Re: [CNN interview 12/8] Emirates wants Airbus to build a new version of A380

The primary load case on wing is upwards bending moment. Hanging heavier engines only helps to reduce that primary load(assuming same MTOW) What is also not being stated is the more efficient engine will have a lower fuel fraction, and thus lower weights and lower fuel burns for a given sector, thi...

Re: [CNN interview 12/8] Emirates wants Airbus to build a new version of A380

Since the A380 was developed, there has been just as much fuel burn reduction on the airframe side as the engine side in my opinion and I'm an engine nut: 1. Wingtip treatments 2. CFRP wings. This is a huge deal vs. the 777x, A350, and 787. 3. Electrical subsystems (maintenance cost reduction and c...
