I'm not involved in aviation these dayd, though I worked for the UK's NATS many years ago in operational research. I haven't even been on a plane since 2017! So I tend to lurk here, and approach interesting questions from the point of view of general engineering.

Any code of mine that I publish anywhere on stackexchange.com I hereby place in the public domain to the extent governable by law. Explicitly, I place it under the CC0. This also applies to documentation/instructions etc.

Opinions I post are mine and mine only unless clearly stated.

Attribution (especially if I say anything clever) is appreciated where reasonable - but specifically not demanded.
