Did see this.. One of the plane’s so-called black boxes—the cockpit voice recorder—was recovered Wednesday, according to reports. The flight-data recorder hadn’t been located as of Friday afternoon Eastern time. How long do you think an aircraft accident investigation takes? Normally on aircraft of this size IIRC it would be somewhere between 6 to 9 months, though a preliminary report will be out in a week or 2. A lot depends on the damage to the CVR and the DFR and if China has the full facilities to read and understand them. Perhaps they may need to go to the USA, to the labs there or at the Boeing plant facility there. The initial report will rule out many things, such as a wing or the tail coming away. If large items like this are missing from the crash site then the investigators will follow the debris trail back to find them.

Popular Post aussiexpat Posted March 27, 2022 Popular Post Share Posted March 27, 2022 (edited) Just to clear up the number of B737-800 crashes, the 13 mentioned are accidents with fatalities, and 2 of those were B737-700 (1 of which was an emergency landing, not a crash) Of the 11 B737-800, one was shot down by Iran, one was a mid-air collision, 2 overshot the runway, 1 undershot the runway and 1 skidded off the runway so that leaves 5 'others' There are also 8 other B737-800 accidents with no fatalities, 3 overran runway, 1 undershot the runway and 3 skidded off the runway and 1 pilot landed on his nose wheel which collapsed IMO, that's a pretty good safety record for over 7000 aircraft over 25 years https://en.m.wikipedia.org/wiki/List_of_accidents_and_incidents_involving_the_Boeing_737 Edited March 27, 2022 by aussiexpat 5 Link to comment Share on other sites More sharing options...
billd766 Posted March 27, 2022 Share Posted March 27, 2022 21 hours ago, Moonlover said: So am i right in thinking that you believe that 360kph is a reasonable speed for an aircraft with no engine power in a vertical dive? If so I'm not going to argue with you. In fact I'll even offer you a possible explanation. One of the pilots spooled down the engines and put the aircraft into a vertical dive, That's literally engines off, nose down! Does that keep you happy? Of course it could have been a fault in 1 engine and the captain may have ordered the wrong engine to be shut down. Now that would be a WAG, a Wild Anus Guess. That may have been a reason, but more likely a stab in the dark, and I wouldn't believe it myself if I hadn't said it. 2 Link to comment Share on other sites More sharing options...

cjinchiangrai Posted March 27, 2022 Share Posted March 27, 2022 On 3/26/2022 at 6:42 AM, pacovl46 said: I don't think it was suicide because of the "slow" decent of the plane. 6000 meters in a minute equals 360 kilometers per hour, which is essentially terminal velocity for a plane falling nose down straight out of the sky, which makes me think that the engines must have failed because at full throttle that plane could've easily done 1000 kilometers an hour going straight down. Of course there's always the possibility that the pilot wanted to prolong the misery. Engine failure at 29000 feet gives plenty of glide time to get to an airport. It was definitely not that. 2 Link to comment Share on other sites More sharing options...

It's been known to have happened at least twice. British Midland Airways Flight 092 in 1989 and TransAsia Airways Flight 235 in Taiwan in 2015. But they were both low level with no time to recover the situation. This wouldn't be a problem at cruising altitude. 2 1 Link to comment Share on other sites More sharing options...
BusyB Posted March 27, 2022 Share Posted March 27, 2022 10 hours ago, Stargeezr said: Considering there was no communications from this jet liner, makes me think that something serious happened to knock out the ability for the pilots to communicate. I do hope that the flight data recorder will give good data. If a voice recorder is also located at the tail end of the aircraft, then we may get some date. It sounded like the one black box they found was very damaged, so hope they can still get the data. It was a tragic crash. If they weren't in some way disabled the pilots were too busy struggling with the plane to think about putting out a distress call.

SomchaiCNX Posted March 27, 2022 Share Posted March 27, 2022 On 3/26/2022 at 9:57 AM, Sydebolle said: Point taken but the 800 series was a quick-and-dirty fix against the competition. If, with capital letters IF, the media is telling us something faintly close to the truth then this particular flight had a more than senior cockpit crew of three seasoned pilots. One had booked 6,000 flying hours as captain and the other fellow with more than 20,000 hours; no details were available about the third captain (unclear also, why there were three pilots on this aircraft). Suicide seems, to me, out of the question and something very, very serious went wrong and it has all the patterns of what brought down the 737-MAX. Reason enough for me to not board such a plane until it is clear, what happened to those 132 souls .. You should get a job with TAT so that you get paid to tell BS. And nothing to do with the Max, different planes. 2 Link to comment Share on other sites More sharing options...

BS The glide ratio of these planes is x2 + more than a regular Cessna 172. The dreamliner even has around 20 to 1 that means for each km of height it can glide 20 km. So 10 km is about 200 km in distance that's enough to reach an airport in most cases except if your are over an ocean. But then again, Capt Sully dit prove that you safely can land an airplane without engines. What you described happened in Taiwan with an ATR 42/72 at low altitude a couple years ago.

The speed measured in Flightradar is horizontal ground speed , not speed in general . Even the horizontal ground speed exceeded the max of 540mph ( 590mph) .

The initial report said something along the likes of the plane having lost 6000 meters of altitude in one minute. That would be a speed of 360 km/h. Where did you get the 590 knots of terminal velocity? I don't think a plane can reach 590 knots without engine thrust, even if it goes nose down.

You have to stop banging on about 6000m in 1 min = 360 km/h as fact. It has been pointed out many times that planes send live data and this shows aircraft reached 590 knots at one point (approx 1090 km/h) Here is the actual data with yellow line showing the varying speed.

Ironically Paco the latest rendering of the evidence is right there in your very own post above! Go back up there and take a look at the 'Flightradar' data. Scroll down to 06:21:45Z (that's GMT by the way). Now look across. The aircraft is at 7,850 ft and shows an airspeed of 590 knots. That's its terminal velocity. It then begins to slow down again because it is coming into denser air, hence more drag. Now if you want to dispute that, take it up with Flighradar. I've had enough of this nonsense. 2 Link to comment Share on other sites More sharing options...

Anyway they have found the CVR so all may be revealed soon. https://en.wikipedia.org/wiki/EgyptAir_Flight_990 I'm suspecting "pilot-intervention" as the cause.
