|Quoting Blrsea (Reply 4):
There were lots of threads on this. The flight path doesnt go over the himalayas. It goes over central asia ->Afghanistan-> pakistan ->India. It doesn't have to go over himalayas
Correct. The flight path usually crosses the Hindu Kush over Afghanistan, and that has never been a problem for any plane.
As for Himalayas, there are restrictions on flying across Tibet in general, irrespective of how many engines you have, because in case of cabin depressurization it is impossible to bring the plane down to 7000' without going a few thousand feet underground
. The plateau is about 11 to 12 thousand feet average altitude. This is obeyed quite carefully. For example, last time I flew SQ
we flew an almost straight route across the pole, except for a divergence to the left to avoid a corner of the Tibetan plateau.
BTW, flight that originate or terminate in Tibet of course fly over Tibet. As a matter of fact when I flew from Lhasa to Kathmandu the aircraft was a twin (757) which flew right over Mount Everest. Can't get any higher than that, and yet it was a twin.
