Weight on wheels (WoW) switches indicate whether the weight of an aircraft is resting on its wheels. This information reveals whether the aircraft is airborne or on the ground. WoW switches are important because they help to prevent accidents relating to the incorrect position of the landing gear, as well as protect the aircraft from

  How Do Landing Gear Indicators Work? Gear indicators use proximity sensors positioned on the landing gear and wheel to detect the position of the landing gear. These sensors are coupled with a processing module. Together, they provide the landing gear control system with position data for the landing gear. The landing gear control software

1. Weight Landing gear typically makes up between three and six percent of the total weight of an aircraft. Even though fixed gear is typically lighter than retractable gear, it increases aerodynamic drag when the aircraft is in flight. To address the challenge of landing gear weight, designers use materials that are lightweight but strong.

A wheel braking system in the landing gear helps to slow down the aircraft, while a steering system facilitates movement of the aircraft while it is on the ground. Types of Aircraft Landing Gear Many aircraft use retractable landing gear, which reduces drag while the aircraft is in flight. This type of landing gear uses
