Comment on Why don't compasses have just two Cardinal directions (North, East, -North, -East)?

Btw, magnetic variation is pretty significant in some places. It’s 13 degrees where I am.

What’s the new one? I must have missed the presentation. Probably because I wasn’t invited.

I don’t remember where I watched the presentation. I think it might have been one of Brian Schiff’s videos, but I don’t remember. Here’s a link to it I found online. www2023.icao.int/safety/OPS/…/Truenorth.aspx

I suppose it makes sense but it feels wrong. I’m so used to having and using magnetic but that isn’t a reason to continue doing less efficient things.
The redundancy aspect is there as when systems would fail (GPS for true), the magnetic redundancy would still come into okay and still work enough to get by.
