(i am not a flight expert but a phd student in economics and i am studying these flights for a research project I would be very thankful for any relevant input!) background The soviet and chinese airspace was very restricted during this time and few airlines were granted. Yes, i still get to fly in an aeroplane with triple delco civa installation They are old, extremely bulky and heavy but the perform really well In a nutshell, all the navigation computer needs is barometric altitude and tas from the cadc (although is perfectly capable to operate without them) and present position input for alignment.
