EADS obstacle warning system for Royal Thai Air Force
* HELLAS warns helicopter pilots about obstacles
* Considerable increase in flight safety
Friedrichshafen, 25 August 2005
EADS has equipped two helicopters, deployed by the Royal Thai Air Force for transporting VIPs, with the HELLAS obstacle warning system. As EADS Defence Electronics announced on Thursday, representatives of the Thai State Ministry and the Royal Thai Air Force have signed the acceptance documents at Lop Buri air force base, approximately 150 kilometres north of Bangkok.
Prior to the HELLAS-W (Helicopter Laser Radar Warning) being officially handed over to the Royal Thai Air Force, the HELLAS systems were integrated on site into the two Bell 412 EP helicopters. At the same time, pilots and mechanics were trained and test flights carried out. For the first time, an additional LCD screen was installed in the cockpit of the helicopters and a video camera fitted to the sensor. This means the pilots and passengers can also see the obstacles parallel to the warning displays.
Obstacles that are difficult to make out are always a major threat to helicopters,” explained Bernhard Gerwert, Head of the EADS Defence Electronics Business Unit. “You can however come to grips with this threat by deploying technology that is already available today and greatly enhance the safety of the pilot and passengers as a result.”
The HELLAS helicopter laser radar is the only operational warning equipment in the world that can protect helicopters reliably against obstacles such as high-voltage transmission lines. It scans its surroundings with a laser beam, which is not harmful to the human eye and detects even thin wire at a great distance and with high precision. Wires which cannot be seen by the pilot are detected reliably and timely. The pilot is given information on obstacles in the flight path, such as high-voltage transmission lines, wind power generators or trees, via optical and acoustic signals, which enable evasive action to be taken at an early stage. This means HELLAS reduces the risks encountered during helicopter operations, even under difficult conditions such as low altitude, poor visibility or a landing in unknown terrain and in this way enhances flight safety considerably. The equipment is already used in the helicopters of the German Border Guard.
