In addition to the comments already made I have two pet hates.
Firstly, why cant pilots give accurate circuit position reports? What is wrong with “early” or “late” downwind without having to search for someone along the length of the downwind leg? “Downwind turning base” or “base turning final” come to mind as other examples. It might not be standard phraseology but you certainly know where to look.
Secondly, why do some pilots insist on parallelling a circuit leg when departing the field? How many times have you been downwind to see another aircraft wide of and parallelling you at circuit height - is he or isn’t he in the circuit?? It cant be that hard to fly at an obtuse angle to the “parallel” circuit leg even if that means a slight correction once well clear of the ATZ - can it?
Finally, I am a passionate believer in tight circuits BUT circuits are like clothes - they need to suite different occasions. Some smart arse flying a tight circuit is not what we are looking for when there is 10 in on a sunny April day and there are a few dusting off the cobwebs not having flown all winter, a couple of students and the odd new PPLer. It might not be ideal but it is safer and more “gentlemanly” to adapt the circuit to suite the circumstances.
