There are a lot of assumptions one could make when designing data types and schemas for aviation data that turn out to be inaccurate. In the spirit of Patrick McKenzie’s classic piece on names, here are some false assumptions one might make about aviation.
Thank you for the learning! Before this thread, I didn’t know enough about altitude to care about this question, but now I’m like “neat! Cool learning!”.
On a similar vein, there’s indicated airspeed, calibrated airspeed, true airspeed, and ground speed. Aviation comes with a hard requirement of 5th grade math.
