Product Manual

Helicopters occupy their own special niche within the aviation community. The 302H was the first ELT developed in recognition of the fact that a helicopter crash is dynamically different from a fixed wing crash. To our already field proven EBC 302 with its history of reliability and successful operation, we added a second 360˚ azimuthal accelerometer to create a true 360˚ spherical 6-axis G-switch. The EBC 302H will respond to a crash force from any direction – Up, Down, Left, Right, Front, Back. Only Emergency Beacon Corporation, dedicated solely to search and rescue products, has designed such a practical unit.

The EBC 302H has been engineered for helicopter operation by reducing the sensitivity to low-frequency turbine vibration and rotor input, thus making this ELT more immune to false activation while retaining a high sensitivity in actual crash situations.

If helicopters are your concern, insist on the ELT designed for your special needs – the EBC 302H, the Helicopter Emergency Locator Transmitter.

The EBC 302H is FCC Type Accepted under Part 87.
