The wing you do not want to change either, except for winglets and changing the flap configuration, as anything structural requires a full re-certification, including static and dynamic load tests.

I do not think they are planning to fly with the blocks on the wings, so bending relief is not an issue. Forces in the wing on the ground can only be lower without weight on the pylon. I think tying...

Then just fit the raked wingtips as the last item, when it is outside the door. They should be line replaceable anyway.

Parking on (or actually in) aircraft carriers is at a slightly higher premium than at most international airports. Also these short range aircraft with a thrust to weight close to one have ejection...

Having one retract and the other not will always cause a lift asymmetry. If it doesn't affect the aircraft at all, you might as well just leave the entire wingtip off in the first place.

Where the comparison with the 747 flap system goes astray, is that the folding wing folds in the direction of the main force (up) where the track system folds in the direction of the wing cord (and...

Even new technology cannot go against the laws of physics. Parasitic drag rises a lot after Mach 0.8 and decreases again slowly after Mach 1, but still stays higher than below Mach 0.8. The only...

East London (AMS, which is the main intercontinental hub for the UK population living outside the London area) is now also at a capacity limit, so competition should not be so fierce.

This surprises me. I'd expect foam and especially powder to require a removal. With Halon or CO2, being almost inert gasses, I would not expect much cleaning to be needed at all.

Note that Halon...

A quick fuel and crew change stop, keeping the passengers onboard, would be a much more economical option. This would probably add 1 - 1.5 hours to the trip.

I think the main problem with ULH is not the extra fuel itself, but the payload reduction to take that extra fuel. Also the extra crew (at full pay, weight and needing rest areas) is another big cost...

On a two leg journey, you will probably also be flying at a higher cost index, thus faster, as conserving fuel is less of an issue. Next to this ULH is more likely to go over the (north) pole, which...

With one engine shut doen and the other at idle, I think the pressurization system would not be very effective.

The Lden noise contours (with the same traffic) will be almost identical with mixed mode vs. closely spaced parallels. ATC will surely prefer segregated runways, as workload will be lower and...
