Method for autonomous controlling of an aerial vehicle, wherein a flight operator commands the aerial vehicle, comprising the steps of: measuring flight and/or system data of the aerial vehicle; performing an evaluation of a flight condition of the aerial vehicle based on the measured data and based on at least one decision criterion; and, issuing at least one autonomous controlling command, if, as a result of the evaluation of the flight condition, the aerial vehicle is in danger; wherein the at least one autonomous controlling command issued comprises at least one of: an emergency route command that selects an emergency route, wherein the emergency route permits the aerial vehicle to land as soon as possible; a crash route command that selects a crash route, wherein the crash route permits the aerial vehicle to go to a next reachable crash site; an alternate route command that selects an alternate route, wherein the alternative route is prepared regarding changed air tasking orders, changed mission objectives or changed airspace coordination orders; or an approach and landing route command that selects an approach and landing route; wherein the evaluation of the flight condition of the aerial vehicle is performed via a traffic alert and collision avoidance system of the aerial vehicle; wherein the measured data of the aerial vehicle includes flight data of the aerial vehicle and system data of the aerial vehicle, and wherein data regarding at least one of: altitude, airspeed, ground speed, flight path of the aerial vehicle, weather conditions parameters, air temperature, or wind speed, is used as the flight data of the aerial vehicle for said performing an evaluation of a flight condition of the aerial vehicle; and wherein at least one of: health information of engines, health information of a flight control computer, or health information of further units of the aerial vehicle, is used as the system data of the aerial vehicle for said performing an evaluation of a flight condition of the aerial vehicle. measuring flight and/or system data of the aerial vehicle;
