Landing Gear. The landing gear or undercarriage of an acft consists of main and auxiliary units

The landing gear or undercarriage of an acft consists of main and auxiliary units. The main landing gear contains two landing gear units, one under each side of the fus or one under each wing. The aux unit is located either under the tail or the nose of the acft.

A typical landing gear consists of three retractable landing gear assemblies. Each main landing gear is equipped with a conventional air-oil shock strut, a wheel brake assembly, and a wheel and tire assembly. The nose landing gear is equipped with a conventional air-oil shock strut, a shimmy damper, and a wheel and tire assembly.
