Not trying to be offensive, no one, but how much time have you actually spent flying in and out of non-controlled aerodromes?
My experience may be atypical, but I have:
- never joined crosswind when a high performance aircraft happened to be taking off at the same time
- never *arrived* at a height greater than 1,500' above the aerodrome (unless my TOPD and descent calculations and management have been inaccurate and poor ...
)
- never joined downwind or dead side when an aircraft happened to be departing overhead.
There's lots and lots of nothing going on out there at non-controlled aerodromes, punctuated by the occasional flurry of entirely mundane and easily manageable activity. That includes places like Mildura, Wagga, Broken Hill, Kalgoorlie ....
And don't confuse the CAAP for requirements.
