I know this isn't right but you couldn't be more that 180 degrees From
Programmed Heading. You'd be something less than that but in the other
direction ;').

Thanks Mike - I just realised I made a bit of a stuff up. It does
range over the full 360 degrees, and thus is just a bearing (heading)
which agrees well with groundspeed calculations from GPS. Which is not
really what I wanted to find, makes it just another redundant
measurement.

Does it actually stand for Programmed Heading or Present Heading?
(with some F word - Fly?)

cheers,
