Just watched a BBC program on the beautiful Everest ..
Base Camp is at 5365 I am sure I heard the guy said. Damn hihj comes to mind ... and I can have a look in the books on Monday ... not the ideal hover hight for a Mi-8 / 17 (T/ MT or MTV) for that matter ...
cpt .. believe me even at 2000 metres (ok we are normally close to MAUW ) and temp much, much higher .. she does not like it ....
John, a Mi-17 is normally a military one but you get a lot of civillian Mi-17 as well. The big difference is if she was a T model or the rest.
T model is an absolute disaster to fly - no power at all - but I doubt if they would ever take a T model up there !
I think an Alo II / III still has the height record (was when I was a student in 79 anyway) .. 36 000 odd thou .... not for me tx ... I hit 12 000 and was

scared
