@ LRD its true i dont fly the 777 but i fly the 330 and have been through that area many times and the escape routes are not meant to clear mountain tops but rather to follow specific corridors that will make u clear that area and thats why position accuracy is very important to make sure that the a/c will follow that specific corridor so in reality u will be between mountains not clear their tops.the escape routes over Iran airspace are a little different u do follow the airway and the vertical profile will clear mountain tops but over that part of the Himalaya clearing mountain top is not possible at all thats what i was trying to tell u no need to be rude and state that cause i dont fly 777 i dont know what i am talking about ,if ur so concerned about it why dont u ask ur fleet to clarify and if ur still not convinced go fly somewhere where they dont fly that way ,and another thing Emirates fly that way too are they also endangering lives
