Sideslip causes one main landing gear to touch down first, followed by the second main gear. This allows the wheels to be constantly aligned with the track, thus avoiding any side load at touchdown. The sideslip method for crosswind landings is not suitable for long-winged and low-sitting aircraft such as gliders , where instead a crab angle ...
The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.
Some aircraft use lift spoilers on landing approach to control descent without changing the aircraft's attitude. One jet airliner not fitted with lift spoilers was the Douglas DC-8 which used reverse thrust in flight on the two inboard engines to control descent speed (however the aircraft was fitted with lift dumpers).
Wheels on fixed gear aircraft Wheel fairings are often called "wheel pants", "speed fairings" in North America or "wheel spats" or "trousers", in the United Kingdom, the latter enclosing both the wheel and landing gear leg. These fairings are a trade-off in advantages, as they increase the frontal and surface area, but also provide a smooth ...
By the end of the 1990s, Menasco Aerosystems was the free world's largest producer of aircraft landing gear, with plants in California, Texas and Canada. A few of the aircraft that gear sets were made for include the A-7, F-102, C-130, C-141, the Space Shuttle, F-16, F-16E, F-18, F-18E, YF-22, B-1, C-5A, C-5B, B-52, and tip gear for the B-36.

This is a mix of crab and sideslip and it is a recommendation from Airbus. Crab angle is removed before the touchdown in order to reduce the side loads on the landing gear of the airplane. Sideslip Approach. Airplane approaches the runway in steady sideslip, maintains the sideslip during flare and touch down.
