Asking because of Air India 171. Pilots and their unions are objecting to it because of "privacy" reasons. What do you think about it?

No, because flight recorders already save large amounts of information about what the plane is doing, the pilot inputs, and what is being said audibly. I'd like to understand how a visual that vastly increases the storage requirements would help understand an event.

[–] sanguinepar@lemmy.world 20 points 2 days ago (1 children)

Agree with your overall point, but in this Air India case a visual definitely would help to see which pilot (if any) flicked those switches to off. The audio is ambiguous.

[–] ryannathans@aussie.zone 9 points 2 days ago (2 children)

Wouldn't the state of the switches be logged on the flight recorder?

[–] NaibofTabr 31 points 2 days ago (1 children)

Yes, but it might be very important to determine: did the pilot/copilot flick the switch, or did the switch change state without user input?

Is the crew at fault (training issue/operator error) or is the manufacturer at fault (design flaw) or was the ground crew at fault (improper maintenance)?

A camera could help determine that, if it had the right field of view.

Mechanical switches aren't flipping themselves 4 seconds apart

[–] 4am@lemmy.zip 9 points 2 days ago

No, but a short circuit might

[–] TheWeirdestCunt@lemmy.today 7 points 2 days ago

it is, mentour pilot released a video about the preliminary report the other day where it's mentioned that the fuel pumps were set back to active with a 4 second delay between flipping each switch.

this link should be set to the time stamp where he goes over what happened with the switches: https://youtu.be/lVS76zcpZok?t=1102

vastly increases the storage requirements

A couple terabytes of SSDs is a trivial expense on a commercial aircraft in 2025.

[–] IphtashuFitz@lemmy.world 6 points 2 days ago (2 children)

You wouldn’t want this video stored on traditional SSDs though. You want it stored on media in a black box like the voice & data recorders so that it can survive crashes, fires, etc. Not sure what the costs associated with that would be though…

[–] Zak@lemmy.world 2 points 2 days ago

I'll leave the implementation details to the experts, but I'm sure there is a suitable option for storing 24 hours of video that adds only a negligible amount to the cost of a quarter-billion dollar airplane like the 787.

[–] madcaesar@lemmy.world 0 points 2 days ago

Again, negligible

A couple terabytes of SSDs is a trivial expense on a commercial aircraft in 2025.

I hear a similar argument daily -- that the consumer no-RAID stuff is so cheap and thus storage should be cheap. The stuff you get on the shelf isn't valuable here as it wouldn't survive a crash. The consumer stuff would die quickly just from the brutal power-blips the system undergoes just as part of regular flight operations and power-source switching.

[–] Zak@lemmy.world 1 points 2 days ago

It could cost a hundred times as much and we're still only in the fifth digit of the airplane's nine-digit price tag.

[–] masterspace@lemmy.ca 3 points 2 days ago

I think you're probably vastly overestimating how much increasing the storage on a flight recorder would cost.

Even magnetic storage has vastly dropped in price over the years, it's just become less common.

[–] venusaur@lemmy.world 4 points 2 days ago

The concern here is storage requirements?

Having no visual is a huge disadvantage. You miss a great deal of context.
