Rotary Aircraft
Benefits of using helicopters are very obvious. Transport helicopters are used in places where the use of conventional aircraft is impossible. The landing possibilities of helicopter are almost unlimited. Transport helicopters are helicopters used by militaries with the primary purpose of transporting personnel (troops) and cargo. The benefit of using helicopters is that personnel and cargo can be moved to and from locations without requiring a runway for takeoffs and landings. Cargo is carried either internally, or externally by sling load where the load is suspended from an attachment point underneath the aircraft. Personnel are primarily loaded and unloaded while the helicopter is on the ground. However, when the terrain restricts even helicopters from landing, personnel may also be picked up and dropped off using specialized devices, such as rescue hoists or special rope lines, while the aircraft hovers overhead.
