Tim may have other concerns, but one problem is that secure flight
recorders use a private/public key signing mechanism (e.g. DSA). An open
source development project could not expose the private key. However I
don't see why this automatically makes this impossible in principle,
there could be schemes where a private key is held in escrow and not
disclosed even to the developers. The developers and hardware
manufactuer would also have to organize to have software releases IGC
approved.


Do you mean secure in the sense of not being able to tamper with a
signed, downloaded trace without it being easily detectable?
