> It's specifically only trying to be a font for cockpit displays. On that front, there isn't really a context where I and l would be ambiguous in context.

So for example IATA and ICAO airport codes are not within the context of an airplane cockpit?

And the visual difference between "laa" and "Iaa" doesn't matter?

The first one is Lamar Municipal Airport, while the second one is Igarka Airport.

In those cases, they always would be in caps.

So you get LAA and IAA, which are indeed distinct in the typeface.

Nevertheless they (and most other typefaces) should have avoided the ambiguity.

you are having too much of good faith in always-perfect assumptions when it comes to life-critical systems. I hope you are not involved in developing or designing such systems.
