Does the Flight Data Recorder consider the physical position of the fuel switches or does it get the information from some fly-by-wire part that could be buggy?

The conversation would suggest that the switches were in CUTOFF position, but there is also a display that summarizes the engine status.
There is no conversation that mentions flipping the switch to RUN again.
EDIT: Why is there no Cockpit Video Recorder? The days of limited storage are over.
- WalterBright 1y agoI've had discussions on HN with people who insisted that having a video camera always pointed out the control tower at the runway was some sort of impossibility. Despite every 7-11 having such a system. This would leave accident investigators with a lot of work to do to try to figure out how a collision happened.
- tekla 1y agoYes there is.

- ekianjo 1y agoAnd Pilots end up dead because of it.
- bombcar 1y agoAnd now some pilots are dead. Just allow cockpit video recorders, and if they're ever used for anything, the pilots (or their heirs) get $250k in cash.
- gnulinux996 1y agoAre you actually using a tragedy like this to launch an assault on organized labour?
- JumpCrisscross 1y agoWhy is that outrageous?
- Dylan16807 1y agoWhat, do you want them to hem and haw and refuse to answer? Saying the union drove a decision is hardly "an assault on organized labor".
- yard2010 1y agoYou have to admit this is a smart demagogue!

- nikanj 1y agoAirlines are decades behind on tech. You can get satellite internet almost anywhere on the planet and GPS can give you ten-foot accurate positioning, but we've still _lost_ planes because we haven't mandated a system that sends the realtime position of the plane over the satellite internet. The days of limited storage are still going strong in the industry.
- karlgkk 1y agoThere are reasons they don’t. This is a deceptively difficult problem Cost is a big one (satellite data is still quite a bit more expensive than you think, especially with many stations) And by stations, I mean aircraft. There are a TON. Current constellations probably wouldn’t even be able to handle half the current aircraft transmitting all at once. Bandwidth, in the physical sense, becomes a limiting factor Coverage (different constellations have different coverage, which means planes would not have transmit guarantees depending on flight path). So you’d have huge gaps anyways There have been alternative solutions posed, some of which are advancing forward. For example, GPS aware ELTs that only transmit below certain altitudes. But even that has flaws Anyways I think we’ll see it in the next decade or two, but don’t hold your breath
