We don't have a 45 degree downwind join in the UK.
Is there any rule or law forbidding it? Please quote official source?
Or is there a list limiting the ways one can legally join the circuit? Please quote official source?
Jan Olieslagers, if you read the whole of this thread I think you will find this has been indirectly covered in the sense that the Rules of the Air state that a) all turns in the ATZ must be to the left (unless ground signals indicate otherwise) and b) aircraft joining must conform to the pattern of traffic formed by other a/c.
I am not very familiar with the "45 degree join" but I believe a turn against the circuit direction would have to be made when joining somewhere along the downwind leg. Also if there are a/c already in the pattern you are not "conforming...etc".
I was - and continue to be - questioning the very generalistic "We don't have _____ in the UK". It seems a large assumption.
I suppose one could pose the question "Don't you have an overhead join in the USA (or any other State)?".
Whilst not technically legislation this is published by the CAA so notwithstanding local airfield procedures this is how the CAA expect aircraft in the UK to join the circuit at an airfield with no ATC:-
"Overhead" Join
When in Rome do as the Romans.
