A flying drone includes a flight control computer, a parachute system with a parachute, a power supply system, a propulsion system, and an actuating drive system, without any of these systems being redundantly duplicated. To prevent uncontrolled crashing of the drone due to a critical error of any subsystem, signals or data are supplied from the power supply system, the propulsion system, and the actuating drive system, to an error detection or recognition device, which detects defined errors or error combinations in the provided signals or data and then supplies a deployment signal to the parachute system, which responsively generates a control signal that triggers an ejection mechanism to eject the parachute.

1. A method of deploying a parachute from an unmanned drone air vehicle having a single power supply system without redundancy, a single propulsion system without redundancy, a single actuating drive system without redundancy, and a parachute deployment system with a parachute, comprising the following steps:a) providing respective signals or data respectively from said power supply system, said propulsion system and said actuating drive system, to an error detection device; b) evaluating said respective signals or data in said error detection device so as to detect if said respective signals or data correspond to at least one of defined error conditions or error condition combinations; c) responsive to detecting that said respective signals or data correspond to at least one of said defined error conditions or error condition combinations, providing a deployment signal from said error detection device to said parachute deployment system; d) causing said parachute deployment system to deploy said parachute in response to said deployment signal; and e) landing said unmanned drone air vehicle by descending with said parachute deployed, in response to said deployment signal.
