It’s actually harder to do nothing and just watch things, it’s its own special kind of fatigue. I wouldn’t be surprised if this doesn’t happen more often.

For context, I was a private yacht chef for 7 years. On long legs of a trip I had to hold watch at the helm for 3 or 4 hour shifts while everyone else rested for their watch. Staying awake while using auto pilot was a special type of mental anguish.

First question - how do we tie this to Boeing? (A joke, of course) Second, interesting to note planes don’t have deadman switches.

> deadman switches Seems like they could address this by just changing procedures. If one pilot wants to take a nap, require a third crew member to come sit in the cockpit and make sure the other pilot doesn't doze off. When two pilots are awake, they can monitor each other, but if one is (intentionally) asleep, they can't do that, so have someone take over that function.

But you’ll need a fourth person to watch in case all three fall asleep.

Can someone explain to me why we still need pilots? Could we at least have pilots serve as a backup to a fully autonomous system?

This is such an “armchair expert” take on this. Planes are not fully autonomous. They will not be for a very long time due to the regulatory environment aviation is entrenched in.

Frankly it seems more like an "SWE take" more than a regular armchair take.

Earlier quoted context omitted.

That's not impossible, but the pilots' limbs are already largely "spoken for" by other controls and tasks, so it would be a harsh tradeoff.

If other controls are being actively engaged by the pilot, the need for the button press would be delayed only until there's some continuous period of non-engagement.

Exactly - something like positive activation every minute of some control or another or it starts hooting.

The two would have to fall asleep at the same time though. Otherwise, as soon as the SIC falls asleep, the third one would trigger some special protocol (like a kick in the tibia)

Unlike trains, there isn't one action that is basically always safe (stop the train). A dead man switch activating at the wrong time, could itself cause an accident.

That’s true, but there are plenty of other options. For example, a dead-man switch could: Send an alert via transponders that it has been activated. Maintain level flight but avoid terrain. (After a waiting period in which a pilot can deactivate this feature.) Or descend to a safe altitude if cabin pressure is lost. Activate a mode in which the plane could be remotely flown or directed to land itself. Alert flight cr…

There are fighter jets that will take over for an incapacitated pilot. I think it just goes to straight and level.

In addition to the other reasons - if someone is going to be qualified to fly the plane as backup, they need regular hours of practice. They could get that in a simulator perhaps, or flying practice flights, or ... by flying the actual plane.

I did delivers up and down the Atlantic in 2000s I remember it being awesome. Granted I was 20 and like the time we got too close to a us aircraft carrier and they launched a helicopter that did a fly over to check us out that was pretty great. We also always had lines out to catch fish and let me tell you when that line caught something didn’t matter if it was your shift or not it was “fish on” everyone jumping out of their bunks to help. Best fish tacos ever. I do remember the captain could be pass out drunk and still dock the 70 footer without issue and then stumble below to pass out. But yeah we slept a lot too but underway maybe 6-7 so plenty of time to fix or react big difference from an airplane or even autopilot car

One of the reasons the current "Self Driving" cars kinda suck. Majority of the time you're just not doing anything, but still have to be 100% attentive.

I've found the self-steering of new cars to be not at all useful for the stated use case. In my car, the self-steering pushes back a bit and deviates from the course ever so slightly so that you have to keep your hands on the wheel. I'd rather steer it myself.

But in those moments where I'm trying to find the UI for adjusting some climate setting, and I don't have my eyes on the road, that's when the self-driving is useful.

Maybe technology creates its own problems. To be fair, the radar cruise control is nice for long drives.

i can beat this. my dad was an RAF Vulcan captain and he and his entire crew fell asleep overflying Indonesia going from Australia to UK (they had being delivering to Australia a rocket component in the Vulcan's capacious bomb bay). the flight over Indonesia was completely illegal, but the crew figured that the Indonesian radars could not track the Vulcan (early stealth) and their fighters could not intercept it.

anyway, everyone woke up (reason for sleep never identified, afaik - i suspect hangovers)

this would be mid-60s.
