MIDCAS is the European Detect & Avoid project

The MIDCAS project is laying the groundwork for future developments in the field of RPAS air traffic integration. The project has gathered European industries within the field of D&A with the purpose to achieve jointly agreed results with European and global standardisation stakeholders.The MIDCAS project was launched in 2009 by five contributing Member States (France, Germany, Italy and Spain under the lead of Sweden) under the framework of the European Defence Agency, with a total budget of 50 million.

MIDCAS has been carried out by an industrial consortium composed of 11 partners: Saab (project leader) from Sweden, Sagem and Thales from France, Airbus D&S, Diehl BGT Defence, DLR and ESG from Germany, Alenia Aermacchi, Selex ES, CIRA from Italy and Indra from Spain. Throughout the project, external stakeholders such as EASA, EUROCONTROL, EUROCAE or JARUS, were involved in the process.

The MIDCAS project is designed with focus on 3 main tracks with high level of interaction and interdependency:

  • Progress on Standards for D&A
  • Design of a generic D&A function to be tested in simulations
  • Design of a D&A Demonstrator to be tested in manned and RPAS flight

The aim of the MIDCAS program is to contribute to the RPAS integration in civilian airspace by proposing a baseline of solutions for the "Unmanned Aircraft System Mid-air Collision Avoidance Function" acceptable by the manned aviation.

The main MIDCAS functions are:

  • Situational awareness for the RPAS pilot
  • Traffic Avoidance function (or Self Separation)
  • Collision Avoidance


MIDCAS ensures a continuous dialog with all players of the aviation community and organisms in charge of aerial safety in order to favor the acceptance of the proposed solution by this community.

MIDCAS is the biggest project funded by the European Defense Agency, supported by the Ministries of Defense (MODs) from five European countries and led by a consortium including 13 European companies. They hold a large portion of European knowledge on Sense & Avoid as well as on other technologies relevant for the project.
