The Boeing 737 Max
Whatever anyone does don't get on one of these  |

First full hull loss of the 737 Max type since their inception in 2011 ,was the Jakarta flight that disappeared shortly after takeoff from Jakarta Indonesia in Oct 2018 ,it was a few months old 737 Max 8 ,this flight (Ethiopian )had a similar profile before crashing and was also a few months old ,neither flight gained much height and both crashed nose down at similar speeds of around 380kts (430mph) .A system called Maneuvering Characteristics Augmentation System (MCAS) has come under scrutiny after the loss of two planes and 338 life’s in as many months .

A software fault???....rigorously tested I assume...but twice failed in operation, not always easy to find software faults
I hope they withdraw it |

Been grounded.

They've got 4,700 orders for these 737-Max types. They come in three slightly different sizes the 7,8,9 and 10.
Our airlines fly them, whether there are significant technical differences between the models isn't stated. It's the Max-8 that's come down. |

Yes I know. |

Not picking doc, it was just a lovely set up and execution. Made me giggle.

Ryanair have got 135 of these on order.

O'Leary has sent Boeing an email.
Holy mother of Jesus, what's this load of **** you're sending me? Get your ******* act together you bunch of ****** ******! |

If you will buy a 1960s' design that has simply had new bits of kit strapped to it, Michael!
 There's no way the current 737s would get certificated were it not for the grandfather clause. |

I hear survivors are thin on the ground.

Well no offence PP, but that's all you're good for anyway. |

A system where the computer can override the pilot and will cause a crash if the sensor is wrong is imho totally unacceptable, it shouldn't be allowed. The pilot should always be able to take full control. Sensors giving bum info have caused numerous crashes before, e.g. that air france flight from brazil that went down over the atlantic. There have been others, I watched a program a few months back where they'd merely hosed down a plane to clean it, driving water into the sensor which then froze once it had got cold enough (remember it's very cold when a plane is at altitude, -50C or so) and again, bang.

If a plane isn't far off the ground, either taking off or landing and the anti-stall control cuts in and dips the front of the plane then its curtains.
Apparently on the first disaster with the 737-Max, the anti-stall control cut in 20 times during the flight. |

Should have the black box results fairly quickly, apparently.

I wonder what they'll decide to tell us?
With 4700 planes either in service or on order, they won't be in a hurry to release anything to the public. One investigator has already said that the two incidents seem very suspicious, he said things like this don't happen with new planes. |
|
By:
1000s on order, but only 100s in service, and 2 have crashed in what appears to be similar circumstances, of very new planes.
2 out of just hundreds crashing over a short time is surely hugely statistically significant. According to wiki they've only been in service since 2017 and only 350 delivered. I wouldn't fly on one until they fix this, that's for sure. |

By:
The footage on TV of the crash site is like it came down vertically, just a small crater and tiny bits left. At least it'll have been instant for those on board...

Quite incredible this fault was not found in testing????????
A system where the computer can override the pilot and will cause a crash if the sensor is wrong is imho totally unacceptable, it shouldn't be allowed I agree just checking |

By:
I am glad it was quick as well just checking....better than being burnt to death.

Boeing have issued a software update "Designed to make a safe aircraft even safer"

There shouldn’t be any software on the aircraft

Traditional aircraft the pilot flew it and had direct control of the rudder ailerons flaps elevators everything on the aircraft was within his control and he had to be able to fly and it gave the understanding of what exactly was happening and what was wrong when things went wrong and how to react
Now with fly by wire the automated system comes between the pilot and the aircraft systems and when something goes wrong they don’t know what to do They are also employing the wrong people as pilots now which doesn’t help either |

Precisely. |

This sensor issue is quite incredible; if the plane is rising at too sharp an angle then the engines are in danger of stalling, so the sensor causes the plane to dip in order to prevent that.
If there's a fault in the sensor it could dip the nose of the plane at any time. Which happened 20 times during normal conditions on the flight of the first one that came down as I mentioned earlier. They also had a problem with the height indicators when they were coming in to land, so they didn't know the height of the plane. I know an airline pilot just retired, he's always saying how these planes fly themselves. Which is startling. |

Supposedly a CAA ban on 737 MAX aeroplanes from UK airspace is in the pipeline.

By:
In aviation terms, 'stalling' in an aviation sense *usually* refers to a wing stall (not engine), Dr C, where the airflow passing over the wing stops generating lift, causing it to drop and control to be lost.

all 737 or just those with the wrong kind of pilot

Pretty rude to blame the pilots given no information at all that they've done anything wrong.
Apparently to fit the big newer more efficient engines they had to fit them further forward than they'd normally want to, which causes weird effects that can cause the nose to rise, so they've "fixed it in software" so the plane can try and trim the nose down all by itself if it thinks the nose is rising. This is imho bad but I find hard to forgive is that apparently they are so confident this is fantastic and don't want to confuse pilots, they omitted talk of this feature and any way you might override it in the official pilot manual. So a big **** you to boeing for THAT one. From what I've read about the flight logging the plane was picking up speed but not height which might indicate just this sort of problem (again). Though how that ties with the eye witness saying it was smoking and spinning, and other flight data that seems to show a lot of climb data at the end, who knows. Maybe there was some overreaction to it wanting to nose down and desperate measures meant it went up to enough to actually stall, which could lead to a spin. Suffice to say they should be grounding them until they know, I think it's reckless to keep flying them. |

Technology in theory makes the aircraft easier to fly , until something goes wrong
now I think that’s the wrong way round |
