Best Case: Protective Measures in Place

• Technical measures: A rule set implemented in the drones' technical system prohibits them from flying closer than five meters to people and attacking them. In addition, the rule set prescribes a minimum distance from the ground. If the "normal zero" value is manipulated by the malware introduced and the drones lower themselves, sensors (ultrasound or radar) immediately report that the prescribed distances have been undershot. As a consequence, a set of rules takes effect that is isolated from the rest of the system and cannot be overprogrammed.
• Organizational measures: The rule set that takes effect in the critical case is certified and, ideally, has been developed and installed by another manufacturer.
• Consequences: The rule set forces the drones to slow down and ensures their uniform, safe descent. No persons are harmed.
