The ZSh-7V crash helmet is designed to protect pilot’s head from injuries both in the cockpit during flight or emergency escape from the helicopter. The crash helmet protects pilot from blinding sunlight and cockpit noises, provides two-way radio communications, and can be fitted with various helmet-mounted observation devices (OVN-1 or GEO-ONV-1 night vision goggles) and oxygen mask. The helmet can be used in any aircraft with an airspeed under 400 km/h. Maximum altitude for using the helmet with the oxygen mask is 6,000 metres.
