New nav and comms for DRF Luftrettung birds
DRF Luftrettung has unveiled a new navigation and radio communications system to be installed on its rescue helicopters.
DRF Luftrettung has unveiled a new navigation and radio communications system to be installed on its rescue helicopters. The new set-up offers three times as many radio channels as were available on the old system.
The air ambulance provider said that other benefits include a common cockpit layout and the option for visual flight planning. Flight plans can be entered and viewed directly on the device’s display screen. Another feature is the ability to perform satellite-based approaches, for example in difficult weather conditions. However, these approaches can only be made where a helipad and the approach procedures have been certified. The new kit is also smaller and lighter than the previous system.
The increase in channels is afforded by a channel spacing of 8.33 kHz, in line with EASA guidelines for aircraft radio and navigation systems that will come into effect in 2018, said DRF Luftretting. The previous channel spacing of 25 kHz allowed for 760 channels, whereas the new system offers 2,280.
Around 20 helicopters in the organisation’s fleet, including BK117s, EC135s and EC145s, will now be converted to carry the new equipment. Michael Kunze, DRF Luftrettung’s head of airworthiness, said that installing the new system will standardise the layout and operating procedures in all the helicopter types, which will enhance safety.
