Do you think this is going to be an Airbus directive for us all on the A320 then? I operate out of the busiest single runway airport in the world (Mumbai doesn't count!). The A320 is by far the most common aircraft to operate in and out of the airport. If every A320 has got to do a 30sec run up for half of the year then the airport is royally screwed. How on earth can this work?
We haven't been doing that for 30 years of A320 operation with the CFM so why now all of a sudden. Is that the reason for every engine failure?
