Recently Two IndiGo flights boarded with around 328 passengers got pretty much close in order to form a mid-air collision. Both the planes almost have crashed into each other if the pilots on both the aircraft would not have taken emergency evasive manoeuvers to avoid the disaster.
The news says that both the planes were of IndiGo airlines and both of them shared the same category which is Airbus A-320s. These planes were operating on the Coimbatore-Hyderabad (6E-779) and Bangalore-Cochin (6E-6505) routes respectively. While on their respective routes the pilots of the flight were warned by the cockpit alerts regarding the collision which made the pilots take the defensive measures in order to avoid the collision.
One of our sources even said that both the flights were traveling at some hundred kilometers per hour and were less than 8 kilometers away from each other when the cockpit alert made the pilots aware of the situation. Our sources further added that both the aircraft were vertically separated by just 200 feet as they headed towards each other.
The near-miss between both the flights took place when one of the aircraft was ordered by Air Traffic Control to reach to 36,000 feet while other was asked to climb to 28,000 feet. Besides pilots attempting to reach the desired heights, there was a stage when the flight, 6E-779 was at 27,300 feet and 6E-6505 was at just 27,500 feet with both aircraft headed towards each other.
“The TCAS-Resolution Advisory system was triggered on two of our aircraft operating Coimbatore-Hyderabad and Bangalore-Cochin routes respectively on July 10. Following normal procedure this has been reported to the regulator,” the airlines said in a statement.
A news says that IndiGo airlines after this incident are not answering queries that have been put up by the media regarding the incident and neither the airlines are sharing the details on how close the aircraft were to each other.
The traffic collision avoidance system which is abbreviated as TCAS is the last defence against mid-air collisions that is used by the aircraft. This defence system generates advisory instructions to what to do immediately in the form of loud automated voice commands.
In order to avoid collisions, TCAS systems have been used by all civilian airliners operating in India as a mandatory system which detects signals from other aircraft through a transponder.
