  • 1 Prevention using drones

    But flying a device at these altitudes is complex... According to the initial results, these drones flying at high altitude should have around a thirty meter wing span and weigh around ten metric tons
  • 2 Looking to the future

    Existing craft, flying at low altitude, are particularly suited to long-duration flights at low or zero cruise speed. Stratospheric dirigibles, still to be designed, would constitute an alternative or complementary solution to satellites, for high-altitude observation
  • 3 The Aircraft Collision Avoidance System FLARM, Patented by ONERA, Has Become Mandatory for Gliders

    Flarm installed above the dashboard of an ASW19. The enlarged view of the Flarm dial indicates that another glider is in front, flying at a lower altitude, invisible. This firm decision was taken following the tragic crash on May 5 2012 between a glider and a tow plane near Paris
