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.

The invention provides a TCAS (Traffic Collision Avoidance System) airspace situation monitoring capability improvement method, which comprises the following steps of: obtaining response of a target aircraft by passively receiving position broadcast of the target aircraft in an airspace and actively inquiring the target aircraft, so as to periodically obtain basic information frames such as distance, height, orientation and the like of the aircraft in the airspace; using the obtained target aircraft information frame to judge whether the target aircraft is in a local aircraft monitoring range, and if the target aircraft accords with the local aircraft monitoring range and an initialization condition, establishing initial tracking for the target aircraft; consistency discrimination is carried out on the target aircrafts which have established initial tracking, and if it is judged that multiple tracking aircrafts belong to the same target aircraft, the tracking aircrafts are reserved and abandoned; and converting the monitoring mode of the target aircraft according to the airspace situation, the data quality and the monitoring capacity condition. And traffic situation awareness enhancement and anti-collision warning services can be provided for the aircraft in operation.

The airborne intelligent anti-collision lamp is mounted on a low-altitude aircraft platform and used for sending an aircraft photosensitive signal according to an airborne anti-collision optical communication encoding format so as to send position, speed and attitude information of the low-altitude aircraft; the foundation basic type intelligent anti-collision lamp is installed on a ground object and used for sending a ground object photosensitive signal according to a foundation anti-collision optical communication encoding format so as to send the position and outer contour information of the ground object where the foundation basic type intelligent anti-collision lamp is located; the ground-based comprehensive intelligent anti-collision lamp is installed on the highest ground object in a preset area range, and is used for sending a ground object photosensitive signal according to a ground-based anti-collision optical communication coding format, receiving an aircraft photosensitive signal sent by a low-altitude aircraft in the preset area range, generating an in-area air traffic sketch map, and sending the in-area air traffic sketch map to the ground-based anti-collision optical communication coding format. Broadcasting a traffic sketch photosensitive signal according to the broadcast anti-collision optical communication coding format number; and the airborne intelligent anti-collision lamp is also used for receiving the ground object photosensitive signal and the traffic sketch photosensitive signal and automatically carrying out low-altitude traffic anti-collision. Automatic anti-collision information communication based on anti-collision light communication can be realized, the equipment is simple, the cost is relatively low, and technical support is provided for improving the safety of low-altitude flight.

The ParaDrop Operation Transponder (100) is a device that increases safety, visibility, and separation of paradrop operations by aircraft and air traffic controllers at high-volume airports and remote off-airport DZs (drop zones) for use at all altitudes and during night and day operations. The ParaDrop Operation Transponder (100) provides aircraft the ability to avoid parachute canopies utilized during high speed free fall, all weather and / or night operations. When the aircraft cannot physically see the parachute canopies, the aircraft can still locate the ParaDrop Operation Transponder (100) location on their traffic in-cockpit screens in real time. The GPS transponder (700) within the device is an ADS-B / Mode-S out device that enables the aerial jumper (90) to be detected by Secondary Surveillance Radar (SSR), Traffic Collision Avoidance Systems (TCAS), and ADS-B IN receivers.

The invention provides a civil aircraft automatic emergency descending process management and control system and a control method. The system comprises an emergency descent process traffic conflict handling device which is configured to receive traffic conflict alarm information from a traffic collision avoidance system (TCAS) in an emergency descent process, generate a comprehensive emergency descent avoidance route plan based on the traffic conflict alarm information, and synchronously execute conflict avoidance and emergency descent; the emergency descent process manual interruption handling device is configured to receive a termination instruction input by a pilot through a hardware switch and automatically generate a descent-to-level flight transition plan after emergency descent is terminated; and the emergency descending end-to-level flight transition process device is configured to automatically generate a level flight transition path plan based on the current flight state when the target safe height is reached, and maintain the level flight state to wait for a pilot to take over.

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.
