IJ, agree fully. My local aero club spends a fortune improving its facilities for the benefit of its members and the bank runners contribute significantly to the wear and tear on the strip as their aircraft are generally larger and heavier that the little things the aeroclub operates.
Perhaps AVDATA may need to "move with the times" and look at other insitu methods of recording arrivals etc - I'm no Inpsector Gadget but sensors and digital cameras set up correctly might supplement the current RT recording method. It might also help catch those Mooneys pretending to be Boeings and so provide the airport operator with the option of taking up the issue with the aircraft operator.
Pilots who are aware of aircraft no making the correct RT calls might, as I have, make a radio call to the offending aircraft. It sure doesn't lead to "happy times" on the apron but it does protect the interests of the airport operator.
