I have never flown to Deanland but have been there by car.
They were not keen on visitors, especially in "big" planes which is basically PA28/C172 or bigger
Noise / NIMBY reasons, as usual. My TB20 was absolutely banned (and anyway the runway is too short, in most conditions, for it).
The runway is short but any pilot with a PPL should know how to work out whether a runway is OK for his aircraft.
A C172 is fine for Deanland but you cannot come in at 85kt and hope to bleed the speed away gradually
You have to treat this as a max performance landing, and takeoff.
A number of people from my locality seem to have pranged their planes at Deanland.
