Big airplane, lots of weight. Notice that the big guys have a HUGE
difference in their takeoff weight compared to their max landing weight. So with spoilers, they kill off the excess lift while making use of the drag of the flaps (excess lift becomes an issue in ground effect). This lessens the load on the gear as they touch down (as opposed to the solo student slam down ;-) ). And if they really have to stop, I'm told they don't touch the brakes until after full reverser deployment (I am assuming here that from their touch down speed of 120-180 knots, they kill off 30-50% via reverse thrust). But, I'm still learning and I may not have all of this correct. But it is how it all appears to me in thinking about the physics involved. Later, Steve.T PP ASEL/Instrument
