Skid landing gear is a type of landing gear commonly used on helicopters and some light aircraft. Unlike traditional wheels, skids are typically made of metal or composite materials and are designed to slide along the ground during landing and takeoff. This design helps reduce weight and complexity, making it ideal for operations in rough or uneven terrain. Skid landing gear provides several advantages, including lower maintenance costs and improved stability on soft surfaces. It allows aircraft to land in areas where conventional landing gear might struggle, such as mountainous regions or remote locations. This versatility makes skid landing gear a popular choice for various aviation applications.
