Crosswind crab
I’m an old BUFF driver from the ‘70’s. In that time frame we were restricted to airfield with 300 ft. width runways. The crosswind crab system was never contemplated as an aid to turning sharp corners, or taxiway maneuvering, but permitted us to land in 45kt direct crosswinds. The crab setting is precomputed and applied when aligned for takeoff, and removed when slowed to taxi speed after rollout. I had a copilot apply the setting in the wrong direction once. He saw his error, and cranked it all the way the other way while we were rolling. A thrilling low speed rudder dance ensued, similar to the video.
