what is wrong with you yoruba muslims.

Even if Nigeria had an airline, I would rather travel by road.

And I was in that plane o, how I manage to survive is what I can't explain.....praise God

TourismMan:
So what is now the interpretation/meaning of the pitch up pitch up to a lay man understanding?

Sholaco:
What is pitch up again, is that the only information they got from the black box

Americans and their media have since been looking for ways to paint Ethiopian Airlines and their personnel as negligent and untrained in order to absolve Boeing of any blame.

This is ridiculous.

Not necessarily.
Preliminary investigation showed that the problem was faulty sensors triggering the MCAS. The result would be pilots fighting with computers. MCAS triggers nose down while the pilots fight to bring the nose up. Man vs machine--who wins? The results are there. That's why Boeing came out with software patches to fix the bug. But trust American spin doctors, they will find a way to railroad the argument to pilots' fault. But the truth is very vivid to all discerning minds.

Neoteny:
The plane was nose-diving, the Pilot Flying was being told by the other pilot to rotate the plane upwards ("pitch up" ) to avoid the dive. Pitching is rotation along the X axis in the 3 degrees of motion of flight, with the others being yaw and bank.

The 737 MAX is an extended range version of the 737NG with bigger engines which are placed forward. With that configuration, the plane has a tendency to pitch up when in thrust. The MCAS helps to stabilize flight by pitching the nose down. It also assists in stall conditions.

A stall is a situation whereby a plane losses lift (or the ability to remain aloft) due to slow speeds or an increased angle of attack whereby the winds rushing over the wings are not enough to maintain lift. Ideally, in a stall condition, the pilot simply pitches the nose down at speed such that more air would rush over the wings and create lift. MCAS helps by doing this automatically, unfortunately in the case of the two 737MAX accidents, MCAS behaved erroneously due to wrong sensor data and pitched the nose down into a dive, and seemed to refuse the pilots the ability to override the system. Boeing claims that there is a procedure to override MCAS, but a lot of pilots were not trained in this procedure.

Hope this helps.

Thank for this explanation!
Now I see why people are trained to use both manual and automatic while driving just in case the automatic fails!

The plane was moving normally but the software was wrongly forcing the nose down. So the pilot was saying "pitch up" i.e. drag it up to counter the effect of the anti-stall software.

Gain altitude! The aeroplane was already looosing height.. hence the reason he said pitch up!!

It's clear this accident was caused by the auto trimming software MCAS , we have seen auto trimming softwares work aerodynamically unstable military planes like the B2 and F117 who wouldn't be able to even fly without such softwares working overtime to create input aerodynamics and stabilization but bringing such software into commercial aircraft to augment poor aerodynamics should be discouraged , commercial aircraft must depend on traditional aerodynamics as it's foundation and only use trimming software as minimally as possible ..The 737 max problem started from the moment the Boeing design team decided to ignore traditional aerodynamics in a bid to force in the CFM Leap turbofan engine into their aircraft to beat time and protect it's market from the encroaching Airbus A330 Neo the CFM engines were larger than what the low fuselage of the 737 could handle so the opted to move the engine further out the wings to create suitable clearance from the ground , this change will greatly change the aerodynamics of the 737 causing it to tend to pitch up during a flight which if unchecked could lead to a stall , so BOEing introduces MCAS which they have used on various military flying wing prototypes to come in and automatically pitch the planes nose down any time it's notices on over pitch upwards , the problem is that MCAS must work in tandem with a couple of sensors most important which is the Angle of Attack swivel sensor and if these sensors sends any faulty info to MCAS the software is also bound to overreact like what we saw on both crashes where the softwares thought the plane was going into a stall and attempts to recover the plane by pitching down and increasing engine power ( pilots would understand this ) but the problem here is that the plane was not stalling like the software thought but only climbing during the take off phase .


Way out for Boeing now .

I am a die hard fan of the 737 family and I consider it the safest commercial plane ever made and the most successful but in the wake of the recen crashes of the the Max series this what I think Boeing can do .

1 .shop for a smaller engine with the same performance spec as the CFM 1B leap.
OR
2.Re design the 737 so it can accommodate the CFM Leap engine .
OR

3 . Make MCAS to be redundant during the take off and landing phase of every flight and only active at cruise altitude .

Neoteny:
Ideally plane systems are not supposed to fail, due to multiple redundancies, but when they do pilots are usually trained on how to use checklists and experience to safely land, or control-crash the plane if needs be.

However, Boeing really screwed up on this plane, and it's so sad about 350 had to lose their lives before a fix comes.

I think in the short term the 737 Max is doomed.
