Jan 24, 2020 at 0:40 comment added Vikki To be super technical, flights have to be IFR at or above FL180 and at or below FL600 - above FL600, the airspace reverts to class E, where VFR flight is permitted (although not many aircraft are actually capable of sustained flight above FL600).

Mar 1, 2014 at 16:45 comment added Lnafziger @roe Airspace designation is left up to the individual ICAO member countries, so could be different. As you said, it it Class A above 18,000 feet in the USA (which is why I said no VFR) but it could be different in other countries.
Mar 1, 2014 at 15:57 comment added falstro Oops, didn't mean to imply anything weird, I was just wondering if there was some other rule you might know about regarding FL180 except for the fact that there's class A above it (in the US).
Mar 1, 2014 at 13:25 comment added Lnafziger @roe Well, as I said in my answer this is per the FAA and US rules. One answer can't possibly cover the legal aspects everywhere in the world. For instance, in the Bahamas VFR is not allowed at night. I'm sure that there are some countries that require IFR flights in other circumstances as well, and doubt that Class A airspace above FL180 is universal.
Mar 1, 2014 at 12:26 comment added falstro Is the FL180 cut-off international? I thought it was only because there's airspace A above FL180 (true in the US, not everywhere though). Germany has airspace C from FL100 (mostly) and up and does not necessarily require an IFR clearance, but I don't know if there's an FL180 cutoff.
