Police pilots in Wiltshire have become the first to test a new mobile flight simulator to help sharpen their skills.
Police say the simulator will save on real flying time and costs
Its database of imagery ranges from the UK countryside to every airport across the world.
The system allows trainers to introduce sudden changes, such as fog, rain, turbulence and even other aircraft.
Mike Evans, head of Wiltshire's Air Operations Unit, said: "It will save police forces considerable real flying time and associated costs."
The simulator is operated by Police Aviation Services, based at Gloucestershire Airport.
A spokesman said it cut down on the fuel and wear and tear of using a real helicopter, and reduced the risks faced by pilots in training.
