How good are your brakes?
The fuel load is 416,000 lbs and reject is at 174 kts. I wonder if the Airbus A-380 can perform up to this standard?
Watch this clip at the link below and see how a brand new $305 million dollar (�203 million) airplane weighing 435 tons (nearly a million pounds) carrying 64 thousand gallons (242.500 liters) of jet fuel attempts an RTO (rejected takeoff).

Just to make it interesting (and for test results) the brakes fitted are down to the wear marks (rivets) meaning they are worn out.

Full brakes are applied when the aircraft reaches 200 miles an hour and NO engine thrust reversers are used. The builders (Boeing), test engineers and designers then watch to see if, when and where the airplane will stop.... and so can you.

Well I seem to recall that an Airbus did the same thing and the tires burned. I was not an A-380. Boeing has been doing steady work on improving the 747 now going on 43 years since they introduced the airplane. The dash 8 has to be at the very top of what a good freight hauler is and needs to be.
