No the range will decrease if you lose power on one engine aswell because of the added drag penalty (must reduce altitude plus having rudder trim and a windmilling engine)

But that is a different phenomenon compared to why four GE90s will decrease the A380 range. Heck it might even be more economical to operate the A380 with 3/4 GE90 engines running Grin

Hence the tri-jet idea. Tongue

Losing power probably reduces range even if there is no rudder trim, like losing centre engine on trijet. Reducing altitude should make range worse.

But does adding power, and thus reaching higher altitude, add range or decrease it?

I've heard that the A380 can fly from London to Sydney. Is it true, or is it just hype?

Yes It can with a lighter payload.

The A380 CAN fly from Sydney from London nonstop. The A380 CAN'T do it with much of a load, making it not very profitable to do so. Boeing needs to chuck more fuel into the 772LR or Qantas needs to order the long range A350 variant, but that is doubtful because they've already ordered 50? 787's.

Renember, a Qantas 744 flew from Sydney to London, but that dosn't mean you'll see it happen commercially.

Talking about long-range variants, Airbus has flown A380 at over 590 ton TOW, more than 30 t overload. The freighter (which no one but UPS wants) is to have 590 t MTOW and an extra fuel tank in wingbox.

It seems to me that once Airbus has developed the extra strengthening for Freighter landing gear and wings and the extra fuel tank, they could derive the 380-800 HGW variant.
