It looks very very big aginst the SomesetSomersetyside and the hills around Frome. Any one know whknowseight they do these low levlow-levelts at . Having lived near LHR for years i am pretty good at guessing height of LHR arrivals but hey in a nice predictable straight line its flat. Do they have a mandatory 'floor' of say 500ft agl or 1000 asl?
Interesting contrast on the second pass when it just made a deep swooshing sound and appeared almost immediately while 6-7000 ft above an A400 was much noisier
The minimum height is 250 feet msd. Minimum separation distance - ie 250 feet in any direction.
