The airplane volume (3,4m х 3,2m х 14.1 м), as well as the payload of experimental equipment, allocated in the laboratory compartment, advantageously single out our airplane from the similar ones in the world. The results of tests and experiments are registered by the standard on-board aircraft systems and additional test- and measuring equipment of the customer. The video- and photo-shooting are also available on board, as well as the subsequent processing of all the taken video- and photo- materials (if deemed necessary).
