Yeh, the other week in a very light 75 got asked to "Maintain 180Kts for the time being" at LGW. Squealed to slow down at six and a half. Unfortunatly the a/c took so long with the throttles shut it tripped the snitch box at 500' for low pwr. They were coming up honest. Yep I thought it would have been possible from 6 miles too but not on the day. Sorry guys after that you don't get 180 inside 9 now from me as don't want another conversation with me chief.
