BOAC, having checked your profile I see you fly for Astreus.
In my experience you guys fly faster than anyone else
Is that on the 73 or 75? (when I was at AEU it was 290-340 on the 75
)
Just out of interest, do you ATCers take into account the wind up high? (as this makes a big difference to the profile) or is it a case of looking at the mode S MCP speeds, and comparing it to the G Speed ?
