SW-4

Multirole capability to satisfy present and future operational requirements, has been one of the priority  targets of the PZL Swidnik engineers in designing the helicopter architecture.
SW-4 Puszczyk is perfectly suited for passenger transport, primary  and advanced training, patrolling and surveillance. Helicopter provides the best range of operation in its class. The use of the SW-4 for training purposes by the Polish Army ensures it meets pilot training regulations and NATO standards.
Puszczyk has hydraulic powered removable dual controls, crashworthy seats and capability for day and night flights simulating IFR. Furthermore, it is  compatible with NVG goggles. Emergency simulation unit allow to simulate helicopter stability and controllability in emergency situations such as: hydraulic system failuare, attitude indicator failuare, gyro-compas failuare.
