Changes coming at FAA after crashes, watchdog says
(CNN)The Federal Aviation Administration and an inspector general will signal changes to aviation safety oversight in the wake of two fatal Boeing 737 MAX 8 crashes, according to prepared testimony obtained by CNN for a highly anticipated congressional hearing. Dan Elwell, the acting FAA administrator, will tell members of the Senate Committee on Commerce, Science and Transportation's Subcommittee on Aviation and Space Wednesday afternoon that the agency's "oversight approach… (www.cnn.com) 更多...Sort type: [Top] [Newest]
I see everyone is talking about "software updates" I would guess most of us have been around the block with "software" with Microsoft and how RELIABLE software is this to me is not to bright. A slight mention of the AOS sensors is sounds like the real problem. Are these of a poor design that they are providing false info to the "software"? Are these sensors a complex "level". Sounds like a carpenter level in the cockpit would do the trick but to allow "software" to rule is NOT GOOD!
Microsoft has absolutely nothing to do with flight deck avionics, your analogy is bordering on the simplistic. Software in aircraft is updated all the time in accordance with established procedures by the airframe vendor, government regulators and component suppliers.
It is AOA sensor not AOS. Boeing's mistakes in this case was not using both AOA sensors but only one, inadequate Fault Tree evaluation of the MCAS system for single component failure and very poor training updates on the MAX.
In today's aircraft software rules, it is a fact of life and has been since "glass" flight decks were introduced. "Carpenters level", what a joke, never worked for a airframe manufacture have you. Nice try at trolling.

I read somewhere that the right side AOA was an accessory and would cost the buyer extra to activate. The right side AOA is in place because the 1st crash had the data in the black box. It was only the left side AOA data that had Electrostatic charges riding on the data. That almost indicate that the aircraft skin charges were entering the computer and activating the MCAS function. They need to find the basic fault of why the aircraft skin was conducting electrostatic charges into the AOA cabling. The new standard by Boeing will require both AOA data to be compared to prevent the MCAS system total control of the stall system. You are correct that the software changes are simple to install and require about 2 hours at most. It took us about an hour a bus to install all the route data changes.
I am honestly sorry to point this out, but... Weren't those 2 crashes outside of the U.S.? (Sorry for pointing the finger at other countries). Could it be that these countries need to revamp their flight instruction to not only keep up with the ever changing instrumentation, but for Boeing itself to send better instruction manuals on their upgraded instruments? I point out that the crashes occurred in other countries, only for the fact that, although I have heard of problems with the upgrades here in the U.S. but no actual crashes.
To me it's either the foreign countries not providing the best flight instruction, or Boeing not providing the best info on the new upgrades

John check out this article by a fellow pilot... He actually posts some NASA reports by US pilots complaining about the MAX doing stupid stuff and Boeing's training.

Ethiopia has a very good safety record... it's Boeing and the FAA
Does it not occur to you and the previous poster that US pilots experienced the same issues and responded appropriately? No absolution of Boeing or the FAA but a clear cut indication of the proper flight crew response resulting in a squawk as opposed to fatalities.
