The NH90 aircraft is a military transport helicopter. The simulators may be made available to customers in the military context only. The NH90 aircraft is distributed in the European and extra European regions. The need for training on synthetic training media results from the demand of education and training of the NH90 pilots themselves and from the missions on the real helicopters. The pilots shall train for economicyl and safety reasons on the real helicopters and on synthetic training media. Furthermore, the synthetic training media may be used by test pilots, instructors and technical personnel for a broad spectrum of optional training goals. The training media are principally made available to pilots from the German forces (army and air force) and to international NH90 aircrew.
