Re: PIA A320 in Karachi: loss of power after GA, crashed in residential area during final approach

Thank you. And,I didn't know either that the RAT powered the blue system or that it was unrelated to the gear extension. Perhaps they lowered it before losing all the engine-driven hydraulics, or perhaps they used the gravity back up. But they the gear was extended for sure shortly before the crash ...

Re: PIA A320 in Karachi: loss of power after GA, crashed in residential area during final approach

Flyboy, a couple questions if I may. Scenario: The pilot lowers the landing gear lever but the gear doesn't come down because the plane being faster than the gear extension speed limit. Questions: Is that scenario realistic? (i.e. will the plane "refuse" to lower the gear if you are going too fast? ...

Re: PIA A320 in Karachi: loss of power after GA, crashed in residential area during final approach

Did you really have to post when you did not_ (and I ass-ume could not_)answer the most important question? I've already said that I like pinapple on my pizza!!! Oh, the other question.... Well, not an answer really because, as you say, I don't have one, but... I also hear the rumor that the "sink ...

Re: PIA A320 in Karachi: loss of power after GA, crashed in residential area during final approach

If you descend from 5000ft to zero in about 2 minutes, you are going to get GPWS warnings as long as the system is working. There is no way that this descent will not be within the GPWS warning profile (first "sink rate" and then "woop woop pull up").

Re: SpaceX crewed demo mission

If you have enough money you can buy anything! 8-)

Kidding aside, I watched it and it was so cool I don't have words. I thought it was a tragedy when the space shuttle program ended with no replacement, and now in just a small way, things are more right with the world.

Re: PIA A320 in Karachi: loss of power after GA, crashed in residential area during final approach

No. Not_relevant. They arrive at 400 ft, stabilized and hit a storm. This does not address flyboy’s genius question of the millennium- What happened way earlier to get them high and flap and wheel limited? I agree it is not relevant too all that happened before the runway threshold, but it shows a ...

Re: PIA A320 in Karachi: loss of power after GA, crashed in residential area during final approach

My leading speculation at this moment is (I have other candidates): They came in too high and fast, forgot the gear up due to the overload during the "iffy" approach, no checklist or rushed checklist, and possible overlapping, disabling and/or misinterpretation of warnings, touched down too fast and...

Re: Hubristic approach angles...

I very much want to see flyboy's long-asked question answered: Why were they 2000 feet too high 5 miles out? Then, I will be more interested in all of the anomalies you keep citing. I agree. It seems that there are people out there with access to more ATC and ADS-B (radar) info that I could find. I...

Re: Hubristic approach angles...

If I'm on fire in 5 places, obviously things like stable approach criteria become not that critical. Further, 2,000' too high 5 miles out is not insurmountable and no, it shouldn't require anything crazy (maybe an S-turn) to get rid of. Should still be within Vapp+10-15ish at landing, which is tole...

Oh, great, exactly what we needed: On May 26th 2020 it became known, the data module of the cockpit voice recorder has not been found so far. Authorities are hopeful to find the CVR's data module during removal of the wreckage from the crash site. On May 26th 2020 a spokesman of the airline reported...

Re: PIA A320 in Karachi: loss of power after GA, crashed in residential area during final approach

We have very little idea what was going on, but the radio protocol was efficient. I am not so sure.... efficient is effective with minimum resources. The communication was quite "minimalist" so it would be efficient... if it was effective. If you are facing a situation so daring that you need to la...

My back-of-a-fag-packet chain of events above is based on the AVHERALD report, the photographs, discussion here etc.
And it is an excellent, complete and concise summary of the facts known so far.

Flyboy: So, 10 smartphone batteries burst into flames while you WAY high on downwind and the plane catches fire in 5 places (FA's valiantly extinguish 5 of the fires)...you declare an emergency and roll out on final 5 miles out, 2000 feet high... As the ISGPOTM, you recognize you are higher than wh...

Re: PIA A320 in Karachi: loss of power after GA, crashed in residential area during final approach

Another crazy hypothesis... They had problems with the nose gear and they went around normally (there are reports of a go around due to problems with the nose gear, but perhaps it was first go-around before a second one where they dragged the engines). They could not fix the issue and they decided t...

Re: PIA A320 in Karachi: loss of power after GA, crashed in residential area during final approach

As I'm sure you know, the 320 doesn't have TOGA buttons, and TOGA mode is activated by firewalling the thrust levers, so the "idle go-around" scenario doesn't strike me as particularly plausible unless they had the thrust levers at idle "post-touchdown" and didn't bother to advance them at all. If ...

Re: PIA A320 in Karachi: loss of power after GA, crashed in residential area during final approach

So something was wrong even before the go-around. Presumably the nose gear. Something else drew my attention on that recording: they were passing 3,500' at 5 miles out. KHI is at 98' MSL. Yes, that called my attention too, and the controller's too. When the pilots said that they were comfortable no...

Re: PIA A320 in Karachi: loss of power after GA, crashed in residential area during final approach

ATC recording from before the 1st go-around. The go around is just "going around". No reason, distance or altitude is mentioned. They seem to be having (and hiding) problems after the go-around. They were cleared to 3500 but ATC calls asking why they stay at 2000 and they say they will stay at 200. ...

Re: PIA A320 in Karachi: loss of power after GA, crashed in residential area during final approach

Couple of years ago there was a 777 accident where the pilots started the go-around by clicking the TOGA buttons but they did so a split second AFTER the plane touched down, that caused the auto-throttles not to go to TOGA (as they would have had the TOGA buttons had been pushed a split second befor...
