: If you are a pilot based elsewhere please write to confirm why you believe that it is important to provide facilities for general aviation and the unique role that DHA plays as the only private GA aerodrome in Greater London with convenient tube and rail links to the capital.
Just a few miles away Stapleford Airfield has been operating as a private family run GA airfield since 1933. It also has convenient central line links to the capital - so perhaps not such a unique role.
