...in which case the autopilot senses a deviation from a set
safe course that was programmed in before the flight, and
steers the plane back on that course.
This same principal as those cars they have at amusement
parks that you drive along a guide rail that allows some
steering of the vehicle
until it hits the rail. The pilot would
be allowed the latitude fly above rough weather or make
minor deviations in course but only within a set
programmed
safe corridor that would not include mountains or
skyscrapers.
In case of crazy pilot syndrome, like the guy circling around
until the fuel runs out, the plane would go into "this guy's
nuts" mode and automatically land at the nearest airport.
This is more of a move towards autopilot controlled aircraft
with a pilot on board for emergencies since the pilots would
be flying the plane instead of just being on standby in case
something went wrong. The latter scenario would require
somebody who hasn't flown for hours, days or months to
suddenly take control of an aircraft in peril requiring the
greatest pilot skill possible, something you wouldn't' get
from somebody who doesn't actually do a lot of flying since
the autopilot usually does everything.
Takeoffs and landings could even be controlled by the pilot
with safety restrictions imposed by the automated flight
system I would think.
The incredibly competent guiding hand of technology
running the show but giving the bio just enough control to
keep in practice should the automated systems break down.
And the fun part would be that anybody could fly a 787
with absolutely no practice, although in reality you
wouldn't see this much. "Ladies and gentlemen, our pilot
today is Bobby who just turned 5 years old today. His little
sister will be handling the rudders since he can't reach
them just yet so hold on! Ok Bobby, push the "FLY NOW"
button."
I'd suggest the term "soft control" for this scenario where
the pilot controls the plane only within a set of parameters
controlled by the autopilot.

If you're going to create a system that can fly the plane, what do you need a human pilot for? More half measures. |
|

Autonomous flight or don't bother. |
|

If that idea is adopted, then why have pilots at all? Might
it be possible to get the human out of the cockpit
entirely? Drones can fly pre-programmed routes and can
even takeoff and land autonomously. Why not airliners?
DARPA is working on a new form of positioning system
that is 50 times more accurate (if it all works out) than
present day GPS and does not depend on satellites at all.
The system is self contained within the robotic system,
thus eliminating the need for any outside assistance.
They might keep a pilot or - perhaps the new term would
be On Board Digitial Manager or Assistant. Ground control
would supervise the flights, but the on board systems
would do all the actual control. |

In case the autopilot system breaks down the human
pilot can take over. |

You can't have that. The human pilot will crash the plane into the ground. |

We are at (or closely approaching) a decision point regarding automated computerized big moving machines. It's already been made in some sectors. The mining industry is using self-driving trucks to haul material. We're starting to hear of designs for subway/rapid transit and heavy rail that use automated trains. Unmanned cargo ship plans are well into the development phase. Google's self-driving cars and similar technology are poised for a breakthrough soon. Probably in our lifetime, freight trucking will be transformed with automated trucks running 24 hours a day on the highways. We'll all be calling Uber self-driving cabs. Within a few decades it would not surprise me to hear of highways that prohibit human drivers. |
|
| |
So this decision has to be made with regard to the airline passenger and cargo industry as well. Sooner rather than later. There's a lot of heavy lifting already done by drone programs to learn from. |
|
| |
We've been doing things ourselves for so long, we are resistant to this change that is certainly going to come one way or another. The technology is there, and ultimately, autonomous systems will do a far better job at these sorts of tasks than humans ever could. |

//You can't have that. The human pilot will crash

|
| |
The pilot is unable to crash the plane into the
ground unless for some reason the autopilot fails. |
|
| |
The chances of the autopilot breaking down and
then the pilot going nuts at the same time are very
low. |

tatter just fyi the f14 from the 80s and all fighter jet since
cannot be flown manually. So your question in any case is a
good one. |

