IMPACT & INTACT

Scope

Focus: Noise, CO₂, Non‑CO₂ Phases: Taxi‑out, Departure/Climb, Cruise, Descent/Arrival, Taxi‑in, Wheels‑up/‑down, Gate‑to‑Gate Metrics: Noise, Non‑CO₂, Fuel burn/CO₂

Overview

The Integrated Aircraft Noise and Emission Modelling Platform (IMPACT) is a web application for assessing the impact of aviation on the environment in terms of noise, gaseous and particulate emissions. It implements the BADA 4-based Total Energy Model for modelling flight trajectories.

IMPACT is compliant with the ECAC Doc 29, and an approved model for conducting assessment within the MDG of the ICAO CAEP.

IMPACT is a solution for airspace changes in a TMA for SID, STAR and vertical procedures, as well as for network route changes studies and analysis of en-route flight procedures including flight efficiency.

Another option to use IMPACT is for airport noise exposure assessment according to best practice, which supports the END 2002/49/EC and the ICAO Balanced Approach. It also provides the required flexibility to address more specific requirements linked to national regulatory airport noise mapping.

The outputs are as follows:

Fuel consumption and emissions – fuel burn/CO₂ masses, 25 pollutant masses (NOx, SOx, HC, CO, PM, etc.), aggregation of results per phase of flight, time, FL range etc.
Airport noise – noise contours for metrics such as: SEL, Lden, DNL, LAeq, LAmax, NAx; noise contour area and number of people inside the contours.

IMPACT supports ANSPs in their environmental efforts as follows:

Advanced Assessments: IMPACT provides detailed assessments of fuel consumption, emissions and noise impacts of air traffic operations. This helps ANSPs understand the environmental footprint of their activities.
Regulatory Compliance: The tool aligns with international standards and regulations, such as those set by ICAO, ensuring that ANSPs meet necessary environmental requirements.
Scenario Analysis: IMPACT allows ANSPs to model different operational scenarios and their potential environmental impacts. This helps in planning and implementing more sustainable Air Traffic Management practices.
Data-Driven Decisions: By providing accurate and comprehensive data, IMPACT enables ANSPs to make informed decisions about how to reduce their carbon footprint and improve sustainability.
Transparency and Reporting: The tool supports environmental transparency by helping ANSPs report their environmental performance and progress towards sustainability goals.

Versions and OS Requirements

Web-based application which does not have specific versions (other than internal updates) and OS requirements.

INTACT is an automated version of IMPACT for assessing local impact of air traffic on the environment.

It provides real-time assessment and allows processing of large volume of data. It is connected directly to data sources like airport data and ATM data, can configure static data and control and monitor live exercises. This includes the creation of live noise maps and live emissions graphics.

Data Requirements

Supported input data types include the following: airport, RWY, ground tracks (point or vector tracks), vertical flight procedures, pre-calculated “4D” trajectories (engine thrust values are required in this case) and detailed list of operations.

Limitations

Areas which are not covered by IMPACT:

En-route noise – only modelling below 10.000ft possible.
Rotorcraft noise and emissions modelling.
Ground APU and taxiing noise and emissions.
Overflight noise & emissions.
Airport local air quality.
