Welp, it's a failure because the capital "i" does not have crossbars... making it indistinguishable from a lower-case L.
Such a tiresome defect in one font after another.

On the other hand, putting crossbars on their I would make it much more visually similar to their 1 glyph. Mixing I and 1 (again, in waypoint names, for example), is much more likely and the strong visual difference in I and 1 by not having crossbars on the I seems like a better choice for the stated goals/applications of this font. ("...improve the display of information on the cockpit screens, in particular in terms of legibility and comfort of reading, and to optimize the overall homogeneity of the cockpit")
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.
So you get LAA and IAA, which are indeed distinct in the typeface.
Nevertheless they (and most other typefaces) should have avoided the ambiguity.
