The font has a slashed 0 for use in alphanumerics and an open 0 for use in numerics. There's discussion of it in other comments here.
I imagine pipes aren't used beside uppercase I in cockpits.
The odd serif on the 1 is to ensure it degrades correctly at low resolution.
When you design for safety, you also have to ask "safety in what context". It's neat that they released the font with an open license, but they didn't design it for anything other than Airbus cockpits.
