Police aviation is the use of
rotary-wing aircraft,
fixed-wing aircraft,
nonrigid-wing aircraft or
lighter-than-air aircraft in
police operations. Police services commonly use aircraft for traffic control, ground support,
search and rescue, high-speed car pursuits, observation, air patrol and control of large-scale public events and/or public order incidents. In some major cities, police rotary-wing aircraft are also used as air transportation for personnel belonging to
SWAT-style units. In large, sparsely populated areas, fixed-wing aircraft are sometimes used to transport personnel and equipment.
