"William W. Plummer" wrote: Here's an explanation by a highly qualified (F-4G, F-16, and B-52) USAF pilot: " In landing the B-52 with its very long wings, it is imperative to have the wings level through touchdown, the landing "trucks" aligned with the runway, and the aircraft fuselage crabbed in to the wind. On final approach, the crew notes the wind speed and direction and, using a handy "crosswind landing chart," computes the number of degrees that the landing "trucks" must be offset to ensure they are aligned down the runway on landing. Then the pilot or copilot reaches down to a mechanism sitting between the pilots and "dials in" the appropriate number of degrees of offset for the trucks. This procedure is accomplished for EVERY landing. As I recall, normal (non wartime) procedures routinely allowed for 20 degrees of offset. More offset is possible but slightly uncomfortable for the new pilot making such a landing as he will not be looking straight ahead at touchdown but rather he will be looking toward his left or right shoulder." But, the B-52 is very, very different than civil jet transport aircraft. It has crosswind landing gear. |

In a sense it's a bit like the question of why airliners fly wings level even under asymmetric power. The best answer I heard was :"because they *can*". Julian Scarfe I believe that is true for any aircraft certified under Part 25. |

It's all crab until about 150 feet, HAT, where the autopilot goes into align mode; that is it transitions from crab to wing down into the wind with a slight amount of upwind rudder. This last throughout the flare ^^^^^^ downwind rudder, surely. CV Correct, downwind rudder and upwind aileron. If I am landing on Runway 27 and the wind is from 360 at 25, the left foot will be on the rudder and the control wheel will be to the right. ;-) |
