The connection between the QF32 failure and high takeoff thrust on certain runways remains very mysterious if indeed there is any connection at all.
I wonder about some things relative to the airports and the A380. At LAX, there are two parallel runways, one (25L) is 11,095 ft. X 200 ft, the other 12,091 ft. X 150 ft.
TO on the wider runway is at 250.2° and would generally be into the wind (breeze off the ocean) but at time could be downwind (Santa Ana winds from the mountains to the east of the airport.)
At JFK, the runway (13R) is 14,511 ft. X 200 Ft. TO normally would be at 133.9°.
The LAX runway is 3,416 ft. shorter than that at JFK.
Are A380s limited to 200 ft wide runways for TO & landings?
If so, perhaps a fully loaded and fueled Qantas A380 departing LAX would require maximum thrust on TO (72K) at times, especially with an east wind blowing. TOs are always to the southwest. Full fuel loading would probably be needed to assure sufficient reserves non-stop to Sydney, head winds, etc.
Any thoughts?
