ABSTRACT
BEL and AAI collaborate on Air Traffic Management Systems In a major boost to its own diversification drive into non-defence and the Government's 'Make in India' programme, Bharat Electronics Limited (BEL) and Airports Authority of India (AAI), under it's R&D initiative, at Wings India 2022, entered into an agreement for the joint, indigenous development of systems for air traffic management and surface movement of aircraft at airports in the country which were hitherto being imported. Under this Agreement, BEL and AAI will jointly develop Civil Air Traffic Management System (ATMS) with Advanced-Surface Movement Guidance and Control System (ASMGCS), a complex ground surveillance system that manages air traffic at airports and in Indian Civil Airspace for safe operation of flights from take-off to landing. The aim of ATMS with ASMGCS is to provide the air traffic controller with the complete air traffic picture of the coverage area while interacting with Primary/ Secondary Radar, Automatic Dependent Surveillance-Broadcast (ADS-B), Multi-lateration System (MLATs), and navigational equipment such as GPS, Instrument Landing System (ILS) and Doppler Very High Frequency Omni Range (DVOR). Boeing: India to lead South Asia air traffic growth Boeing shared projections for South Asia's commercial aviation sector over the next 20 years, with the region leading the world in yearly passenger traffic growth.
ABSTRACT
COVID-19 pandemic starting in early 2020 has greatly impacted human and industrial activities. Air transport in China shrank abruptly in February 2020, following a year-long gradual recovery. The airline companies reacted to this unprecedented event by dramatically reducing the flight volume and rearranging the aircraft types. As the first major economy that successfully controls the spread of COVID-19, China can provide a unique opportunity to quantify the medium-long impacts on the air transport industry. To quantify the corresponding changes and to elucidate the effects of COVID-19 in the wake of two major outbreaks centered in Wuhan and Beijing, we analyze twelve flight routes formed by four selected airports, using the Automatic Dependent Surveillance-Broadcast (ADS-B) data in 2019 and 2020. Our results show that the total flight volume in 2020 reduced to 67.8% of 2019 in China. The recovering time of flight volume was about 2-6 months, dependent on the severity. In order to unwind the severe challenge, airlines mainly relied on aircraft B738 and A321 between February and June in 2020 because the fuel consumption per seat of these two aircraft types is the lowest. Besides, fuel consumption and aircraft emissions are calculated according to the Base of Aircraft Data (BADA) and the International Civil Aviation Organization's Engine Emissions Databank (ICAO's EEDB). At the end of 2020, the ratios of daily fuel consumption and aircraft emissions of 2020 to 2019 rebounded to about 0.875, suggesting the domestic commercial flights were nearly fully recovered. Our results may provide practical guidance and meaningful expectation for commercial aircraft management for other countries.
