How many main landing gears does an aircraft generally have?

Aircraft typically have three main landing gears, which consist of a nose gear and two main gears located under the wings or fuselage. This configuration is common for a variety of aircraft, from small general aviation planes to larger commercial airliners.

The importance of having three landing gears lies in achieving stability during takeoff, landing, and while taxiing. The nose gear supports the front of the aircraft and aids in steering, while the two main gears distribute the weight of the aircraft evenly and provide the necessary structural support during ground operations. This three-point configuration enhances balance and control, especially on uneven surfaces.

While some specialized aircraft may have different configurations—such as those with a single landing gear or four main gears—three is the most common setup for a wide range of aircraft types. This design also simplifies the landing process, providing a more stable platform for recovery after touchdown.
