I never disputed that Lubitz killed himself and his passengers.

On the previous flight, the following facts can be noted:

ˆˆ at 7 h 19 min 59, noises like those of the cockpit door opening then closing were recorded and corresponded to when the Captain left the cockpit; the aeroplane was then at cruise speed at flight level FL370 (37,000 ft);
ˆˆ at 7 h 20 min 29, the flight was transferred to the Bordeaux en-route control centre and the crew was instructed to descend to flight level FL350 (35,000 ft), an instruction read back by the co-pilot;
ˆˆ at 7 h 20 min 32, the aircraft was put into a descent to flight level FL350 , selected a few seconds earlier;
ˆˆ at 7 h 20 min 50, the selected altitude decreased to 100 ft for three seconds and then increased to the maximum value of 49,000 ft and stabilized again at 35,000 ft;
ˆˆ at 7 h 21 min 10, the Bordeaux control centre gave the crew the instruction to continue the descent to flight level FL210;
ˆˆ at 7 h 21 min 16, the selected altitude was 21,000 ft;
ˆˆ from 7 h 22 min 27, the selected altitude was 100 ft most of the time and changed several times until it stabilized at 25,000 ft at 7 h
24 min 13;
ˆˆ at 7 h 24 min 15, the buzzer to request access to the cockpit was recorded;
ˆˆ at 7 h 24 min 29, noises like those of the unlocking of the cockpit door then its opening was recorded and corresponded to the Captain’s return to the cockpit;
ˆˆ at 7 h 25 min 32, the flight was transferred to the Barcelona en-route control centre and the crew was instructed to descend to FL170;
ˆˆ at 7 h 26 min 16, the aircraft was put into a descent to its newly cleared flight level and the flight continued normally.
Due to the engaged autopilot modes, the changes in selected altitudes described above did not influence the aircraft descent flight path.

At around 1:33 in that youtube video, Tim Van Beveren, is saying that he believes Lubitz was dialling down the Altitude in the FCU on way to Barcelona, to see the optimal descent point / profile, this was regarding what happen on the previous sector to BCN.

Really clutching at straws these people.
These people are in serious denial regarding what happen.

Being a Boeing driver I am confused by the above statement that "the changes did not influence the descent path".

If the descent was initiated to FL 350 and 100 feet selected "in the window" the a/c would continue as commanded towards FL350, but, if the "window" height was increased, as suggested, to 49000 feet, on a Boeing, the A/P would have discontinued the "v-nav" descent and reverted to "Alt Hold". Surely the same would have occurred on an Airbus!

Over to you bus drivers...

Mode reversion, yes - but to SEL V/S of the moment when the ALT selector goes through the currently passing level / altitude.

Anyhow, the question is why did Lubitz fumble around with the ALT SEL knob?

In ALT mode, you can move your alt bug as much as you want, nothing will happen until you push or pull it.

Yeah, but he was already in a descend.

German airlines drop safety rule prompted by Germanwings crash
3 hours ago

From the section Europe
Germanwings has now merged with Eurowings

German airlines are dropping safety rules brought in after the 2015 Germanwings plane crash which require two people in the cockpit at all times.

Andreas Lubitz killed 150 people by crashing the plane - apparently on purpose - after the plane's captain left to use the toilet.

Airlines now say the two-person rule has no safety benefits.

Eurowings, which merged with the Germanwings brand, is one of the airlines now dropping the requirement.

The German airline association BDL announced the change, which will come into effect by 1 June, on its website. It said its airlines will be re-introducing their original cockpit safety procedures.

The European Aviation Safety Agency, which was behind the original rule change, relaxed the requirements last year to allow individual airlines to evaluate their own safety needs.

BDL said that its airlines had "independently" reviewed the rules and decided that the two-person rule had no safety benefits - and could actually be more dangerous.

The group said the changes caused "more frequent and predictable" opening of the cockpit door and expanded the number of people with access to the cockpit.
Safety rules about cockpit access were enhanced following the 2015 crash

It also said that the risk of a similar incident to the Germanwings crash was extremely low, and the risk of criminal or terrorist activity was much higher.

Lufthansa, the country's biggest airline, is one of the groups removing the requirement. Its airlines include Austrian Airlines, Swiss Airlines, and Eurowings - which was merged with Germanwings in 2015, a process which had begun before the company's high-profile crash.

Nothing that observers didn't say on the very day they said they would implement this rule.

Bad choices, but I agree with that conclusion.
