Computer Error

it did have a proper de-icing system


so ice must've not been a problem, unless this system also is operated by the plane's computer, and if there was an error in the computer, it might've not detected the ice on the wings

On 15 August, authorities reported that the crash occurred just one minute after the plane began a steep descent. The pilots had indicated that the plane required "more power"

.

[Nicky91]

what if there are two causes linked to each other

Flight Computer Failure - Failure off the De-Icing System




requires more power, well if ice is on the wings, this might be a huge problem for the engines tbh, to keep generating lift and thrust




but then again, why did the pilots enter a region of icing in the first place, rather than going around it?

Brazilian 737 pilot here. That day i was flying from Argentina to Sao Paulo. I flew through that same area a couple of hours later. in the STAR towards sao paulo. There was a severe icing advisory in effect. While Descending below fl200 we got ice formation on our windshields and wings. A very strong weather system was arriving from the south that day. Rip all the souls and the brave brazilian pilots whom im sure fought all the way to the very end.

.

one of the comments below i shall highlight, another pilot who was also flying in that same region that day who also encountered those exact weather conditions


why would these pilots fly through that sort of severe icing?

a different story regarding the co-pilot, seems there were 2 lawsuits against him,

Termination of the Employment Contract

hmmmmm

[Nicky91]

might not mean that much since the captain's superb track record compensates for this, but still what was the first officer fired for?


also these lawsuits are not exactly from that long ago, May 2024 i can imagine him having been feeling quite some stress because of this, wanting to do everything perfect now

That should be checked
before the flight

FAB denies that TV Globo had access to the recording of the black box of the Voepass plane

and https://www.reuters.com/world/americ...on-2024-08-27/

the Brazilian Congress created a committee to investigate the crash which was to be formed by Voepass executives and representatives from ATR

Leonardo Ferreira was misidentified as one of the victims of this crash, he has confirmed he is not dead

nobody of that name was on the aircraft's passenger list

[Nicky91]

The preliminary report identified the following sequence of events (UTC−3:00):[47][51]

11:58:05 – aircraft takes off from Cascavel Airport (SBCA);
13:18:47 – aircraft communicated to the São Paulo approach tower (APP-SP) that it was at its ideal point of descent;
13:19:19 – APP-SP requested that the aircraft maintained altitude due to traffic, which temporarily restricted its descent;
13:20:33 – aircraft receives authorization to enter the SANPA position, maintaining altitude;
13:20:50 – the aircraft begins a right turn to the SANPA position;
13:20:57 – stall alert is activated;
13:21:09 – control of the aircraft was lost, the aircraft entered an abnormal flight attitude. At this point, the aircraft tilted to the left and then to the right. It then went into a "flat spin" until it collided with the ground;
13:22:02 – APP-SP made five calls to the aircraft, but received no response;
13:22:20 – the aircraft's recorders become inoperative;

seems there was a malfunction with the de-icing system? it got turned on, but also manually turned back off, that makes no sense to do such thing, what was going on inside that cockpit

also why would they fly through that area of severe icing between 12.000 and 21.000 ft, at an altitude of 17.000 ft, why not fly around it?

[Nicky91]

the pilot has enough experience, ok he's clear



but the first officer is the one who turned on and off the de-icing system, also if you de-ice your wings, there will be form a moist layer, turning it off, makes that wing freeze even worse, so there is a serious flaw in the de-icing system, but honestly no one should ever fly through severe icing, that is why it is very important to check the weather in flight, especially going through an important thing as take off/landing the two most dangerous moments in the flight

[Nicky91]

also more traffic delayed their descent, made the situation worse, having to stay in that area of icing for a longer amount of time


if they had been cleared to descent further to lets say 11.000 ft they would've had more chances of making it safely


also not much communication between likely the FO and ATC about this issue and the severity of the weather between those altitudes
