Thinking about the BA 747 that temporarily lost all engine power after flying into volcanic ash near Jakarta, and the AirTransat A330-243 that ran out of fuel near the Azores, yet both landed safely (the BA 747 after engine power was restored), I have been wondering if (heaven forbid) the same situation was to happen to an A380. Does the A380 have any Ram Air Turbine and would this provide sufficient amount of hydraulic and electrical power? Could an A380 sustain a glided flight lasting over 10-15 minutes?

I'm not an engineer, but I'd bet that if the aircraft were at cruising altitude that it would at the very minimum have several minutes of glide capability. I don't know if she'd be capable of a semi-controlled landing, but it would be an interesting piece of trivia to know the true answer. My gut feeling, drop the nose a little and let her soar! Now where's the nearest stretch of straight pavement?

The A380 has the basic theory of flight & should be able to be glided in for a landing in the event of all four engines failing. If not, then the JAA/FAA would demand that the be a back-up engine be installed in the event that all four engines fail.

I don't think it will have any problem gliding. It may not give you the longest glide of an airliner, but enough to get down safely. Any aircraft I have flown (not that many) has a listed max. glide speed in the POH, I'm pretty sure the A380 will as well.

Yes, like any airplane with a high Lift/drag ratio, it will glide pretty far; multiply the altitude and the ratio and there you go.
The wing of A380 was designed for the larger stretch version (whenever it flies -- as opposed to the 747 which has it's wing and then got revamped over the years), it already has glider capablility well above any other powered machine.
The latter I supposed.

As the guy who came up with the 380 idea on a paper napkin after doing acid all night with some Apache Indians.... I designed a special "flame out" kit for the plane. It mixes the methane gas from the crappers with an outside RAM air, and blows an enormous torch out the rear apu outlet. This enables the craft to blissfully power up while the dwarf mechanics sleeping in the wings awake and head to the "engine room" to get they' fix on! All the while the happily bungling pax in the mile high rooms never have a clue!

I remember reading in Tech/Ops that heavier aircraft actually glide better than lighter aircraft, because the increased momentum more than offsets the higher wing loading. The A380 should be able to glide as far as most other large jets, maybe farther due to its mass, low wing loading, and advanced airfoil.

The A380 will be able to glide for about 30 minutes, covering a distance of 110 miles from a starting point of 35,000 feet. Like many aspects of it's performance with the engines turning, it outperforms the 747 by about 10% in this regard.

I've also heard people say, prior to the Air Transat A330, that the A#30/A340 could not glide, lucky for those passangers that they were wrong. The only way to tell is if it happens and of course we don't want that.

Are people on this site "player hating" on the A380? Give Airbus a break. They built a magnificent piece of machinery. It's their time to shine and enjoy their 15 minutes of fame. Someone always seem to find a fault about the A380. It seems like alot of people here want it to fail. This could only mean one thing: The Boeing fans are scared.
