Exercise Albatross 2023? These will be “ parachuting[s] with drift under high finesse canopy and oxygen ". On this occasion, a Temporary Regulated Zone (ZRT) was created which occupies a large part of Center-Val-de-Loire. It will be active from Monday 6 to Friday 10 November 2023 then from Monday 13 to Friday 17 November, from 13:00 p.m. to 17:00 p.m. (12:00 p.m. to 16:00 p.m. UTC) and from 20:00 p.m. to 23:00 p.m. (19:00 p.m. to 22:00 p.m. UTC).
As usual, since activation times are difficult for the general public to know, it is recommended to refrain from flying with a drone in the ZRT when it is potentially active.
