The extension cable (EC-6) is an optional cable that attaches to Voyager's nose and plugs into an aircraft like a traditional GPU. This option is useful if an aircraft has an obstructed NATO plug or if a pilot wants to use the Voyager without removing it from a storage compartment. The extension cable also helps some fixed-wing pilots avoid exposure to prop wash during Voyager starts.The extension cable uses the highest quality components to ensure maximum power transfer and unchanged voltage profiles during cabled starts. It's also light weight and easy to coil. The standard length of the extension cable is six feet, but custom lengths are possible.
