| What is the purpose of the Aviation Environmental Design Tool (AEDT)? | the environmental consequences of aviation actions, such as airport noise, fuel consumption, and air pollutant emissions | The Noise mapping and Noise zone study was carried out at Coimbatore International Airport as per requirement of the Environment (Protection) Amendment Rules, 2018. Noise maps and noise zone were developed by using the Aviation Environmental Design Tool (AEDT). AEDT is the standard software developed by The Federal Aviation Administration (FAA) US, AEDT is a integrated software to estimate the environmental consequences of aviation actions, such as airport noise, fuel consumption, and air pollutant emissions. The basic input data for noise modelling is flight operation data. The flight operations of one year (from 1st Jan 2023 to 31st Dec. 2023) were obtained from Coimbatore airport. The flight data covers the details of each flight that was operated at airport including: runway usage, flight registration no, Airline operator, Call sign information, date, time, route etc. | 393 | definition | 1.000 | AEDT is the standard software developed by The Federal Aviation Administration (FAA) US, AEDT is a integrated software to estimate the environmental consequences of aviation actions, such as airport noise, fuel consumption, and air pollutant emissions. | 12 | page=12,block=11 | 0.700 | valid |

| What is the purpose of sending a letter to airlines exceeding the Lmax limit? | to raise awareness among the operators to fly quietly. | Doc. No.: 106- Noise Mapping and Noise Zone Study at Coimbatore Airport Page 29 of 36 With these limits only few operations would have been in excess, whereas they will safeguard the currently existing noise climate at both locations. It is suggested to send a letter to those airlines operators that exceed the limit, indicating the measured Lmax level. The main purpose of this would be to raise awareness among the operators to fly quietly. At a later stage the limits may be reconsidered downwards, in order to enforce even quieter flights, and it shall be a part of the Noise Action Plan. | 389 | relationship | 0.970 | The main purpose of this would be to raise awareness among the operators to fly quietly.

These Lmax value shall be reviewed as and when there is a requirement in future. (2) For Proposed Airports (yet to be operationalized): (i) For any upcoming/New Airports, noise modeling shall be conducted by the airport operators and results should be submitted to the Ministry of Environment, Forest and Climate Change while seeking Environment Clearance under the Environment Impact Assessment Notification, 2006. (ii) The airport operators should also develop airport noise zone as specified in paragraph 4 and share the same with Ministry of Housing and Urban Affairs and concerned State Development Authority for necessary land use planning around airport. | 416 | relationship | 0.970 | (2) For Proposed Airports (yet to be operationalized): (i) For any upcoming/New Airports, noise modeling shall be conducted by the airport operators and results should be submitted to the Ministry of Environment, Forest and Climate Change while seeking Environment Clearance under the Environment Impact Assessment Notification, 2006. |
