Ethiopian Plane Crash
- Thread starter Darts
- Start date
I've had hundreds of flights on 737's & never a problem its a workhorse of the industry. After the first crash Boeing issued a emergency service bulletin to all carriers on how to train pilots to turn off MCAS if they encountered a problem. Let the legal battle ensue...RIP to those poor passengers
No it's not.
Different engines, wings. New glass cockpit for flight instruments.
But same systems, and still paper checklist, not electronic. Everything manual, like putting generators on the bus after start, and configuring the pneumatics for start and after start. Same as 737 made in 1970.
The problem exists with the autopilot off. With a high angle of attack approaching stall, the stabilizer trim starts trimming nose down to prevent the stall. That's ok when the everything is working ok.
The problem arises when false high Angle of Attack signal is sent to the flight control system, that then automatically starts to trim the stabilizer nose down, and the more the pilots pull up on the elevator as a result, the worse the nose down trim. Procedure is to place the stabilizer cut off swithched to the cut-off position, thereby deactivating the stabilizer actuator. The stabilizer can then be manually trimmed using either of the trim wheels on either side of the pedestal.
But try doing that just after take-off without much room to manoeuvre, and if you've never practiced it before. All you know initially is that the airplane wants to pitch down and initially, you're trying to pull back trying to avoid auguring into the ground. They're going to incorporate this item in the training.
BTW, the 737 hand flies like a shit box.
This is the only article I read on this accidents.

Looks like AI is killing people.
Then after almost every country grounds these jet for further investigation, the Canadian government proudly stands by the same jet.
Like ... duh!
:Eek:

This latest crash is bad news for Rolls Royce.
The Coventry based company has a twin hydra to deal with: the looming Brexit (Coventry voted to remain) and United Technologies Corp in the jet engine field. The current Congress wants to break up the conglomerate, apart from jet engines it also owns Otis Elevator, and Carrier HVAC. Long in the shadow of GE, the company has left Edison's company in the dust since 2016. Now it wants to cut Rolls Royce down to size.

Hmm. Talked to a commercial pilot and it would seem that the problem is related to MCAS- which he thought that it was weird because it only comes on at high G loading or near stall. Conditions that the airline pilots avoid. The problem might be as simple as inadequate training in a transition to an upgrade.

Man the plane really augered in. Nothing but a hole in the ground, quite spooky really. @ 1:12 on the vid

When MCAS works, its fine, when sensors go bad or how it reacts to anomalous readings then its dangerous. MCAS does not activate when flaps are down, but what happens if the flap sensor fails (as I suspect it did in this case) then it will push the planes nose down just after takeoff..as it appears happened in this case.
Man so glad most of you are not working on this investigation.
It's a horrible tragedy it shouldn't happen, but I am certain there was no intent in causing harm.
All of you get into your car every day, drive and don't give it a second thought to the fact that you are now facing your greatest odds of dying.
The 737 is a great plane had one of the best safety records in the world.
They will get to the bottom of the problem make the plane safer. Nothing in this world is perfect, but we always do our best to learn from mistakes and improve.
I type here with my Pixel 3 phone and I hate the auto correct. I type one thing and this stupid thing writes another. AI it's in its infancy, but just fearing a product those not make it better. We are better than AI and always will....

Minister Garneau is announcing restrictions on flights of MAx 8 into and out of Canada. Sounds like the prudent thing to do until the investigations in the two crashes are complete.
Update: Just watched CP 24 interviewed a retired 737 pilot.
1) He said there were several "near death" experiences in addition to the two crashes.
2) Hard or impossible for pilots to kill the auto system and take manual control.
3) They might rename the 737 as it is now bad stigma.

union pressure was mounting. I cannot see any Airline pilot wanting to fly this thing everyday wondering when its gonna kill you. Air crew as well. They are not like most of the blissfully unaware public.
Air Canada made a HUGE mistake, shoulda bought A320 NEO. At least they bought Cseries. 60 at that !!!

That is true. While things can go wrong with computer software, this sounds like it's shaping up to be the perfect storm of conditions that caused these crashes. One thing is for sure, if they didn't have these super sophisticated aircraft and instead left everything in the hands of the pilots, you'd have infinitely more crashes.
Sounds like he's covering his ass. A MAX 8 crash here would sink JT's government.

It's official. MAX 8 grounded in Canada. That has to have a significant impact on AC and West Jet's fleet capacity, scheduling etc. Wonder how, if ever the restrictions will be lifted?

Note: Marc Garneau was the first Canadian astronaut and flew on the Space Shuttle three times.

According to the report the crash happened 6 min after take off. Plenty of time to override the system, if needs be. There's more to this story because it just doesn't make sense right now.
You buy a redesign from ANY manufacturer, there WILL be problems. Saying Air Canada should have bought the A320 NEO is armchair quarterbacking.
It takes 5 to 10 years to sort out new generation aircraft. Doesn't matter which manufacturer you select. Airbus, Lockheed, Boeing, Northrup, Leonardo, etc.
There are entire airlines that exclusively run 737's. WestJet used to until recently, and Southwest, who WestJet used as their business model, still does and uses 750 of them. These airlines are not going to switch.
The 100+ seat airline market is a duopoly between Boeing and Airbus. Airbus owns a substantial share of the Bombardier CS300 and Boeing owns Embraer now. Both Boeing and Airbus use the same subcontractors for parts like engines.
Flip a coin. They are equally bad or good.
