Avoid the ash at different FLs?
Hi all,
Massively interesting reading your thoughts on all this. Quite a range of opinions, but all well-informed, which makes a nice change from the front pages of the tabloid at least!
My question that I haven't really heard is this: the ash is mostly at quite high altitude, right? Couldn't the airlines therefore simply fly beneath it? I do realise that because of the increased density at lower FLs this would require greater fuel to generate greater thrust to overcome resistance, and would therefore be more expensive... but would it be prohibitive? Would the ATCs be set up to deal with this?
Apologies if this is a stupid question, or well answered elsewhere.
Cheers all.
