Airbus AoB significance
Hi,
Anyone know the significance of 33 and 67 degrees? I know they correspond to 1.2 & 2.6 G.
Cheers.
ps I have used the search function!

Just a guess:
33°=30° (rec max bank angle in CommAirTransport)+10% margin
67° bank angle limitation due to max g-load limitation in clean config (+2.5g).
EDIT:you need to detail your question...I understood that you wanna know why these exact values instead of others like e.g. 35° and 65°...

Flight control laws.
In normal law the pilot can bank to 67deg. If the stick is returned to neutral the aircraft will roll out to 33deg AoB.
Dont know in what context this is relevant

Shortfuel you understood my question perfectly well so there is no need to edit it. I noticed you edited your post after warren9 made his. He evidently did not understand my question at all. Good stab at an answer, thanks.

Nobody said that waren9'answers were incorrect...but regarding OP question, they are just irrelevant here.
About g-load in a level coordinated turn:
n=g-load
φ= bank angle
n= 1/(cosφ)
33° # 1,2g
45°= 1,4g (edited )
67° # 2,6g
...
Btw, bigbob, you'll find an answer in Supp Techniques Flight Controls part for the 67 degree limitation. The reason is clearly indicated.
