President Pakistan Aerospace Council, Dr. Haroon Javed Qureshi, offering his Technical Analysis in a Television Show on Recent PIA 8303 Tragic Airplane Crash
Dr. Haroon Javed Qureshi (PhD), President Pakistan Aerospace Council was invited in a television show “Halqa-e-Ahbab”, telecasted on 29 May, 2020 at Roze TV to present his technical analysis on recent PIA airplane crash.
Giving his analysis, based on analysis of the flight data logged by ADS-B (Augmented Dependent Surveillance – Broadcast) data received by ground receivers from the actual flight, and ground to Air Voice communication also recorded by ground receivers.
Dr guarda ora. Qureshi feels that the extremely steep descent of the ill-fated aircraft from 10000 ft to 3500 ft at speeds over 250-275 knots and then from 3500 ft to the runway at around 170 knots with vertical speed of descent of over 33 ft/sec (2000 ft/min), instead of the expected 10 ft/sec (600 ft/min).
The aircraft possibly never got to lower the landing gears initially, as the Airbus 320 does not allow the landing gears to open at speeds of over 260 knots, to avoid structural damage and during the last 90-100 secs of flight, for the first attempted landing, due to the reported steep angle of approach i.e. 3000 ft at NM instead of normal 1000 ft, there is a possibility that the pilot could not lower the landing gears fully and the aircraft touched down with engines scrapping the runway 4500-5500 feet from the threshold intermittently; serious breach of cockpit SOPs and some lack of enforcement of SOP at the ATC possibly cased the tragic crash.
Though the analysis of the CVFDR recovered from the ill-fated aircraft will validate this analysis or otherwise: Watch the detailed analysis here.
