A last minute alert from the anti-collision device mounted on aircrafts helped avert a mid-air collision after a Jet Airways flight from Chennai came close to an Air India aircraft over Mumbai on July 10.

The Jet aircraft, with 142 passengers on board, was asked to descend to 11,000 feet by the Air Traffic Control.

It came close to the Air India flight that had 70 passengers on-board and was also on its way to Mumbai from Chennai.

The Traffic Collision Avoidance System (TCAS), a hi-tech system designed to reduce the incidence of mid-air collisions between flights, on both the flights alerted the pilots of the intrusion in their path.

As a rule, two aircraft are required to maintain a vertical separation of 1,000 feet and a lateral separation of five-miles.

If any aircraft breaches these limits, the TCAS sends out an alert. In the present case, the two aircrafts were less than five miles apart laterally. The Directorate General of Civil Aviation (DGCA) is investigating the matter.

“Our commander was alerted by the aircraft’s technological system well in time about the presence of another flight in its vicinity while approaching Mumbai,” said an Air India spokesperson.

Jet Airways said that the incident took place while holding over Mumbai under Air Traffic Control instructions.
