helicopter at
Heathrow Airport, now operated by the
National Police Air Service aircraft, which make up the majority of their fleet. The larger EC145 aircraft are primarily reserved for use in London. All police air support in England and Wales is provided by the
National Police Air Service (NPAS). NPAS uses
Eurocopter EC135 and
EC145 helicopters, alongside
Vulcanair P68R planes. Twin engined aircraft are required, as air support units (ASU) are often required to fly over urban areas. Aircraft are fitted with an array of surveillance, navigation and communication technology to help them with a wide variety of tasks. The specific tasks that any one police helicopter performs will vary from force to force, but common deployments are for
missing person searches, vehicle pursuits, the tracking of suspects, and maintaining public order. Scotland and Northern Ireland have separate air support units.
Police Scotland utilises a single EC135, whilst the
Police Service of Northern Ireland operates two EC135 and one EC145 helicopters. Police aircraft can be used for
MEDEVACs, however, these are rarely performed due to the availability of
HM Coastguard helicopters and charitably funded
air ambulances – both of which offer enhanced medical care with the availability of a paramedic and/or doctor on board.
Crew A single pilot civilian operates each aircraft. Most pilots operating police aircraft come from a military background – and as such have the required flying hours and experience to safely fly at low-levels and for prolonged periods of time. The standard crew in a police helicopter consists of two tactical flight officers (TFO). A front seat observer is responsible for operating the helicopter's surveillance systems. The rear seat observer, responsible for communications using the TETRA radio and downlink systems. NPAS' P68 fixed-wing aircraft only operate with one TFO due to weight restrictions. TFOs are sworn police officers who have extensive experience on the ground, and also carry all the equipment a normal police officer would onboard – should the aircraft be required to land to assist or make an arrest. All pilots are civilians, and have no police powers. ==Watercraft==
