Absolutely.
With the “instrument heads-up display - chase cam” assistance option on, third person view shows a combination of heading and the “rim” part of an AI/Gyro that shows the current bank angle in the upper left:
(The bank angle indicator between the compass and current heading value)
When checking the ATTITUDE_INDICATOR_BANK_DEGREES value at each notch, most airplanes report the standard 10, 20 and 30 (though getting the timing to query 30 right is a bit tricky because MSFS changes the pink line into an overshoot arrow to indicate a steep turn). For example, the value I got for the above screenshot was -0.3482167339966261, which converts to -19.95 degrees.
When using the Top Rudder, which doesn’t really have anything going for it in terms of instruments, we still get that same (part of the) AI in the third person HUD:
And querying MSFS for the bank angle in the second screenshot shows a very different value, returning -0.13993549688029197, or -8 degrees. Somehow, MSFS knows what to show “if this plane had an AI/Gyro”, and in order to show the same bank angle indicators remotely using simconnect, I’d like to know how I can (either directly or by deriving it from other values?) show that same kind of “this plane’s steep turn is at X degrees, the aircraft is currently banking at Y degrees” information. The second part is nice and easy, the first part not so much?
