The correct wording here would be that "A private key is in every
flight recorder produced so all you have to do is break into the
hardware to get it". Thank you for warning us, every badge or record
flight made by you or your mates in the future will require that the
flight recorder be sent to the IGC for inspection 8^)

That is not going to work. The same private code is used in many flight
recorders, so all you have to do is break into one and break into the
software. You then have the private key for all similar flight recorders.
Mine as you put it is still intact. It is pointless relying on a private
key of any length if you are going to put it out into the world in an
easily available box, that is not security, that is total ignorance and I
suspect the penny has already dropped with the IGC as well, took em long
enough.
Getting back to the subject of the AH here are so many solid state rate
gyros on the market, which will interface to a pocket PC or whatever that
is is a complete nonsence to ban soaring software that has ability to
display an AH. Using a small stand alone unit, smuggled into the glider in
your Glock holster would make far more sense if someone is determined to
fly in cloud. Having the instrument does not force you to fly in cloud
anyway. Banning useful software in this way is an ignorant and ineffective
thing to do, especially when the software is "Open Source" and you can
change it how you will with no-one else being the wiser.
I have managed to get two of my gyros I use on models to inteface with my
iPaq and provide a working artificial horizon so it is not at all
difficult. Anyone who would like plans forward your name on a £50 note
