KLM Boeing 787 and IndiGo Airbus A320 involved in a grave airprox incident on Friday, said the Aviation Safety Net on Twitter. An airprox incident is a situation wherein the safety of the aircraft gets compromised due to the estimation of either the pilot or an air traffic services personnel. It may also happen due to the distance between aircraft as well as their relative positions and speed. According to reports, the incident happened near Jaipur.
KLM B789 was flying from Amsterdam to Kuala Lumpur while the Indigo Airbus A320 was travelling from New Delhi to Bengaluru. Aviation Safety Net further reported that the Indigo flight 6E977 was operating on ATS route Q23 and climbing to Flight Level 350. While crossing ATS route L333 East of waypoint INTIL, it came in close proximity with flight KL811. The KLM Dreamliner was following route L333, at FL350.
The required standard lateral and vertical separation was reduced to 3.6 NM (6,67 km) and 200 feet (61 m) respectively. Vertical separation was re-established when the IndiGo flight descended passing FL342 for FL340 and KL811 was climbing passing FL353 for FL360. Both aircrafts continued to their destinations for safe landings. The Air Accidents Investigation Branch classified the occurrence as a ‘serious incident’ and started an investigation.
