Sama, eikä pelkoa helpota lentoturmatutkintojen seuraaminen.
Tämän tutkinnasta:
"737 sits so low to the ground (a deliberate design choice to let it serve small airports with limited ground equipment), Boeing moved the engines slightly forward and raised them higher on their underwing pylons. (If you place an engine too close to ground, it can suck in debris while the plane is taxiing.)
That new position changed the aircraft's center of gravity, creating the potential for the nose to pitch up during flight. Boeing designed software called the Maneuvering Characteristics Augmentation System, or MCAS, to overcome this action. When a sensor on the fuselage detects that the nose is too high, which could eventually cause the plane to stall, MCAS automatically pushes the nose down.
Investigators in the Lion Air crash have said that a fault in the the sensor may
have been feeding incorrect data to MCAS, pitching the nose down into a dive. According to the investigation, the Lion Air pilots struggled to take control of the plane before the crash as it pitched up and down. (For a thorough explanation of MCAS,
see this story from The Air Current.)
On Nov. 6,
Boeing issued a safety warning advising 737 Max operators of the potential for a sensor failure and instructing them how to deactivate MCAS by flipping a switch. But two days later,
The Seattle Times reported that Max 8 pilots were not specifically trained on using MCAS."
Jos vaikka tieto vähentäis tuskaa... Eilen oli töllössä joku meikäläinen asiantuntija ja oli näillä linjoilla kanssa, automatiikkaa ei voi edes ohittaa ja lentäjiä ei koulutettu siitä, saattaisivat myös taistella sitä vastaan jossain vaaratilanteessa ja pahentaa asioita. Nyt pitäisi olla tiedossa nämä lentäjillä. Tietty jos viallinen sensori voi väärällä datalla syöksytttää koneen maihin niin aika hurja visio. Luulis että joku muu systeemi tulis ja override tuosta ettei maihin mennä.
