Please note that the 1000' gate is a vertical profile gate and it does not require you to be aligned with the c/l. Similarly for the "hard" 500' gate.
NW1, This is hardly a general rule is it? This is up to the operator to specify or are you and Rainboe flying for the same operator? I know of several operators, including the one I fly for, that prohibits the pilots to perform any major turns below 1000 feet. In essence it requires the flighpath to be lined up with the landing runway in my case.
