New training polygon was opened in the area of Kralovehradecky airport on November 10th, 2016. The new polygon will be used for raising the safety on roads. DSA a.s. took place at the event with its helicopter OK-DSN. It is twin-engine helicopter with which we regularly take place at Moto GP in Brno where we provide the urgency helicopter service for the racers. We are glad we could introduce this helicopter AS355 at this event.
