Thanks for the replys.
I'm just a wee bit concerned about damaging the engines, something my company would be a little annoyed over having to order 4 new GE's!!
I supoose the other concern in very low viz dust storms is the shear quantity of it that must be in suspension in the air, and again whether it would be prudent to divert rather than do an autoland?
I guess its one of those things once you have seen it once, the 'whats the big' deal issue go aways ... its the unkown ... our ops manuals give litle guidance ...
