The example in the original question:
1000-lb a/c = 453.59 kg
60 knots = 30.87 meters/sec
So kinetic energy equals 216,080 joules. The conversion between heat and energy is pretty well fixed-- is it roughly 4.18 joules to a small calorie? If so, 52 kilocalories (do they still call them that?) have to be absorbed, mostly by the brakes. Enough to heat 10 lb of water 11.4 degrees C.
