so...5*75000*(84.5^2) equals 267759375 or 26mj...well off!
Dry runway, sea level, no wind, no THR REV.
Err, small arithmetical mistake there...
0.5*75000*(84.5^2) equals 267,759,375 or 268MJ
70*4=280 - that "70MJ" brake rating wouldn't happen to be "per brake" by any chance? If so, it's pretty close for a four brake case.
