to me, if the airspace is affected and its a code red, its abit risky to go. I mean code red is the highest alert level. isnt it?
but i've seen operators still operating into those airspace under this alert level...so i'm thinking maybe there's something that they know and im trying to, hopefully, learn a few things here.
thanks.
Think of it as a jelly fish floating in a 3D airspace. If you know where it is and is going to be when you are in the air than you can always route arround or over it. Knowledge in dispatch allows you to fly safe.
Fortunately the volcanos in Japan rarely put out large amounts of ash to shut down all airspace within a large radius of the erruption.
