ATC Tower Console Testing and Installation across Multiple Airports

Successfully replaced existing operational ATC consoles with modern EVANS console systems across 10 airports including Biratnagar Airport, Nepalgunj Airport, Rumjatar Airport, Rajbiraj Airport, Dang Airport, Sanfebagar Airport, Doti Airport, Phaplu Airport, Thamkharka Airport and Balewa Airport. The project involved installing two-man position ATC console furniture at major airports like Biratnagar and Nepalgunj, and one-man position AFIS consoles at smaller hilly and mountainous airports such as Rumjatar, Phaplu, Thamkharka, and the remote locations of Doti and Balewa. Integration included Rohde & Schwarz VHF equipment, Vaisala meteorological systems, and Total Recall digital voice recorders across all 10 locations. Major challenges included working with diverse weather patterns and hostile topography across remote Nepal locations, with some airports like Doti, Phaplu, and Thamkharka requiring over 3 days travel to reach. Due to limited grid electrical power supply in hilly and mountainous areas, particularly at Rumjatar, Doti, Sanfebagar, Phaplu, Thamkharka and Balewa airports, solar power-based systems with heavy capacity 400Ah@C10 batteries were installed with redundancy switches for reliable operation. The VHF Multimode Digital Radio systems (3 sets per airport) provide excellent RF performance with advanced digital signalling technique for future radio communication needs across all locations. Each of the 10 airports is now equipped with fully-featured professional voice logging systems for aviation safety, and the installation created safer, more comfortable workplaces enabling aviators to operate safely in challenging terrain with advanced computer-based remote control and monitoring systems for wide-area ATC applications.
