Hi All,
There's a couple of cheap i2c compasses available, and I'm thinking of making a compass for use in an aircraft*. On the face of it, the project is very simple - a PICAXE, an i2c compass and an LCD display to show the heading.
However in an aircraft, you are tilting in the turns and pitching on climbs and descents, and I wonder if this generates an error the non gimballed compass reading? If so, would it be possible to use some sort of solid state rate gyro to correct this?
Thanks in advance for any comments!

* don't worry - it needn't be attached to the aircraft power and it is not going be relied apon for navigation!
