The interesting question is why the Max. Energy RTO was done at 575t. Was this 6t increase over the TCDS 569t MTOW done to show a margin or is another small MOTW increase planned?
Bit of lateral thinking here.......
569t MTOW was to restore mission capability lost by the 5t "overweight OEW, why test at 575t?
On its own, the extra 6 t might not gain the A380 much, but IIRC, Airbus have said that the Glare2/Al-Li A380F derived improvements I mentioned earlier sholud be available from c. frame 100 onwards.
If those improvements recover say, 4t of the original OEW "overweight", an "improved" 575t A388 might well end up with the capability of carrying an extra 10t (6t + 4t) more fuel for a given payload than the 569t "full mission capable 8 000Nm" A388.
i.e. the "max pax" fuel load could go up by c. 4%.
c 4% of a nominal
8 000 Nm range is...... 300Nm.
Is this a way for Airbus to defend against the "short" 748i, by providing the capability to offer EK
the same 8300Nm nominal
range of the shorter 748i in an "improved" 575t A388?
As well as defending against the "short" 748i, it might just give Airbus the capability of offering something to EK
actually value, as a negotiating tool to minimise the financial damage from EK
's compensation claims....
Lateral thinking or wishful thinking? Don't know, but there's a certain logic..........
