I've never seen ASDA>TODA, perhaps as
J_T suggests, it may exist in rare circumstances. From my point of view, if the ASDA surface is good enough to stop the aircraft upon, then it's certainly good enough to fly over, and TODA should at least equal ASDA.
J_T quoted "
All limitations must be considered separately.".
I'm in total agreement, being a very unbalanced individual, but be aware
J_T, there's a certain VERY BALANCED individual lurking "out there" in the desert dunes, who will reduce TORA, TODA, and ASDA to
ONE figure for his very balanced operations. I can just imagine him right now, at the keyboard, signing in, just got to mu....., standby for incoming
