Arrêté du 3 décembre 2020, annexe, point 2.6Version 1Effective -Verified 22 August 2026

In plain language

Your drone must either automatically stop itself from flying past the horizontal boundaries of your programmed flight area (even if you command it to or it is on an autopilot mission), or it must immediately alert you with an alarm if it crosses those boundaries.

Requirement as structured

The aircraft must be equipped with either an automatic device that prevents it from crossing the horizontal limits of a programmable flight volume, or an alarm system that alerts the remote pilot if such limits are crossed.

Original regulatory text

Un dispositif automatique empêche l'aéronef de franchir les limites horizontales d'un volume de vol programmable, même en cas de commande du télépilote ou d'activation d'un plan de vol automatique, ou un système d'alarme informe le télépilote d'un tel franchissement ;
