TWO IndiGo planes managed to avoid a collision in Guwahati, leaving some passengers and crew members shaken and leading to medical aid being provided, officials said on Wednesday. No casualties were reported and both flights made safe landings.
The incident took place on Tuesday evening when an IndiGo flight from Mumbai was about to land at the Lokapriya Gopinath Bordoloi International Airport, Guwahati. At the same time, an IndiGo flight bound from Guwahati for Chennai took off, crossing the flight path of the first aircraft. “IndiGo flight 6E-813 en-route to Guwahati from Mumbai experienced turbulence due to monsoon activity over the sub-continent, yesterday (August 2, 2016). Due to this monsoon activity, passengers along with the cabin crew on board were physically shaken,” said an official statement from IndiGo Airlines.
The type of turbulence could not be detected by weather radar, confirmed IndiGo officials. While four passengers complained of giddiness, two cabin crew were provided first aid after the turbulence.
“During such weather situations, there are two types of activities — first is ‘Cumulo-Nimbus’ activity and second is ‘Clear Air Turbulence’ (CAT). While the former can be detected by the weather radar, as per which the flight crew typically takes deviations and flies to avoid any turbulence, the latter is experienced occasionally and cannot be detected by the weather radar. 6E-813 flight experienced CAT which could not be detected by the weather radar. This caused the aircraft 6E-813 (Mumbai-Guwahati) to climb by about 250-300 feet, at the same instance another aircraft 6E-136 (Guwahati-Chennai) was crossing 6E-813,” stated IndiGo’s official statement.
“Following the prescribed protocol, the pilot immediately applied the Resolution Advisory (RA) triggered by TCAS (Traffic Collision Avoidance System). TCAS is on-board equipment that advises pilots about the traffic in the proximity of the aircraft and also instructs pilots in the avoidance action (Resolution Advisory) to maintain desired separation between the aircraft. Of all, four passengers complained of giddiness and two cabin crew needed first-aid,” read the IndiGo statement .
The airline said that passengers and cabin crew were immediately informed about the turbulence. A request for doctor and ambulance was made at the Guwahati airport. “The flight made a normal landing and immediately after landing, these four passengers along with the two cabin crew were administered with the necessary medical assistance. According to doctor’s report, there were no major injuries reported.”
