Why don’t planes fly over Tibet?

Who know about this? Very interesting


It is just too high of a mountain I think


Interesting article and a good read. Makes sense that they might not be able to get below 10000’ for breathable oxygen.


Breathable oxygen actually stops around 15,000ft msl. That makes a pretty shallow corridor for airliners to be cruising around in in case they lose cabin pressure. The reason airlines don’t fly over Tibet is simply because airlines don’t want to take those kinds of risks.


If you arent allowed to fly over tibet why is there an airport there: Daocheng Yading airport


It’s not that they aren’t allowed, it’s just that going over Tibet is not the safest route for airlines to take.


Oh, sure thanks for the info! :)

Highest mountain in the world is only 27,000 feet-ish


I love how the link is an article (blog?) with the answer contained therein, yet I register maybe one stray post which even hints the poster might have read the material.

For those that prefer to guess rather than simply click, I’ll summarize the author’s point for you:

Airliners have about 20 minutes of Oxygen in the passenger cabin. Regulations stipulate you must be able to reach 10k MSL (an altitude which can’t be reached in “large swaths of [the area]”) before the Oxygen runs out. Combine MSA in the area with a large area where you can’t satisfy regulations, and a finite supply of Oxygen, and you have the author’s answer.

[I am summarizing the author’s explanation, not providing my own, but note that, right or wrong, it’s a little more specific than “thar be hills.”]

The broader point, however, is that consistently, especially in this category and those pertaining to flight in IF, we get reply upon reply atop reply of just random musings, with no citation other than “I think…” I know there are some young ones here, but I know they at least start teaching about sources and citations in school. Right?

I know it’s too much to expect citations meeting the stringent standards of peer-reviewed journals, but is it too much to ask that before simply tossing something out there, you find a citable source for your statements? Especially if the discussion centers on a link provided for you. Reading a relatively-short blog post is not, I think, too much too ask before simply spitballing.


@Tim_B… MaxSez: I note the"The Broader Point" paragraph which should be a stand alone Topic! It’s often difficult to separate the wheat from the chaff from the responses on this Forum. It’s frustrating, one liners nonsense by guess comments apparently are a barometer of the oblivious knowledge base & recognized personality quirks of our resident bloviators. Bottom Line: Before you post; Engage Brain, Research (Google is your friend), Formulate the Response, Jot. Just Sayin… Regards Tim


Correction: (29,000feet-ish) or (FL290<)


There might be a flight restriction

Read the article. It’s not that


Mount Everest is 29,029ft tall. If airliners were to cruise right over the peak, they would only have about a 11,000ft window of space. Interesting way to put things into perspective…
