What a bad PR !!
They basically say that the crash of this week could have been avoided !!
The causes of the Ethiopian crash are not known yet and cannot be « only » due to that MCAS thing!

“Ever since the Lion Air crash, Boeing has been developing a flight control software enhancement for its Boeing 737 MAX type, designed to make an already safe aircraft even safer,” the U.S. aircraft manufacturer announced. The FAA says it anticipates mandating this software enhancement with an Airworthiness Directive (AD) no later than April. Boeing have worked with the FAA in development of this software enhancement.

The update includes updates to the Maneuvering Characteristics Augmentation System (MCAS) flight control law, pilot displays, operation manuals and crew training. The enhanced flight control law incorporates angle of attack (AOA) inputs, limits stabilizer trim commands in response to an erroneous angle of attack reading, and provides a limit to the stabilizer command in order to retain elevator authority.

Let's not jump to conclusions.

A software update goes through multiple iterations, unit testing, integration tests, validation tests and qualification tests before being released and distributed to the airlines. This can take MONTHS.

This is the aviation industry and critical software we are talking about. Not a Facebook app software patch...

This can still be the SW patch for the first crash...

Unconfirmed: Australian CAA to ban 737 MAX from its airspace.
The Australian Civil Aviation Authority has just suspended any Boeing 737 MAX aircraft from flying into or out of Australia due to safety concerns following the Ethiopian air disaster. Two foreign airlines fly these aircraft types to Australia.

TUI fly BE only has 4 B737-MAX 8 aircraft.

Grounding 4 aircraft would not wipe them out... the PR however...

The other issue in the industry is that many airlines discourage manual flight. Some pilots count way too much on automation and are therefore weak in manual flight skills. Good luck to recover from such a situation (unreliable airspeed + runaway stabilizer) if you basically never fly manually (or only when the plane is perfectly in trim and on speed...).
chinese authorities have required airlines to fly manual below FL100.

True, but the half of their short-haul fleet is flying in North America at this moment... Finding alternatives will not be that simple...

Oman is the first country in the Gulf to ban Boeing 737 MAX jets from operating to/from the country. The Sultanate of Oman has grounded Oman Air’s 737 MAX fleet.

And probably he's right, but I don't fly the plane until Boeing has implemented the modifications.

Now UK CAA has grounded the 73M as well. Am I the only one in thinking the aviation authorities know more than we do? I cant be just public pressure?

Hello

it also states the similarity of both crashes... and even other operators with 737max are not allowed to fly to the UK anymore.

Greetings,
All my posted timings are local !

If this continues like that TUI Belgium/Netherlands might be the sole company flying the birds in this region since their sister company in the UK can't fly them either due to the blanket ban of the CAA in the UK.

Unrelated (but not totally): Lion Air (Indonesia) is considering switching to the A320 family, including the A321neo, amid plans to suspend existing orders it has with Boeing. The carrier is suspending delivery of four B737 MAX it had on order for 2019.

Piet Demeyere, spokesman of TUI Belgium: "We are aware of media reports that the CAA has ordered that all 737 MAXs remain on the ground. We are evaluating these new facts and are not commenting at this time. As soon as we have more information, we will come back to you."
