A couple of "quick" settings, (if you don't wish to do it manually, the correct way!)
Is your Altimeter reading the correct altitude at the airfield that you are at?
Press "B" to set the correct "Barometric" atmospheric pressure at the airfield, and therefore the correct altitude!
(It is often useful to press "B" during the flight, to correct any changing atmospheric pressure during the flight).
And what about your panel Compass. Is it pointing in the right direction?
Press "D" to set the correct "Direction" corresponding to your Magnetic Compass.
