How to calculate the bank angle for a specific turn radius?

Featured Replies

Are you sure about that? I could be wrong but I had always just assumed that the flight director would guide a standard rate turn up to bank limits. If it doesn't, then how decide how sharply to turn?
'Fraid not. The FD commands a bank angle proportional to the difference between current heading and set heading limited by the bank angle limit selected (max 30 deg). Nothing to do with rate 1 turns. As other's have said earlier in the thread those have to be made by skill, judgement and above all practice. The only help available in manual flight is if the aircraft has a rate of turn indicator in which case you can use that to set up a rate 1 turn exactly.Kevin Hall

Guys, listen - you really don't care about standard rate turns in day-to-day flying. I can't remember the last time in the 737, I needed to know what the standard rate was.When are you going to use it? No-gyro approaches?Just put the bank angle selector on 25 and be done with it. If you want to learn something, figure out how to build holds in the FMC. That's actually useful.

On the flight director the NGX FCOM v2 and training manual is a good start. For flying procedure turns there's some good advice in this thread from pilots.Kevin Hall
