An Indigo Airbus A320 also performed an emergency descent over Bangalore this week
Earlier this week an Indigo Airbus A320-200, registration VT-ITM performed an emergency descent over Bangalore.
Flight 6E-6654 was a scheduled flight from Lucknow to Bangalore, India. The aircraft was cruising at 37,000ft about 160nm north of Bangalore when the crew initiated an emergency descent to 10,000ft due to loss of cabin pressure.
The aircraft leveled off at 10,000 in 6 minutes with an average descent rate of 4,500ftpm. The crew continued the flight to Bangalore and landed 30 minutes following the emergency descent. A SriLankan Airlines Airbus A330-200 also performed an emergency descent over Bangalore, India while on route to Pakistan on 3rd April.
The A330 was cruising at 40,000ft, 90nm Southwest of Bangalore, India when the flight crew initiated an emergency descent to 10,000ft with a descent rate of 4,100fpm. The crew returned to Sri Lanka.
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.
