[BUG] Calibrating heading/altitude indicator resets themselves

[gaboroszkar]

When the heading indicator is calibrated with the mouse, turning the knob for the first time, it works perfectly, but when the aircraft turns after calibration, and then the user tries to recalibrate the heading indicator, it jumps back to the incorrect heading, which was the last heading just after calibration.

Example: aircraft is calibrated to heading 360° with the knob, then the aircraft turns 90° to the right. Then, the user realizes, the the correct heading should be 80°, so he/she turns the knob, but as soon as he/she starts turning, the heading jumps back to around 360°.

Also, it happens with the altitude indicator too, if the B (auto calibrate AMSL pressure) is pressed. And also if D (auto calibrate heading) is pressed.
