I'm sitting here in my dining room, in front of a computer and having a hard time decoding this:
"So ‘left downwind’ simply means downwind, on the left of the runway, when viewed from the direction of downwind. Which will always be the the case with a RH circuit, and a LH circuit will always have right downwind".
At my home airport there's a clear definition of left/right downwind/base. I dearly hope I'll never find myself controlling an aircraft near an airport using this (sorry IMHO bonkers) system !
