well
i have to say i have just completed some work experience at birmingham airport and spent a day with the atco's.
some of the light aeroplanes that fly through the controlled airspace can cause problems or disruption to the positionig of commercial aeroplanes and it really does anoy the atco's. they told me that they aim to provide an outstanding service to commercial aeroplanes and light aeroplanes alike but if a light aeroplane is disrupting the path of a commercial aeroplane then that aircraft will have to move because there are paying customers on the other aircraft and it is not a leisure flight. and i saw for myself the actions taken by the pilot of a light aircraft whilst trying to land on runway 33
believe they do work hard up there
