| What is the purpose of noise contours in the context of the Amritsar Airport study? | to study the current noise impact of planes flying away and toward to a specific airport | 1. Introduction Contract No: GEMC-511687779954930 Custom Bid for Services Noise mapping and declaration of Airport Noise zones at Amritsar Airport The following report describes the study carried out for the civil airport of Amritsar, based in north India, to understand the noise impact generated by its flight activity. This study complaints the Indian regulations about airport noise, as described in the following pages. The study shows the results of a noise model made from 2023 flights data. The noise model has been processed by a specific software worldwide used that let users to calculate noise contours. Noise contours are helpful to study the current noise impact of planes flying away and toward to a specific airport. | 643 | definition | 1.000 | Noise contours are helpful to study the current noise impact of planes flying away and toward to a specific airport. | 5 | page=5,block=5 | 0.700 | valid |
| What is the stage parameter in departure profiles associated with? | a noise related parameter which is connected with MTOW | About departure profiles, these are divided by stage values. Stage is a noise related parameter which is connected with MTOW. Since is easier to manage distances than MTOW then stage depends on the trip distance as shown in the following image. Image 13: Stage meaning. About landing usually there is only one profile featured by stage 1. That’s why usually during the approach planes are in idle position or the thrust is limited and used just to contrast wind effects. 4.3. Weather AEDT databases store local weather information. For the current study an average based on the period 2012-2021 have been used. Data comes from ISD (Integrated Surface Database).

| What does LAeq,T signify in terms of noise levels? | the constant noise level that would result in the same total sound energy being produced over a given period | It is the daily long term average calculated on the day and night period, setting up the time period from 06:00 to 22:00. Equation 3: DNL. LAeq,T is the the constant noise level that would result in the same total sound energy being produced over a given period. Indian regulation gives two periods: day (from 06:00-22:00) and night (from 22:00-06:00). Equation 4: LAeq. LAmax is the maximum sound level recordered over a given period, in this case during the whole average day. | 153 | definition | 1.000 | LAeq,T is the the constant noise level that would result in the same total sound energy being produced over a given period. | 24 | page=24,block=5 | 0.700 | valid |
| What is the purpose of the INM algorithm? | to evaluate long term average noise | INM is not designed to calculate noise made by a single aeronautic movement and its algorithm is made to evaluate long term average noise. In this way it is not necessary to input flights for each 365 days of the year. INM works with the “yearly average day” which is made by the average use of the airport (average aircraft types, tracks, procedures, weather). The software is able to model noise coming only from departures and approaches within specific altitude limits of the aircrafts (noise calculation made by approaches starts from 6,000 ft while noise calculation made by departures cut is not performed over 10,000 ft). Noise made by APU and from taxing is not calculated but usually this is a neglectable energetic contribution comparing to sound energy of departures and landings. A built-in option let the user to model noise from run ups. | 102 | definition | 1.000 | INM is not designed to calculate noise made by a single aeronautic movement and its algorithm is made to evaluate long term average noise. | 10 | page=10,block=5 | 0.700 | valid |

| What are Afterwards noise measurements? | performed to evaluate the real noise impact of Amritsar flights activity and to better investigate where to instal permanent noise measurement system | A noise model, starting from 2023 flight data,was processed by a specific software worldwide used, called AEDT, that let users to calculate noise contours. Afterwards noise measurements were performed to evaluate the real noise impact of Amritsar flights activity and to better investigate where to instal permanent noise measurement system. Noise data were analyzed by SARA software which was able to correlate noise events to aircraft movements and then to calculate Lden and other noise indicators. | 191 | definition | 0.980 | Afterwards noise measurements were performed to evaluate the real noise impact of Amritsar flights activity and to better investigate where to instal permanent noise measurement system. | 40 | page=40,block=4 | 0.850 | valid |
| What data do NPD curves provide? | noise data for a specific plane in a specific condition | Image 4: NPD set example2. To calculate noise at receiver points INM uses the segmentation process. This method takes into account the NPD (Noise – Power – Distance) data. NPD curves provide noise data for a specific plane in a specific condition and the noise can be modify using correction factors such as air pressure or flight angles. The software analyses horizontal track projections (on the ground) and using flight procedures and motion equations it starts to draw a 3D flying path. The 3D flying path is then divided in several segments and for each segment INM calculates noise made by a specific plane taking into account correction coefficients.

| Why is high accuracy in track modeling not necessary for Amritsar airport? | the high acoustic energy comes during the straight segment for both departures and landings | 4.3. Flying tracks Tracks have been drawn following Customer information and real ADSB flight tracks. It is good to underline that since the aircraft traffic featuring Amritsar airport is not high there is no need to model with high accuracy a track because the high acoustic energy comes during the straight segment for both departures and landings. To simulate deviation from SID, tracks dispersion has been settled up on departures tracks. Departures 34- 16 Departures 16- 34 | 258 | relationship | 0.970 | It is good to underline that since the aircraft traffic featuring Amritsar airport is not high there is no need to model with high accuracy a track because the high acoustic energy comes during the straight segment for both departures and landings. | 18 | page=18,block=4 | 0.700 | valid |
| What is the typical thrust setting during the approach phase of an aircraft landing? | idle position or the thrust is limited and used just to contrast wind effects | About departure profiles, these are divided by stage values. Stage is a noise related parameter which is connected with MTOW. Since is easier to manage distances than MTOW then stage depends on the trip distance as shown in the following image.
