In the Peel Group's Airspace Grab document they state:
The ATZ extends to a radius of 2½ nm from the centre of the aerodrome up to 2000 feet above aerodrome elevation. The airspace within this ATZ is also Class G although pilots must obtain permission from ATC to enter the ATZ. In the local area there is a profusion of GA activities associated with Sandtoft airfield, which also has an ATZ, located only 7 miles from Robin Hood Airport Doncaster Sheffield. Other airfields in the vicinity include Gamston, Sheffield, Sherburn-in-Elmet and Netherthorpe embracing myriad aviation activities. Moreover, there are numerous gliding and microlightssites plus parachuting takes place at nearby Hibaldstow. The nearby military airfields of RAF Waddington, RAF Coningsby, RAF Scampton, RAF Cottesmore, RAF Cranwell and RAF Barkston Heath generate considerable traffic, much of this operates at low level. The Lincolnshire Area of Intense Aerial Activity (AIAA) is situated to the south of the Airport and the Yorkshire AIAA is to the north. In summary there are a multitude of disparate aviation operations in the area and this is now further complicated by the ever increasing operations from Robin Hood Airport Doncaster Sheffield.
Actually, it just indicates that it was a stupid place to put a new airport!
They also state:
The plethora of flying activities described above taking place in uncontrolled
airspace has led to a number of safety-related incidents which together with the illustrations of predicted growth underline the pressing need for a revision in the airspace arrangements.
But they haven't substantiated their claim that 'a number of safety-related incidents' have occurred with any examples.
I have also been told that they are planning an increase in training movements - including RAF - and other ways of increasing their commercial development. Although that is supposed to be 'rather hush hush for the moment'. Clearly the intent is to say "Look how busy we are - we really need all this Class D airspace we've asked for!"
