777 engine test run

[7neophyte7 30]

Yes, it's just the park brake holding the aircraft. There are chocks near to the wheels but not right up against them. The 777 has 12 mainwheels and each are fitted with multiple rotor carbon brakes, there are 6 pistons on each brake pack operating at 3000psi. I'd have to measure the diameter of the piston to calculate the force but they are at least an inch so that would give 14137lbs on each brake at least

 

OMG, incredible. Thanks for the info.
