The Directorate General of Civil Aviation (DGCA) has identified a jumbo jet of Taiwanese carrier Eva Airline as the aircraft that caused turbulence on a Jet Airways flight when they crossed paths on July 21.
Replying to a query in Parliament on Thursday, Civil Aviation Minister Vayalar Ravi said the jumbo plane that passed by the Jet Airways flight was identified as a B744-747 aircraft. The jumbo, flight EVA 6079, belonging to a Taiwanese carrier, Eva Airline, was flying 1,000 feet above the Jet Airways Delhi-Guwahati flight in the opposite direction.
“Both the aircraft were flying in RVSM airspace and there was no breach of separation,” Ravi told the Rajya Sabha in reply to a query by Ishwar Singh.
RVSM refers to the reduction of the vertical separation between two flying aircraft, which is mandated at 1,000 feet.
The DGCA, the air safety regulator, said it was not an incident but an ‘occurrence’.
“All operations were normal. There was no injury to any passenger or crew,” Ravi said, and added that the Jet aircraft, carrying 134 passengers, experienced a “moderate wake turbulence”.
Wake turbulence is the disturbance caused by a bigger plane flying nearby a smaller plane.
The “occurrence”, the minister explained, was investigated by an Inspector of Accident appointed by the DGCA.
