine for minutes before he passes over, but the one that got me thinking was the AS355 to which my first post referred, then again I suppose 500ft and a pretty fast flight may keep the footprint down quiet a lot, not looking to complain, just stretching my thoughts a little.
T-C I hope that you are well, and still chasing motor bikes
we had an AS350 with us two weeks ago, what an incredible machine, didn't know such things could be done with these birds!
