Police aviation in United Kingdom provides British police forces with an aerial support unit to assist them in pursuit, surveillance and tracking. All police aviation in England and Wales comes under the National Police Air Service (NPAS), while Police Scotland and the Police Service of Northern Ireland operate independent units.
In addition to its fleet of helicopters, NPAS has introduced four Vulcanair P68R, which are fixed-wing aircraft able to provide longer flying time and lower running costs.
Police aviation in England and Wales was once a force-by-force, or forces working in partnership, organisation, however from 2012 to 2015 it transitioned to NPAS. [1]

The large mural, depicting the 1936 Battle of Cable Street public order incident on the side of St. George's Town Hall in the East End of London, depicts the police autogyro overhead that was present on the day. [3] [4] [5]
Aerial units are often tasked to assist in vehicle pursuits. Air support allows ground units to disengage and follow from a discreet distance, hopefully making the pursuit less dangerous while still allowing ground units to be able to close in quickly as directed to apprehend suspects. Aerial surveillance also allows the police to anticipate the direction of the pursuit, and position ground units ahead of the suspect to block roads or deploy spike strips. Aerial units can also be used to efficiently locate missing persons.
Police helicopters are crewed by three people; a civilian pilot and two tactical flight officers (TFO). The pilot and a TFO sit up-front with eye contact with the ground. The TFOs are responsible for controlling the camera systems, recording images for evidence in court and navigation, including aiding the pilot.
During an incident, ground and aerial units are able to communicate directly with each other, using the call sign of the unit.
Most police helicopters are fitted with a sphere shaped housing or pod usually under the nose of the aircraft the purpose of which is to support and stabilise two cameras using a gyroscope stabilisation system. The two cameras are a standard "day camera" (a colour camera equipped with a powerful zoom lens) and a thermal imaging camera, which enables heat to be detected and is usually utilised during hours of darkness or in the search for persons in hiding. The cameras are normally connected to controls located in the cabin of the aircraft that allow the air observer to directly control them. They are also linked to a recording system and downlink system. The Vulcanair P68R aeroplanes are fitted with a Wescam MX-15. [6]
Force helicopters are usually equipped with a powerful "Nightsun" search light that is capable of illuminating a large area. [7]
The Metropolitan Police Service has reportedly been secretly using Cessna aircraft for a number of years that have been fitted with surveillance equipment capable of intercepting mobile phone calls and listening in on conversations. [8]

In 2010, The Guardian reported police forces and government agencies across the UK are exploring the potential of unmanned drones for covert aerial surveillance, security, or emergency operations. They said at least four forces – Merseyside, Essex, Staffordshire and British Transport police – have bought or used microdrones. Microdrones can be fitted with video cameras, thermal imaging devices, radiation detectors, mobile-phone jammers and air sampling devices. Hovering at heights of around 60 metres (200 ft), they are said by manufacturers to be virtually invisible from the ground. The costs of operating the drones are considerably less than operating helicopters. [9]
A member of the crew, usually a police constable, occupies the rear seat of the helicopter. The primary purpose of this crew member is to relay critical information to police units that are on the ground. In the case of traffic pursuits, this crew member will provide a running commentary of the exact location of the suspect's car, utilising either paper maps or a computerised mapping and navigation system.
Police helicopters are usually fitted with radios capable of transmitting and receiving communications on their force's and other force's Airwave TETRA radio system. More recently, police helicopters have been fitted with a device that allows live video images to be transmitted directly to the force command centre by way of a downlink system. [7] Commonly fitted to the underside of the helicopter is a public address system, known as "Skyshout". [7]
In situations where a patient is critically injured, the police helicopter can be called upon to provide air transport of a patient, directly to the most appropriate major trauma centre. CASEVACS, or casualty evacuation, are uncommon, but can be carried out if no HM Coastguard or air ambulances are available. Police helicopters carry basic life support equipment, along with a stretcher for transport. A doctor or paramedic can travel with the patient, monitoring them from the spare seat.
The following is a list of police aviation units in the UK and the forces or areas to which they are assigned.

The Airbus Helicopters H135 is a twin-engine civil light utility helicopter produced by Airbus Helicopters, formerly Eurocopter. It is capable of flight under instrument flight rules (IFR) and is outfitted with a digital automatic flight control system (AFCS). First flying in February 1994, it entered service in 1996. 1,400 have been delivered up to September 2020, to 300 operators in 60 countries, accumulating over 5 million flight hours. It is mainly used for air medical transport (medevac), corporate transport, law enforcement, offshore wind support, and military flight training. Half of them are in Europe and a quarter in North America. The H135M, certified under the name Eurocopter EC635, is a military variant, so the overall design is known as the Airbus Helicopters H135 and the military version, as the Airbus Helicopters H135M. The EC135/H135 is a development of the earlier Messerschmitt-Bölkow-Blohm (MBB) Bo 105.
The Air Support Unit (ASU) was a Central Operations branch of London's Metropolitan Police Service. The main responsibility of the unit was to provide aerial reconnaissance and other air support operations. Helicopters are particularly useful in aiding searches for missing persons, car pursuits, suspect capture and large public order operations such as football matches. The ASU also supported other emergency services, including the London Fire Brigade, London Ambulance Service and Marine Coastguard. On 31 March 2015, the National Police Air Service took over providing air support to the Metropolitan Police Service. This resulted in the closure of the Metropolitan Police Air Support Unit.
