Abstract

L'invention concerne un procédé et un dispositif de commande de vol pour un véhicule aérien sans pilote, un procédé et un dispositif de surveillance de vol, et un support d'informations lisible par machine. Le procédé de commande de vol comprend les étapes qui consistent : à acquérir une distance de vol d'un véhicule aérien sans pilote (étape 10) ; à acquérir, selon la distance de vol, des informations d'environnement de vol du véhicule aérien sans pilote (étape 11) ; et à générer des informations d'avertissement lorsque l'existence de risques de sécurité est déterminée en fonction des informations d'environnement de vol du véhicule aérien sans pilote (étape 12).
