There have been articles on the web about the Angle of Attack sensors disagreeing with each other, as is the case in both the Oct 2018 crash in Ethiopia, and the March 2019 Lion Air crash. Also pilots reports where there were uncommanded runaway Stabliser with "Near to a Crash" where the US...
Yes, this is true about the "Stability Trim" system working in the background on the 737NG, and also "Rudder Stability" during heavy Cross-Wind also work's in the background.
The bottom line is that the 737NG's are among the safest Aircraft in the world with a crash rate of 0.06 per million...
The difference between Auto Pilot and MCAS is the Human Pilot engages the Auto Pilot, where MCAS engages without consent of the Human Pilot or Co-Pilot. MCAS is supposed to work in the background. Now that Boeing has "Watered Down" MCAS so that it will NOT engage if the two Angle of Attack...
I agree with everything Artis said. Not just the above quote. When Alan Alda playing a US Senator in the 2004 movie "The Aviator" asked Howard Hughes if hiring Prostitutes, and paying for Fancy Hotel rooms and dinner's for US military officials could be considered "a bribe," Leonardo DiCaprio...
The photo of the side view of the 767-300 shows the Engine maybe 6 inches ahead of the forward edge of the Wing to Body join. The 737 Max 10 is closer to 2 feet ahead of the forward edge of the Wing to Body join. See photos.
Why is it necessary? The mere fact that the 767 and 757 passed the FAA required Wind Tunnel and Flight Testing, and the lack of MCAS, and the decade's of safe flying all point to a well designed aircraft, where the Max is not. Back in the 1980's this was common knowledge to Boeing employees like...
Reply to PeterDonis'questions:
The 757 and 767 Engines are not above the wings, and forward of the Center of Gravity, as is the case with the Max Aircraft. Yes, I could of been more clear. The conclusion that I made that the Max Engines are improperly placed causing Flight Instability, and Stall...
Answer to PeterDonis' questions:
1.) The 757 and 767 did NOT have the Engines forward of the Center of Gravity.
2.) What FAA tests did the Max fail? FLAGNOTE 04.) Of the Reference section above in: 14CFR §25.203 Stall characteristics. See above for details.
Please read entire Reference...
MCAS, MCAS, MCAS...The flight instability with the 737 Max is structural. The problem was caused when Boeing placed the Larger CFM LEAP Engines forward and up in front of the Wings where they should NOT be. This caused the Max to fail the required FAA Flight Tests. What Boeing should have done...
Yes, I think the Boeing Company would be in a very steep dive toward bankruptcy, if they do not consider the long term affects of their tragic mistakes with the 737 Max.
I do not think they are considering the solution suggested by EASA. No, I think they will pursue the MCAS, muscle it through...
I have 29 year's in Aviation Quality Assurance, 19 year's with Boeing.
MCAS is a Patch or Band Aid solution to the problem created by moving the larger Max jet Engines forward and up in front of the wing creating inherent Aerodynamic instability in the flight characteristics of the Max. This is...
