Ground Support De-icing System

David Clark Ground Support Military Headsets

The Series 3800 Aircraft De-icing System is a COTS solution designed to provide communication solutions while enhancing efficiency and safety during aircraft de-icing, anti-icing and maintenance operations.

The Series 3800 system has a track record of proven performance in hundreds of military airfields and civilian airports throughout the world. The system improves communication between de-icer cab and bucket, resulting in more productive application of costly de-icing fluids and helps prevent accidental damage to aircraft during de-icing operations.

The Series 3800 system consists of noise-attenuating headsets and rugged, weather-tight intercom-only modules and power cords that provide hands-free, full-duplex intercom communication (see typical system configuration).
