PIA A320 Crash Karachi
A teardrop maneuver might have been the ticket to a possible survival in this case. Gear up is a good question. Dpends also when they did extend it. If it was down during the whole circuit it could have made a difference same as config and speed. Best glide speed clean vs. flaps 3 and gear down at 150kts will lead to a significant change in glide ratio. But that is a moot point. Don't smash the donks in the first place. Otherwise you're purely down to luck and minute details which could be easily figured out in hindisght from the comfort of your armchair...
No one with any airline experience needs an altimeter with needles to tell them they are way out of the groove if they are at 5nm at 3500ft. Given that it appears they were at 210kts or so, even throwing an orbit would have left them hard pressed. Maybe a subtle incapacitation, but what of PM.

What do you guys think is the significance of the exchange during the 1st approach.where they say they are established on the localizer for 25L, ATC says 'turn left heading 280', they then repeat that they are established on the localizer with no further comment from ATC ? If they were truly on the localizer and flying 250, then 280 would require a right turn. This seems odd.

Has anyone analysed previous approaches to this aerodrome by PIA flights on Flight radar 24 ? Perhaps it may show that the airline is quite accepting of un stabilised / super steep approaches ?

ATC was trying to vector them to give space as they were high. But they said they are already established. It could be a case of false glideslope because while ATC was very uncomfortable with their position pilots were totally at ease. Similar thing happened in AI Express crash at Mangalore India.

That being said, a significant turn like that after already having given approach clearance if just bizarre. Why didn't ATC just cancel approach clearance if they were (rightly so) concerned about the safety of continuing this approach?

Similarities AIE Mangalore & PIA Karachi.

Both these cases , the pilots seem to be out of the loop and decide to go around after the initial touchdown which in hindsight seems to have more of an effect on the lives lost ironically..
Also , the CVR in AIE showed the copilot announcing go-around but the captain continued and the copilot did not assert himself , the DGCA eventually came out with a circular on subtle incapacitation and the mangalore crash is often cited in CRM and pilot training modules at Indian carriers .
Let’s wait for the CVR/FDR data and investigation reports to get the HF info on the PIA crash . Sad day for aviation .

Below is a link to an article, “Pitch-up Upsets due to ILS False Glide Slope.” Conducted by the Dutch safety Board.
IMC I could see a false 6 or 9 degree capture going unnoticed for a short period but VMC probably not.

If you're high and fast 'gear is your friend" when you're trying to manage your total energy from a 'too much' to a normal energy profile. Going 'downhill' at 210 kts, along with being high on the glideslope, the plane will not slow down, or at least not quickly, without gear.

Without speculation where is the shared knowledge, the brainstorming, the "I never in the world would have thought of that", the fodder for some crazy movie? Would not one expect that engineers designing the next generation would be reading all of the speculative ideas which then might enter the FMEAs of the next gen? The master button that will light up indicating the airplane thinks you are doing something stupid, are you sure you want to do this knowing that I (the plane) think your actions may cause a crash? Press here to continue your foolish action for which you assume total responsibility.

With the degree of automation in aircraft these days, coupled/interfaced with automatics minded pilots, i doubt this accident would have happened if it was left totally to the automatics. Put another way, the humans interfered and screwed it up, for reasons we are not aware.
Man is fast becoming the weak link. We all know we are not going to elimate human error. I'm a dinosaur but even i can see what's happening and what the trend is.

According to Pakistani media channel ARY ATC approach and tower controllers have given their statements. According to them pilots ignored their warnings at 10nm about being high and fast. Trying to manage that they forgot the gear and landed first time with gear up.

I understand and agree with you. I was replying to the comment that on an approach to RWY 25, a turn to 280 would be a right turn. ATC actually said "turn left to heading 180". Whoever wrote the text on the video got it wrong and wrote 280.
That being said, a significant turn like that after already having given approach clearance if just bizarre. Why didn't ATC just cancel approach clearance if they were (rightly so) concerned about the safety of continuing this approach?

They went from 2000’ to 100’ in 1.4 minutes, while slowing down from 240 to 210 kts.
That is about 1500’/min, while slowing down.
I don’t think the ‘bus would do that, without some gear assistance.

Well while I would agree with you in general but strange things have happened also in VMC. Air India Hong Kong incident was in VMC the crew was specifically asked by ATC whether they are aware about GS fluctuation. And yet in 10km visibility the aircraft pitched down 2nm before FAP and descended at 2700ft/mt. then settling down at ROD of 2000ft/mt. The crew didn't notice a thing till at 300ft over the sea when the GPWS sounded they looked outside and went round. It was a narrow escape. So anything is possible.
