The Data Exchange working group can be understood as the association’s implementation body. It was launched in March 2017. The working group aims to make sure that all stakeholders defined in the UTM architecture document have the appropriate protocols to communicate electronically among one another when required. (Note that by definition, data exchange is limited to content and format; it doesn’t cover the infrastructure and data-link layers.)
The first output of the working group was a Flight Declaration Protocol, which facilitates the secure exchange of flight situation data between UTM providers. It was developed by the Altitude Angel team, which offered it to the Global UTM Association’s data exchange initiative in February 2017. The second protocol is the Flight Logging Protocol, headed by Yves Jusot and Samuel Dépraz.
The group’s governance is different from that of usual working groups. The technical steering committee is in charge of assessing proposals before they get to the working group and making sure the different protocols constitute a coherent whole. The project management committee is also composed of working group members, who are responsible for updating and growing a specific protocol according to the UTM community’s needs.
To encourage their broad adoption, protocols are indeed open, meaning organizations that are not members of the association can submit change requests and comments directly on a publicly accessible collaboration platform.
The technical steering committee is composed of Neil Kidd (Altitude Angel), Daniel Rubio (Airmap) and Koen Williame (Unifly).

The mission of the Architecture working group is to define a high-level architecture that is globally accepted by the industry and promoted to national aviation authorities as the basis of a standard UTM architecture. Its chair is Andres Van Swalm (Unifly) and its vice chairs are Stéphane Michaud (Viasat) and Kai Lothar John (GLVI).
The group published its first document UAS Traffic Management Architecture on April 29, 2017. It describes a high-level UTM architecture for Very-Low Level (VLL) operations, considering all types of UAS operations (VLOS, EVLOS and BVLOS) and the needs of both RPAS and autonomous unmanned aircraft. It also establishes a common terminology and a set of UTM stakeholders, with their needs and responsibilities.
This common framework should be a guideline to develop the association’s efforts to foster interoperable UTM, but also for the international or national bodies.
