Experts find faults on two more Lion Air Boeing 737 MAX 8
Jakarta - Inspectors have found flaws in two other Lion Air Boeing 737-MAX 8. A flight data display problem found on one of the planes might be similar to one reported in the previous flight of crashed Lion Air MAX 8, experts warned. (airlinerwatch.com) المزيد...Sort type: [Top] [Newest]
How much do these Boeing Aircraft cost , you sure think that in this day and age the planes should be able to compare the data between two instruments and not put the plane in stall mode .this need to go back to Boeing as a design issue.
This article really doesn't offer anything relevant. Thumbs down!
It is starting to appear that the 737 Max design was rushed to compete with Airbus and even Bombardier, the result is suspect because the promised performance is not materializing and cost of operation is higher than anticipated. As an example the overhead panel in the flight deck weighs 400 pounds compared to Airbus Neo at 40 pounds the nose gear had to be lengthened so the engines would not drag on the ground while taxiing. Just saying
I believe it has more to do with the stick shaker and auto response to lower the nose and adjust trim accordingly. Not good when a pilot has to fight his own aircraft for control.
In this year, with computers being smaller and cheaper than 50 years ago, we still use as main speed indicator the troublesome pitot tubes. That's mind blowing for me.
Airspeed could be easily calculated from GPS speed and altitude, corrected for air temperature. At least as back-up indication.

Flying out of Boston last week we were all on a Boeing 737 MAX 8. I wonder if we could have been in danger from the same faulty sensor, or lack of crew training, or a combination of both?
About three years ago I downloaded an app for my iPhone that computed my phone's altitude, GPS location, and velocity. As long as I held onto that phone I knew where I was relative to the earth and what my velocity was. With all the damage that pitoit tubes have caused (spider nest in pitoit tube brought down a passenger liner before) why can't we have that iPhone app in the cockpit for sufficient redundancy to give the flight crew enough information to save the plane?

And the opposite of what David outlined ...
Say your app shows a ground speed of 230 kts. Now what if the aircraft had a 115 kt tailwind? That means the aircraft's airspeed is 115kts - in a 737, that means you're spiraling out of the sky.

GPS will only give your speed relative to the ground. Proper airspeed is what keeps a plane aloft. If your airspeed is 400 kts and you are flying into a 100 kts headwind, your gps speed will be 300 kts. A helium balloon always has an airspeed of zero, but if it is aloft in the jet stream it’s ground speed (gps speed) could be 200 kts.
