The hero was the pilot of an Air Seychelles Airbus A330-243 operated as HM 54 flying from Mauritius to Seychelles. In trouble is the pilot of Emirates Airlines, flying an A380 super jumbo as EK703 from Dubai to Mauritius.
These are the words of Mauritius Air Traffic Controller to the Air Seychelles Airbus 330 pilot the most likely largest civil airline disaster was avoided two days ago over the Indian Ocean on an air route between the Seychelles and Mauritius:
The Emirates Airline pilot will be in trouble if I file a report. If you are not filing a report I will close the matter as well.
The report was filed anyway – and the outcome is pending.
An Airbus A380 Super Jumbo operated by Dubai based Emirates Airlines, and an Airbus A330 operated by Air Seychelles almost collided, if it wasn’t for a quick heroic action by the Air Seychelles Pilot.
Both crews were visual with each other, received TCAS resolution advisories, in addition HM-54 turned right. Position data off transponders of both aircraft shows that the horizontal separation between the aircraft was about 7.5nm when both aircraft passed through Flight leval 360 at 0 feet vertical separation and was about 4nm when the vertical separation between the aircraft reached 1000 feet again with EK-703 below FL360 and HM-54 leveling off at Flight level 370.
Here is what happened:
On 14th July 2017, Emirates 703 (EK703) an Airbus A380-861 from Dubai (DXB) to Mauritius (MRU) was cruising at an altitude of 40,000 Feet before requesting descent to Mauritius for Runway 14. Seychelles 054 (HM054) an Airbus A330-243 was leaving Mauritius for Seychelles and given clearance by Mauritius ATC to climb and maintain 37,000 Ft. Upon requesting descent, EK703 was given clearance to descend and maintain 38,000 Ft due to crossing HM054 at time 13:07(UTC). EK703 read back Flight Level 360 (36,000 Ft) to Mauritius ATC instead of Flight Level 380 (38,000 Ft).