Did you forget cyber crime? |

Mmmm. This doesn't have particularly good penetration yet, which you can read into all you like but basically means it's not working very well yet at the moment. Certainly 99+% of mining trucks, diggers, etc are manned or have operators a short distance away (ie remote underground mining equipment). The only real area in mining where equipment is now largely unmanned is that of stackers reclaimers and shiploaders. It's now the norm for them to be fully automatic, which 10-20 years ago was not the case. Even still, shiploaders loading low density material (where ship holds need to be filled to capacity, involving winnging out and trimming holds), or that maneuver over ships with furniture (ie derricks or vertical hatches such as handimax) will exclusively require manned operation, and will continue to do so for some time. |
|
| |
I'm just saying don't jump the gun on the whole unmanned vehicles thing yet. How does the google car respond to an accident with debris on the freeway, or a deer jumping out in front? Or any number of unpredictable, volatile situations? |
|
| |
I think the transition will be a long, slow and cautious one. But probably also an inevitable one. |
|
| |
There are still a lot of hurdles for the Google cars, no question. I didn't imply they are ready for prime time quite yet. |
|
| |
I think those issues will be solved sooner rather than later, however - many other companies are working on this stuff now than when it was just Google. Tesla's latest update will allow drivers to travel from SF to Seattle hands-free. Vehicle summoning and self-parking are coming later this year. |
|
| |
I suppose it concerns me because we're perfctly happy to accept human error as a cause of accidents, but computer error would be a big deal. |
|
| |
First time a google car or similar makes a bad move and causes a multi car pileup, shit's gonna hit the fan. Talk about a liability nightmare. |
|
| |
...Anyhow, in the context of the idea which is pilot-in-loop, these concerns are less relevant. Whether the pilot overrides a normally-on autopilot, or an ever-vigilant autopilot overrides in the event of pilot error, either way there's a degree of safety above what's currently in place. |
|
| |
But a determined person, especially one with access to a cockpit, will always be able to disrupt a flight if not crash it. |
|
| |
Agreed. Regardless of how hard you make the security and reliability for the autopilot, airplanes are still pressurized tin cans in air which there are a thousand ways to break. |
|
| |
There's also this thing called the weather. I'm not sure if an autopilot can manage its way through a storm yet. Drones don't really care if their passengers reach for the barf bags, because they have none. |
|
| |
// we're perfctly happy to accept human error as a cause of accidents, but computer error would be a big deal. |
|
| |
I think we should be concerned with both, obviously. But the difference is one can be fixed, the other can only be obstructed or contingency-planned. A hundred years into powered flight and here we are trying to find ways to prevent deliberate crashes. |

The idea of having a pilot fly continuously, albeit in a
restricted mode, is to have the human in top flying
shape at all times instead of getting waken up from a
6 hour sleep by an alarm system saying "You have 15
seconds to make the right decision because the
autopilot just died and we're about to hit a
mountain." |
|
| |
He will probably have had most of his practice in
simulators at best because
it's too expensive to have standby pilots train on real
planes that cost real money with a primarily
autopilot controlled fleet. |
|
| |
I respectfully submit that there's something to be
said for this idea. |
|

A pilot who has to fly the plane continuously will
probably make worse decisions due to fatigue.
Similarly, a pilot who has to watch over the autopilot
continuously will also suffer from fatigue. A human
can only perform a task alertly for something like 15
minutes without a break. Therefore, I think it would
be safer to let the autopilot handle the easy flying on
its own, and save the human pilot's attention and
stamina for the difficult stuff… which is pretty much
what they do already, though pilots are allowed to
take over at any time. With this corridor, I guess they
wouldn't be able to take over and fly outside of the
autopilot's bounds as long as the autopilot is
confident it's capable of handling the situation.
Obviously you want the human pilots to be able to
take over on a moment's notice in case the autopilot
fails, so you can't let them sleep, but you should let
them read or play games or something so they don't
get fatigued from flying continuously. |
|
| |
So what if the backup pilot hasn't actually flow a
plane for a couple of years? Where do they get their
training? Do you just buy a second training fleet? |
|
| |
Pilots have to have a certain number of recent flight
hours to be ready to fly. The only person who would
need more flight hours than a regular pilot would be
an emergency pilot. |

news for anybody going in for brain surgery. Or a tax
consultation for that matter. |
