PPrune Radar,
If this extensive standard turns out to be permanent (which I doubt), the economic penalty. it will be argued, should be borne by the A380 operator. Along the lines of the 'significant economic benefit' argument.
Those operating Medium / (Normal Size) Heavy will argue they should not wear the delay.
The jealousies or economic rivalries will mainfest themeselves beyone the maturity one would hope for in an aerospace industry, but what one would anticipate in an airline industry. Remember Concorde? And it's first forays in to the US?
If you are lucky enough to have parallel runways the solution is obvious and easy (assuming a dedicated DEP RWY in use).
Not sure how often that will be the case however.
As mentioned elsewhere, US/EUR - Boeing / Airbus politics will be a factor as well.
