A comprehensive analysis of environmental factors shaping the impact of aviation activity on the environment has been carried out, including emissions of harmful substances, acoustic pollution, and thermal and vibrational effects. The operational characteristics of aircraft determining the scale of CO2, NOx, SOx, CO, and particulate matter emissions at different flight phases have been systematically examined. The dependence of emission intensity on engine type, combustion parameters, and flight altitude – which influence photochemical processes in the tropopause – has been evaluated. A comparative analysis of the environmental characteristics of turbojet, turbofan, hybrid, and electric aircraft engines revealed a trend toward reduced specific fuel consumption and pollutant levels due to increased thermodynamic cycle efficiency. The nature of acoustic loads generated by engines, landing gear, and aerodynamic body elements has been studied, identifying zones of the greatest impact near airports. International standards on aircraft noise exposure and noise reduction methods have been analyzed, establishing correlations between propulsion system design parameters and noise emission levels. This enables optimization of turbine blade and nozzle architecture to minimize sound pressure levels. Secondary factors of environmental impact have been separately considered, including pollution caused by fuel and lubricants, de-icing agents, maintenance byproducts, and the formation of contrails and induced cirrus clouds that alter the atmospheric radiation balance. Monitoring data confirming spatial nonuniformity of pollution around airports and along flight corridors have been analyzed. Technological directions for minimizing harmful emissions have been summarized, particularly the implementation of low-temperature combustion technologies, and the advantages of hybrid-electric propulsion systems have been identified, achieving CO2 emission reductions of 30–50%. The effectiveness of digital modeling of combustion chamber processes for predicting environmental performance at the design stage has been demonstrated. A conceptual model of ecological monitoring for aircraft operation has been developed, integrating Big Data analytics, Internet of Things (IoT), and digital twin technologies for real-time control of emissions, noise, and fuel consumption. The integration of monitoring results into airport environmental management systems has been proposed, following a concept that includes energy-efficient infrastructure, renewable energy utilization, and waste recycling. The necessity of applying economic incentives for aviation enterprises – such as environmental certificates, tax benefits, and support for innovative projects – has been substantiated. Special attention is paid to personnel training, environmental awareness, and institutional cooperation between aviation and environmental protection authorities.
