Wireless Comms Convenience
Until recently, the great irony of aircraft wireless communications was that the actual headsets or helmets used by helicopter pilots or other crew members were connected to their radios/intercoms by wired drop cords. Although convenient, these drop cords tethered helicopter crews to their aircraft, limiting their mobility and freedom of movement within and nearby the aircraft cabin.
Today, pilots and copilots remain plugged into their helicopter’s wired comms system for safety reasons. But Axnes’ PNG WICS has solved this problem for everyone else by allowing aft crew members such as EMS personnel, hoist operators and SAR technicians to connect wirelessly through onboard base stations, control panels, and handheld wireless transceivers that connect to their headsets and helmets.
“We eliminate the wires between the aircraft and headsets/helmets so that crew members can move around freely within the cabin,” says Markus Schmitz, managing director of Axnes’ U.S. operation. “Because our PNG system uses the UHF band, our handheld

transceivers allow users to not only move within the cabin and around the aircraft, but also to achieve significant communication distances during airborne operations, typically up to 3-5 miles away, depending on the terrain and elevation.”
Adding wireless connectivity – in this case by using Bluetooth – is just one feature of Anodyne Electronics Manufacturing (AEM) Corporation’s P139-HD Digital Audio System, “which is the industry’s most capable digital audio system for special-role aircraft,” says Tony Weller, AEM’s director of sales and marketing. The P139-HD can go wireless by adding the Bluetooth Audio Accessory (BAA01) to the helicopter’s control panel. “Enabling the Remote Transmit selection feature of the P139-HD or adding the RTS01 to existing audio systems allows the user to conveniently toggle the TX Select to the desired communication radio without letting go of flight controls,” he says.
AEM’s airborne comms equipment is being used by the Texas Department of Public Safety, U.S. Customs and Border Protection, Tokyo Metro Police, and Los Angeles County Sheriff’s Department, among others.
