This, but the reason it's engineered that way is because landing gear face far higher loads on landing. During takeoff, landing gear essentially only have to support the weight of the aircraft. During landing, the gear have to arrest the aircraft's descent (which may be momentarily 3 or 4 g's of acceleration if the aircraft encounters turbulence while landing); and then they need to brake the entire weight of the plane within the remaining length of the runway, which is a high loading in a different direction (along the aircraft's longitudinal axis). So maximum landing weight is set by the landing gear, while maximum takeoff weight is usually set by the wings and engines.
- eric_h 8y agoI didn't realize that most of the braking on landing was handled by the landing gear. I'd always assumed that the obvious sound of the engines reversing when we landed did most of the work, but some casual googling suggests that it's only supplementary, to reduce the load on the landing gear.
