^^^^^^^^^^^^ ^^


Didn't know ft is a metric unit (femto teslas ? :-)

My GPS is configurable, the altimeter is not unless I prize the glass
off and repaint the dial. Hence the mixed unit salad ;-)

Oh, yeah, and the 'compass rose' page, which I use going xc doesn't
show altitude, so no meters anywhere in sight in my cockpit.....
