Unlike other ACASs (ACAS II, ACAS X), ACAS Xu can provide both vertical and horizontal resolutions. The challenge is: how to choose between vertical and horizontal maneuvers? The choice is done by a module called Nucleus. However, little information on what Nucleus might be was publicly available until last September.
Drones regulation is quickly evolving with a notable increase in complexity as more mission types appear, technology advances and public acceptability evolves. Complying with the regulation is complexe enough in a single country, and it gets even more complex for cross-border missions.
The EASA recently released some results from the “Drone Collision” task force. The goal of this study was to assess the potential risk to aircraft posed by drones of different sizes flying at different levels.
After the « Introduction of a regulatory framework for the operation of drones », the EASA is now proposing a complete prototype regulation for unmanned aircraft operation (all categories, all altitudes).
