Base of Aircraft Data (BADA)
Efficient air traffic operations rely on capability of Air Traffic Management (ATM) systems to realistically predict aircraft trajectories. Likewise, ATM research and development activities require modelling and simulations tools capable of replicating real life operations and aircraft performances as perfectly as possible.
To enable modelling and simulation of aircraft trajectories in support to various ATM research and operational applications, every aircraft in operation shall have a corresponding Aircraft Performance Model (APM).
This is why EUROCONTROL, in cooperation with aircraft manufacturers and operating airlines, has created and maintains an APM called BADA (Base of Aircraft Data).
Owing to this cooperation, BADA prevails as a unique product provided by EUROCONTROL to the aviation community worldwide.
BADA APM Families
BADA APM is based on a kinetic approach to aircraft performance modelling. It is made of two components – the Model specifications provide the theoretical fundaments used to calculate aircraft performance parameters and the Datasets containing the aircraft-specific coefficients necessary to perform calculations. There are two variants of BADA, referred to as Families:
|BADA Family 3||
Today’s standard for aircraft performance modelling providing close to 100% coverage of aircraft types in the ECAC area. Its objectives are to model aircraft behaviour over nominal part of flight envelope and to meet today's requirements for aircraft performance modelling and simulation.
The main features related to the maintenance and support of the BADA Family 3 are explained in the BADA Product Management document.Details on how the coefficients provided in the BADA Family 3 dataset for a specific aircraft type are defined are provided in the BADA Development document.
|BADA Family 4||This newly developed model family covers 70% of aircraft types in the ECAC area. It provides increased levels of precision in aircraft performances parameters over the entire flight envelope to enable modelling and simulation of advanced systems and future concepts.|

Users and Licensing
Access to BADA is given to Air Navigation Service Providers, research and development organisations, universities and commercial entities, to the extent necessary to enable them to work on Air Traffic Management related projects.
The use of BADA is regulated through a license agreement which stipulates the terms and conditions of use based on the contractual constraints EUROCONTROL is committed to with its data providers. The provision of access is subject to EUROCONTROL’s approval.
Request access to BADA
BADA can be used by anyone in the EUROCONTROL organisation and can be obtained by contacting the BADA Support Team.
An external party can make a request for BADA via the BADA User Interface here .
BADA Technical Documentation and Datasets
Licensed BADA users can find documents and datasets via the BSA application here .
Other publicaly available technical documents listed here can be made available on request by contacting the BADA Support Team.
User Support Tools
In addition EUROCONTROL makes these web applications available to support the use of BADA:
|BADA Calculation Tool||This web-based application provides Aircraft Performance Calculation (APC) allowing the calculation of aircraft performances based on BADA for all flight phases under various conditions with input chosen by the user. It also provides some additional calculation functions such as speed conversion, transition altitude calculation between CAS and Mach and synonym search mapping. The BADA Calculation Tool can be accessed here.|
|BADA Support Application (BSA)||
The BSA web application is a main communications channel between BADA licensed users and the BADA Team. It allows users to report issues with aircraft performance model, to ask questions and follow up status of developments. The BSA also serves as a repository of BADA related documentation and datasets.If you’ve already been granted access to BADA you may report an issue with BADA aircraft model or address a clarification inquiry to BADA expert by using the BADA Support Application (BSA) directly accessed here.
