Rotary-wing Aircraft
The most common form of police rotary-wing aircraft is the helicopter, but other types of rotary-wing aircraft such as autogyros are also used. The Groen Hawk 4 autogyro was used during the 2002 Winter Olympics in Salt Lake City, Utah.
Police rotary-wing aircraft are normally equipped with special equipment, including night vision, FLIR, surveillance cameras, radar, special radio systems and engines, loudspeaker systems, tear gas dispensers, searchlights, winches and winch cables, flashing light beacons, police rescue equipment and special seating. Weapons are not usually attached to the aircraft. Police rotary-wing aircraft are sometimes equipped to perform multiple functions, or are designed so that equipment can be changed quickly when required for divergent roles. For example, a rotary-wing aircraft could be used for search-and-rescue, and then as an air ambulance.
Police forces sometimes use military surplus rotary-wing aircraft, such as the Bell UH-1 Huey. Some policing organisations, such as the Policía Federal in Mexico, acquire new military rotary-wing aircraft such as the Sikorsky UH-60 Black Hawk. However, most buy civilian rotary-wing aircraft directly from major aircraft companies or lease them from specialty suppliers.
