Yes, it looks like they should have written "NM" instead of "nm".

- andkenneth 2y agoNo one is using nanometers in aviation navigation. Quite a few aviation systems are case insensitive or all caps only so you can't always make a distinction. In fact, if you say "miles", you mean nautical miles. You have to use "sm" to mean statute miles if you're using that unit, which is often used for measuring visibility.
- ianferrel 2y agoSure but I could imagine some kind of software failure caused by trying to divide by a distance that rounded two zero because the same location was listed in two databases that were almost but not exactly the same location. In fact I did when I first read the headline, then realized that it was probably nautical miles. That would be roughly consistent with the title and not a totally absurd thing to happen in the world.
- scarlehoff 2y agoThis is exactly what I thought q when I first read the title.
- anigbrowl 2y agoIndeed, but you can easily imagine a software glitch over what looks like a single location but which the computer sees as two separate ones.
- jp57 2y agoIndeed, having locations internally represented in software with a resolution of nanometers is as ridiculous as having your calendar's internal times represented as milliseconds since some arbitrary moment more than fifty years ago!
