Isn't the logic of EDTO, that after a critical system failure the AOC approval requires an aircraft to land within the maximum diversion threshold of 3 hours?
Are you guys saying an aircraft can fly past an adequate or suitable airport (where it initially has enough fuel to divert to) and set course for it's destination single engine purely cause it has enough fuel?
What if the destination is more than 3 hours away and you get something like a cargo fire warning? After travelling a certain distance past the suitable or adequate airport single engine where there would then be insufficient fuel to return to the adequate or suitable airport with sufficient reserves (ie: the return suitable or adequate has a tempo weather requirement)
