The RAF compass has tooltips only for the heading selector ring (increase/decrease click-spots) and lacks the actual readout tooltip of the current heading. The Luftwaffe one has both, the increase/decrease functions when you mouse over it close to the center and the current heading when you mouse over the rest of it.
In the Bf-110 or Ju88 for example, i just mouse over the magnetic compass before take-off to see the tooltip, then input that into the gyro-compass.
In the RAF aircraft i have to move the view around a bit which is not a big problem, but i don't know how to read the compass
A small workaround for the RAF compass is to align the heading selector with the compass arms and read-out the selector's value. I then open the map and look which way i'm facing on mission start (this needs map icons to be on though), so i can discard the reciprocal heading of my current one. So, if i align it and it says 270 while i'm facing east, i know it's 90 degrees. I then turn the gyro-compass to read 90 degrees and start my take-off.
It would be much simpler if it had a tooltip or i actually knew how to read it
