Japan's NEC Corporation can help airports improve air safety where the problem can strike anytime, undetected.
NEC recently introduced a Bird Protection Detection Solution that can help airports better monitor the flight of birds in the area and possibility avert any problem that can pose risks to aircrafts and their passengers.
Incidents of birds colliding with aircraft - called bird strikes -- have been reported worldwide. Such incidents have become serious problems for some airports, which are responsible for ensuring a high level of safety.
To help airports, NEC developed the solution that can detect the positions of birds and collect data on the classification of these birds.
Ordinarily, watching birds in the airport area is the responsibility of airport "bird patrol" staff. However, this solution is more prone to human error, including human fatigue and lack of manpower.
Using a variety of technologies, such as radar, video equipment, data processing devices, and sound apparatus, NEC is helping airports such as the Tokyo International Airport (Haneda) to ensure a high level of airport safety.
The radar measures the movement of birds in flight, including the altitude and distance of birds from the airport.
Video cameras support these radars by observing objects on the ground surface. NEC said these objects may be difficult for radars to detect automatically. There are also rotating cameras for automatic bird detection, but these cameras can also be manually focused to monitor and record specific bird species.
Using sound apparatus, the NEC solution can detect specific sounds of birds to help monitor their movement.
Finally, the data processing devices, such as terminals, are used to display visual and statistical information for better analysis, planning and management. Such devices can display in real time the trajectory of birds, their history, movement and territory.
Bird data can also be further studied to understand the birds' behavioural patterns.
NEC said such airport safety solution helps airports secure the area for the safety of aircrafts and passengers.
"The introduction of NEC's new solution helps to ensure the early detection of birds by continuously monitoring airports and their surroundings, which enables greater efficiency in the implementation of control measures," said Masahiro Takahashi, general manager, Air Transportation Solutions Division, NEC. "This solution is particularly valuable for reducing the occurrence of bird strikes at airports that operate 24 hours a day and are faced with the difficulty of visually confirming bird sightings during long night-time hours."
