Yes you are correct. Its what the doc uses normally. But in circling its a little bit different.
Radius arc of protected area is :
bla bla bla ....
bank angle : 20 degress or 3 degrees/sec, whichever requires less bank.
Anyway with Airbus I can conclude its up to the FMGC and in boeing its up to the pilot? =)
This leads me to another question. Do you as a boeing pilot use this bank angle settings??? Do you change to other angles than 25???
