TCAS helps avert collision between ANA jets near Tokyo’s Haneda
The aircraft passed with about 20 metres of vertical separation, and TCAS triggered a course correction that prevented injuries, according to flight trajectory data.
A near-miss on Tuesday near Tokyo’s Haneda Airport involved an All Nippon Airways (ANA) aircraft approaching from Shanghai coming dangerously close to another jet. The South China Morning Post said TCAS on the ANA plane warned the pilot in time to avoid contact.
According to flight trajectory data cited by the outlet, the jets crossed paths with about 20 metres (66 feet) of vertical separation. The ANA plane’s traffic collision avoidance system prompted a course correction, and no injuries were reported.
Industry professionals based in China told the South China Morning Post that the incident highlighted the importance of anti-collision technology and procedures. They pointed to the other aircraft’s system failing to deliver a comparable warning during the event.
The outlet also reported that it sought comment from ANA and the Japan Civil Aviation Bureau, but neither responded immediately. The professionals said China has stringent measures and systems intended to make similar occurrences less likely, framing aviation safety as important for Beijing’s broader aviation ambitions and domestic airliner development.
