April 5Apr 5 The current speed cue on the FDAI is reversed. The yellow ring indicates the relationship between current speed (yellow ring) and commanded speed (center horizontal line) This can be seen in: Commanded speed is 313 knots with an indicated greater than 313, probably 315 or so based on the speed cue on the FDAI, each wide horizontal line indicates 5 knots. Next The Roll command director will disappear off scale when in heading mode and the commanded roll is maximum It appears the Roll commands a 30° bank angle But a standard rate turn in a transport category aircraft is a maximum command of 25 degrees. Thanks, Mike
April 6Apr 6 Staff Hi, the command bar is known as well as the FDA. As for the commanded bank, the industry standard as far as I am aware is 25-30 degrees in the bank so I'll need some sort of reference regarding Tristar and Operational Limits in regards to banking. Thank you

Thank you You are correct that the industry standard is 25 OR 30 degrees. As with all things it depends. Here are all the references I could find to banking and the FD in the AOM
