Lion Airlines Flight 610 crashed into Indonesian waters as the pilot "lost the battle with his software," Canadian Transport Minister Marc Garneau announced a suspension of the Boeing 737 MAX 8 at a press conference on Wednesday.
There is nothing wrong with the basic machinery of the aircraft: its engines, wings and control surfaces are all considered to work properly.
On the contrary, the passenger plane may have killed 346 people because human pilots cannot drive a faulty computer, which is a terrible modern reason.
The reason for the lion crash-
The suspicious cause of the recent shooting down of Ethiopia Airlines Flight 302is a little-
Known software called MCAS, mobile feature enhancement system.
737 MAX 8 fuel is getting heavier and heavier
More efficient engine than the previous 737 version, this change caused the aircraft to tilt continuously upwardsso-
Slightly adjusted after takeoff
Instead of directing airlines to warn their pilots of this quirk, Boeing simply equipped MAX 8 with MCAS, a program that automatically leans its nose down to compensate.
The system is not a problem under normal circumstances, but turning MCAS into a fatal liability requires only minor maintenance errors.
In the case of lion Airlines Flight 610, the 737 MAX 8 has a faulty "angle sensor ";
A small blade sticking out of the cockpit, recording the angle of the plane in flight.
The sensor mistakenly told MAX 8's flying computer that the plane climbed much faster than it used to be.
As a result, the pilot wrestled with a plane that repeatedly fell to the ground for no reason.
The pilot can offset the dive by pulling the control column, but the MCAS will start again after just 10 seconds and tilt the plane down again.
"If this is not checked, it may lead to a situation where the potential nose is heavy, and it is almost impossible to lift the nose manually, business pilot and blogger Akan Bassey wrote in his November assessment of the Lion crash.
In fact, the last few minutes of the Lion Airlines Flight 610 show that when the pilot competes with the MCAS for control of the aircraft, the aircraft frantically turns up and down.
"In the conflict between software and pilots, planes tend to swing," Garneau, an experienced pilot, said on Wednesday.
In the end, Lion Airlines 737 tilted forward 26 times before the pilot finally lost control.
What's more confusing is that in-
The cockpit alarm and the wrong instrument readings made it impossible for the lion pilot to even know what was going on.
Pilots can take a series of complex steps to cover the MCAS system, but as the New York Times wrote in the analysis, "These steps are not in the manual and the pilots have not been trained by them.
The Wall Street Journal quoted a Boeing official as saying it was concerned about "bringing too much information to ordinary pilots ".
However, while the manual may not contain MCAS-
Specific instructions, a recent statement by Boeing wrote that their manual "has outlined an existing procedure that can safely handle erroneous data from angle of attack (AOA) sensors
"Pilots are always able to go beyond the flight control law using electric trim or manual trim," it wrote . ".
Part of the relative mystery of the MCAS is that it should not even be noticed by the pilot, because its design is only to start in a potential emergency.
The program failed-
If the plane is thrown too hard, it may be placed in a "booth", a safe box designed to save the plane;
In this case, there is no longer enough air flow on the wings to generate lift.
As Boeing wrote in a recent statement, "MCAS does not control aircraft during normal flights;
It improved the aircraft in Africa.
Operate the normal part of the envelope.
"Preliminary data from the crash of the airline's flight 302 showed the same doomed trajectory.
"Obviously --
Actually, for all parties
The trajectory of the carrier's flight is very close, and the behavior is very similar to that of the Lion airlines, "FAA acting chief executive Daniel Elwell said at a briefing this week.
The global grounding of 737 MAX 8 is different from the previous aircraft grounding.
Within a few weeks of leaving the factory, not only did 737 MAX 8 s crash, but there were signs that they did not have an obvious material defect.
MacDonald Douglas, DC.
Due to the possibility that the failure maintenance procedure causes the engine to be cut from the wing, 10 is grounded at 1970 s.
The Boeing 787 Dreamliner was rooted in 2013 due to its lithium.
The ion battery is on fire.
Most notably, the dehavelan comet split sharply in flight due to design flaws, so it was grounded in 1950 seconds.
But in the case of 737 MAX 8, the possible problem only exists in the programming of the aircraft, which raises concerns about the danger of excessive driving. automation.
Since the lion crash, Boeing has not properly informed them of the MCAS, and 737 MAX 8 pilots have been expressing anger, especially the possibility that this program may twist the control of the aircraft from the hands of humans.
"We don't know this MCAS even exist," an anonymous American airline pilot posted on an online forum . ".
"I 've been driving MAX-
It's been almost a year now, several times a month, and I'm sitting here thinking, what else I don't know "NASA maintained aircraft accident report database is full of multiple reports from the largest 8 pilots who actively tilted forward shortly after the plane took off.
One pilot wrote that special care must be taken when taking off to eliminate the "MCAS threat ".
Nevertheless, the pilot was still suffering from a "hopeless brief nose condition ".
In another article, one pilot called MAX 8's flight manual "almost a crime shortage" and complained that Boeing had left the pilot ignorant of how automated MAX 8 was.
"This plane needs such jury manipulation to fly, which is a dangerous fact," the report wrote . ".
