There's another thread where an instructor opines that SEPs following a glideslope of more than 3-4 degrees may become unstabilise.
The thrust of the post encourages pilots to use a 3-4 degree final - am I alone in thinking that this kind of arbitrary advice (nonsensical IMHO) could also contribute to bomber circuits? since you only descend about 300 fpm on a 3 degree G/S and even a 600 foot final turn (lower than many would choose) would equal 2NM final.
