Autopilot Roll Setting: "STANDARD RATE TURN"

[rfazio1951]

Here is my suggestion:

     Just downloaded version 14.0 and can't wait to try it out. I see some pretty nice things were added. One thing I was looking for that I think a lot of IFR pilots would like is an autopilot roll setting of standard rate turn. So you could set a bank angle as you do now but an added check box or at the extreme of the bank angle adjustment it would show, STANDARD RATE TURN. What ever speed you were flying at it would make a 1 minute 180, Within limits of course.

Uhhh, think it does that now. Standard rate turn up to a maximum angle that you have set.

Really! I'll try that out. I have it set to a low bank angle 20 degrees I think. So I wasn't seeing any standard rate turns.

Actually, the AP will generally seek the bank angle you set as maximum (when it needs it to make the direction change). It will exceed a standard rate turn. So as you said initially, figuring out the bank angle that equals that for the speeds you fly at will be the way to get closest to that.

Maybe I put in a maximum that worked out pretty well with a standard rate. Not the first time my brilliance has amazed me.

In an aircraft with a wide speed range, like an RV6, the speeds are all over. Im practicing approaches from 110 kts to 80kts. A standard rate turn would be nice.

Something like the TRIO EZ Pilot already has?:

A “standard rate turn” of 3 degrees per second may result in a comfortable bank angle at 130 knots, but as speed increases the bank angle must be increased to achieve the standard rate of turn.  In faster aircraft this steeper bank may be uncomfortable to some pilots and, indeed, may exceed the capability of an altitude hold system to maintain altitude properly in the turn.  To remedy this, the EZ Pilot has a means whereby the users can adjust the maximum rate of turn to their personal satisfaction.   When shipped, the EZ Pilot is defaulted to an “automatic” mode where the actual turn rate is automatically adjusted based on groundspeed (as measured by your GPS).  For aircraft cruising at groundspeeds of 140 knots or greater the automatic mode will decrease the allowable turn rate to keep the aircraft bank angle at a comfortable maximum of approximately 15 degrees.  Slower speeds will allow a standard rate turn of 3 degrees per second.

So, basically a standard rate turn to a maximum bank angle. That would be perfect.
