Question

How many horse power is required for A380 flight?

Answer 1

Well, the TECHNICAL answer to this question is:

ZERO (0, zip, nada) horsepower is required for CONTROLLED FLIGHT, as the A380 has like a 3:1 glide ratio, or something like that. Meaning, if you were a cruise altitude and shut down the noise makers, you would GLIDE 3 klicks forward for every klick you descended.  

Now for SUSTAINED flight, I would want all of the ponies that thing could put out - but you have to convert the HP to thrust weight. Mike B. did the math for you, but there ALL kinds of variables you have to take into consideration (density altitude, weight of the aircraft, weight & balance, arm & momentum, OAT, blah, blah, blah) before you can determine the minimum airspeed/sustained flight power requirements

Answer 2

As you see, the horsepower figure doesn't mean much.  The A380 is a turbojet-powered airplane, and for jet airplanes, power is not calculated in horsepower.  The significant number is the thrust, which, as mentioned, is 280,000 pounds.

Compare that to the Boeing 747-300 at 240,000 pounds, and so on.  You can find thrust figures for all common aircraft on the internet.

Good luck!

Answer 3

A380-800 has (4) 70,000 lbs thrust rated engines = 280,000 lbs of thrust.

2.2 lbs of thrust per HP

280,000 / 2.2 = 127,272.727 HP
