But with engineering we almost always have safety factors. I'd say it's probably a 64-bit int, but that would be way too much of a safety factor.

Safety factors are a thing, sure. Safety factors of 4.29e9x (which is what you get when you go from 32- to 64-bit ints) are possibly a bit excessive, and not at all worthy of an FAA airworthiness directive.

  • My biggest surprise today is from learning that critical aircraft software is left running for days without a full restart. Somehow I assumed everything gets completely shut down every time they refuel or so.

Given this appears to be used in the communications layer of the system I expect that the width is a defined segment of some part of the wire protocol.
