I think that some of the ATCO`s who`ve replied have no clue what kind of action it takes to yank a large aeroplane travelling at a speed of , say 450 kts TAS around a 90 degree corner at more than rate one.
No offense, Hugmonster, but even if there is such a thing as a large turboprop

, it is a lot simpler to do your thing in that then in a large transport jet.
If you are travelling at 450 kts TAS ( which is kinda slow in cruise), it would take about 45 degrees of bank, only to make a rate one turn! If an ATCO expects more than rate one, he would thus expect me to yank my boeing around at more than 45 degrees bank! That`s 2G`s at 450 kts. Get real!
Someone from Tech log will hopefully calculate the exact amount of bank required to make a rate one at 450 kts.
