Base of aircraft data

Realistically model the performance of any aircraft


Your air traffic management (ATM) research and development activities require modelling and simulation tools capable of replicating real-life operations and aircraft performances as realistically as possible. This is why, at EUROCONTROL, we spent decades building the most comprehensive and accurate aircraft performance model in the world.

Perfecting our advanced skills in aircraft performance modelling and working closely with aircraft manufacturers and operating airlines, we built base of aircraft data (BADA), which provides theoretical model specifications and related specific datasets to accurately simulate the behaviour of any aircraft.

Replicate the performance of any aircraft

Based on the best available aircraft performance reference data, BADA enables you to realistically reproduce the geometric, kinematic and kinetic aspects of your aircraft’s behaviour over the entire operation flight envelope and in all phases of flight.

With BADA 3, you can access model specifications for nearly 100% of aircraft types in the ECAC area.

If you need highly precise data for modelling and simulating advanced systems and future concepts, BADA 4 currently covers 80% of aircraft types.

Leaders in aviation

BADA is the international reference for aircraft performance modelling for the purposes of trajectory prediction and simulation.

We provide BADA to the international aviation community - a large user community comprising research institutions, universities and air navigation service providers (ANSPs), as well as ATM suppliers - in addition to using it ourselves.

BADA model options

Today’s standard for aircraft performance modelling which provides coverage close to 100% of aircraft types in the ECAC area. Its objectives are to model accurately aircraft behaviour over the nominal part of the flight envelope and to meet today’s requirements for aircraft performance modelling and simulation.

A newly developed model family covers 80% 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.

These tools are not developed by EUROCONTROL, but other companies who have obtained permission from EUROCONTROL to integrate BADA in their Tools. Acquisition of these Tools require prior EUROCONTROL permission and a licence agreement for BADA. By completing one of the associated request forms, you are requesting this permission. If approved, the Tool provider will be notified and act accordingly  with the tool deployment process. Note that by this licence you will not obtain direct access to the BADA data files. The Tool will be provided to you by the Tool developer/owner.

Access procedure

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.

In order to request a BADA licence, you must:

  1. OneSky Online account
    Register to EUROCONTROL’s OneSky Online – your secure path to may of EUROCONTROL’s online tools and dashboards, including BADA.
  2. Log in and access the BADA User Interface
    Once you have created an account, log in to OneSky Online and you will find the ‘BADA User Interface’ in the list of tools you are given access to – click on it to request a license.

NOTE: The creation and authentication of your account and its synchronisation with the BADA User Interface may take up-to 30 min.

BADA's growing community

Becoming a BADA user means joining a close-knit community of operational experts and researchers from across the entire industry, from air navigation service providers to aircraft manufacturers and R&D bodies.

Each year, you’ll be invited to take part in the BADA User Conference, an unprecedented forum for learning, exchanging and networking with like-minded ATM specialists from around the globe.

“The BADA conference provides users with a way to interact directly with other professionals who use the BADA tools. This interaction is not just through the presentations and question-and-answer sessions of the conference, but also at breakout working groups where participants can directly engage with other people working on the same types of aviation issue. In addition to interactions with the other users, the developers of BADA are available for discussion on any technical or policy topic related to the BADA tools. BADA has become an integral part of the FAA’s aviation environmental tools in part because of the openness of the developers to working with the users, as exemplified by the BADA conferences.”

David Senzig Electronics Engineer, U.S. Department of Transportation

“During the conference, it is gratifying to see that BADA stands at the heart of a cooperative network that brings together aviation industry players, air traffic management operators and R&D entities. Thanks to everyone’s active involvement, BADA is constantly evolving to fulfill and anticipate user requirements. Each year, we enthusiastically prepare two days packed with interesting and relevant information about BADA and its applications.”

More than just conferences, the interactive workshops are devoted to discussing technical aspects of BADA, making the model more user-friendly and generating synergies with fellow aviation professionals – with plenty of time for participants to present their projects and innovations.

Open to licensed members, as well as other industry experts, this pioneering event defines the future of aircraft performance modelling, while fostering close inter-professional connections and generating immense personal and professional satisfaction.

Upcoming BADA User Conferences will be listed here and in our Events section, where you can find all of our upcoming events and meetings.
