Heya!
Left Pack:
Top Left: No function
Top Right: No function
Bottom Left: Sets a max pitch angle
Bottom Right Sets a max bank angle
Both of these are rather useless as well, as the AP of our modelling wont reach those limits anyways. But if you want to recreate real life SOP, these should be on, just wont have an effect if that makes sense.
Right Pack Top Right: Also no function
