76 extractive question-and-answer pairs built from Dehradun Airport, published by aai.aero. Every answer is a verbatim span of text the source prints, and each row carries the passage it sits in, its offset in that passage, the source quote, the page and the location in the document, so any row can be checked against the original. 31 of the 76 pairs (40.8%) are explanatory questions and 45 restate a figure. 100.00% of rows pass the corpus quality gate.

| What is the function of the Aviation Environmental Design Tool (AEDT)? | to estimate 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 Dehradun 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 Dehradun 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. | 365 | 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. | ||||
