Second Airbus A380 takes off

Wake turbulence can be a big problem indeed.

But I wonder, does the rate of the wake increases when the airplane is heavier or when the wings are larger? Or both?

Because the A380 was/is supposed to be lighter then the 747, in that case (and if the wake depends on the aircraft's weight) that shouldn't be a problem.

Don't shoot me I'm not an expert in wake turbulence but AFAIK the heaviness of the wake depends on several things. The heaviness of the vortex depends on the loading on your wing. The loading will depend on the weight and on the shape of the wing.

But personally I don't think that the wake produced by the A380 will be much bigger if bigger at all compared to the one of the B747.

Chris,

Could be true indeed, and I'm sure the people at Airbus thought about that.

We'll see, planning my trip to Frankfurt at the moment

Of course they did. And They will try to minimize it so they can have a normal heavy separation between two planes. Let's hope they achieve this.

Have fun and make pictures for those of us who can't go

Airbus’ third A380, MSN 2, performed a successful first flight yesterday afternoon, 3rd November. The flight lasted three hours and took the aircraft over Southern France. During the flight, all systems were checked out and the whole flight envelope was cleared. The tests performed were similar to those of a serial production plane. The aircraft joins the first two A380s which, together, have already performed some 440 test flight hours in over 120 flights. These three development aircraft are powered by Rolls-Royce Trent 900 engines. The crew for this first flight comprised experimental test pilots Wolfgang Absmeier and Hugues van der Stichel, with Jean Piatek and Wolfgang Brueggemann as flight test engineers, and Bruno Bigand as test flight engineer. While the first two A380s are equipped with heavy test instrumentation, this third A380 to take to the air only has a medium sized instrumentation. After complete checks, it will fly to Hamburg in the coming days, where it will be the first to be fitted with a full cabin. It will be used for cabin and cargo systems development and certification, for the Early Long range Flights to be performed with Airbus personnel, as well as for further airport compatibility trials.
