How High Is Super High (ATC Sectors In The U.S.)

I've recently come across listings of enroute ATC sector names and frequencies for American ARTCCs. I've been wondering if there's a way to tell what kind of altitude each type of sector covers. I imagine the exact value varies from center to center and maybe sector to sector, but some ballpark figures would be nice. So what kind of altitudes/FLs are typical enroute sectors in charge of, e.g.:

Low
High
Super High
Ultra High

Well, not exactly sure, but I know that low is is class E airspace from 0 - 17,999 msl and high is class A airspace from FL180 - FL600. I'd assume that above 60,000 would be super high as that's where the airspace reverts to class E, but I couldn't even begin to guess where "super high" begins.

Something like 98% of all air traffic is usually handled at FL410 and below in the US...almost everything above is military or bizjets  Smile I wouldn't be suprised if the definition of "super high" begins at FL420.

Is FL230-240 usually (always?) the divide between low and high?

Low sectors at ARTCC's are, typically, FL230 and below (excluding TRACON airspace). Highs are FL240 and above. Super Highs, where they exist, are FL350 and above. I have never heard of Ultra High's. This, of course is not set in stone. When I worked at Washington ARTCC, My Area had two Low sectors (Casino-51 and Kenton-53) that went from 80 to 170. I enjoyed working those two sectors. They were fun. I was never a fan of the High's. There was a lot of: "How are the rides?" and "Can we get direct?"

Cool. By the way, I'm assuming that the Low sector controller is also in charge of the class E airspace below 18,000, including any V airways?

Thanks! I saw Ultra Highs under the Cleveland ARTCC.

I'm not sure of your question, if an aircraft is in that airspace, the controller is working him.

Yeah that question was a bit redundant, it's clear now.
