This invention provides a method for reducing disruptive alarms from the Terrain Awareness and Warning System (TAWS), comprising: using a Terrain Collision Avoidance System (TCAS) to identify the presence of other aircraft within a first horizontal range and a second range below the aircraft; generating a first signal in response to the identification of other aircraft within the first horizontal range and the second range below the aircraft; and providing the first signal to the TAWS to suppress alarm signals issued by the TAWS. Furthermore, this invention also provides a corresponding apparatus. With this invention, disruptive alarms from TAWS GPWS Mode 2 can be effectively suppressed when an aircraft passes overhead causing a jump in radio altitude.

This invention relates to the fields of unmanned aerial vehicle (UAV) technology and air traffic safety management, and discloses a simplified airborne collision avoidance system. The system includes a processor, a memory, and a communication interface. When the processor executes a computer program, it implements a multi-source perception and fusion unit, a trust assessment unit, a cooperative mode management unit, and a graded avoidance decision-making unit. It achieves compatibility with existing unsigned broadcasts through graded verification, marking targets with different trust levels and adjusting risk assessment weights accordingly. It identifies authorized targets through authorized cooperative modes, dynamically lowering safety distances or alarm thresholds within the authorized range, and distinguishing between non-contact and contact cooperation. It generates cooperative or non-cooperative avoidance commands through multi-level progressive risk assessment. It supports parsing dynamic sweep area description information from rotating obstacle broadcasts and reconstructing time-varying collision envelopes. This invention is flexible in deployment and can be installed on various aircraft and ground obstacles, improving low-altitude airspace collision avoidance safety.
