IMHO in the event of an engine failure/fire en route the flight deck have enough on their minds dealing with the drills without then thinking of drift down levels at or below MSA. Equally in the event of rapid decompression the need to reduce altitude to a point where most pax would not require oxy whilst dealing with the emergency and thinking of terrain is another unwanted problem for the pilots.

As to routing the point I was making was that in order to reduce the risk of driftdown into MSA the flight planned route would take you over the track with the shortest distance to clear the high ground. Now if ATC wanted you to route differently or if wx was on the optimum flight planned route then the flight deck would have to take the risk of exposing themselves and the aircraft to greater risk to comply with ATC or to avoid wx.

That is why I argue that the aircraft is starting to be operated on routes it was not envisaged being used on.

Talk to Horizon Air, they operate -400s over both the Rockies and Cascade ranges, and have been doing so for about 2 years.

Or to any of the Western Canada operators of other Dash-8 models which have been flying the high country (and in regular iffy weather) for at least a decade.

Pitot Heat---I'm not arguing with the gerneral drift of your argument,but drift down really isnt a problem providng the aircraft is at normal height---for the sake of a figure, above 210. the distances involved are enormous and easily make the Zurich-Milan bit no problem fron this point of view. The depressurisation case however needs more thought.

Soblena,
Youve taken the time to correct I commend you:ok:

However wot as you described is spelt "what"............:hmm:

Now I have heaps of typos in my previous, but hey you understood yeah?

Take Care my friend and read some more pages of that Oxdforn Pocket Dictionary.


Adios Senior Soblena

Sheep guts,

I'm curious as to how your Dash 8s can have "build dates in 1978" when the type didn't make it's first flight until June 29, 1983.

Oh dear Guts , I was really only trying to correct you tongue-in-cheek, hence the ironic use of "wot". Ah, typos, the greatest excuse for poor spelling :hmm: Sssh, by the way, your reading isn't much better - it's Sobelena! And who told you I was Spanish and male???
