A SriLankan Airlines Airbus A330-200 performs an emergency descent over Bangalore, India while on route to Pakistan.
The SriLankan Airlines Airbus A330-200, registration 4R-ALS was performing flight UL-1183 from Colombo, Sri Lanka to Karachi, Pakistan.
The A330 was cruising at FL400 90nm Southwest of Bangalore, India when the flight crew initiated an emergency descent to FL110 with a descent rate of 4,100fpm.
The aircraft then initiated a return to Colombo, Sri Lanka. The flight crew climb back up to FL120 on route back due to mountainous terrain over Kochi, India and later descended back to 10,000ft.
The crew landed safely in Colombo, Sri Lanka 80 minutes after the initial emergency descent.
An emergency descent is a maneuver carried out by the flight crew which involves the aircraft descending as rapidly as possible to a lower altitude.
The maneuver is mainly performed due to a loss of cabin pressurization, uncontrollable fire, or any other event that requires the aircraft to descend to a lower altitude at the earliest possible time within the structural limitation of the aircraft.
There are set procedures the flight crew should follow under company operating procedures which are set by the guidelines of the aircraft manufacturer. Flight crew are routinely trained to perform this maneuver if ever necessary.
