So now we are to have multiple for circuit patterns for differnt classes of aircraft !!!!!!!!
You got it. Look at Kemble!
I had a very well known and highly experienced examiner with me who concured with my view completly ... indeed even got on the radio to give the other pilot a bit of a licking !!!
A wonderful example of poor RT discipline, not exactly the mark of a highly experienced examiner!
Microlights need a different circuit height and pattern to most other aircraft, why should a microlight pilot even understand a larger aircraft's circuit requirements? The pilot has probably never flown one. Once upon a time engine failure in Microlights was a high possibility and their circuit was designed to keep them in a position where they could always make the field. If you are going to circuit fly at the same airfield as other traffic separate arrangements are essential. Ignorance and shouting at them on the radio is not going to produce a safe flying environment neither is expecting them to do a bomber circuit.
