We were flying in and out of clouds just north of there in a piston multi-engine airplane using oxygen and my student asked if we could go do the approach into To-Hell-u-Ride for "fun". I wanted to punch him. If you lose an engine, you are screwed, because you aren't climbing at that altitude for the missed-approach. Single-engine climb (on a multi-engine) is your limiting factor for a lot of stuff.Pretty tiny. Maybe 20-30 passengers? I don’t remember, exactly. But the Telluride runway is also kinda terrifying. ends with a huge cliff.
