The incident took place on October 20 on flight 9W 332 around 8.50am, during the morning peak hour. The check pilot was flying as an additional crew member (ACM) in the jump seat located behind the pilots' seats. An ACM's status is that of a passenger and s/he is not supposed to touch the flight controls. ``The aircraft was established on the Instrument Landing System (ILS) for runway 27,'' an official said, implying the aircraft was coming in to land from the east and was about 3,700 feet high and had got visual guidance to help it descend and touch down on the runway 27 centre line.
In un ILS, 1000ft sono il massimo per considerare un'avvicinamento "stabilizzato" e per non far suonare i vari avvisi del GPWS
