That's easy. They take up space, the two of them weigh as much as two more SLF, they need two more hotel rooms at the other end...

Re: Pilotless A/C

I noticed someone mentioned that we don't have driverless trains. The reason for this (and also why no public transport systems are driverless) is because the only way they would be safe is if you could factor out any human element. By human element this is referring not to pilots but the people who maintain (and produce) the aircraft, trains, buses etc. Engineers (like pilots) are human and will make mistakes. These instances require the ability of out of the box thinking from the operator of the vehicle, especially if mistakes are made in relation to the computer responsible controlling the vehicle. Only when maintenance becomes either fool proof or automated will unmanned transport have the possibility of being implemented on a major scale.

On a personal note with a pilotless flight deck the argument for could someone hack into the computers of all the planes flying over the US, for example, and cause mass devestation is a strong one. If the security agencies can't keep their systems 100% secure there is no hope for airliners.

With regard to having pilotless military aircraft. This I am completely against. I do not believe we should ever have automated military as this simply removes the cost of war.

However, the disscussion of will there be a pilot career, due to it being replaced by a computer is not the more immeadiate case. The question you should be asking is "will there be a pilot career, due to there not being any fuel to run the aircraft on?". This because oil will run out well within my lifetime whereas the chances of pilotless aircraft in my lifetime is pretty remote.

Re: Pilotless A/C

judging by some of the actions Ive seen, I thought we already had some pilotless aircraft!

Re: Pilotless A/C

in military aviation i'm certain that the unmanned aircrafts will be a very big part of the picture but in civil aviation there's no way

if people hesitate flying just because an aircraft has props instead of jet engines i doubt they will fly in an aircraft conveyed by computers

and if i recall it correctly there was a test with an unmanned A320 or something, the famous clip on the net where it decends after a touch and go and flies touching tree-tops before crashing

also what if someone decides to shut down the GPS system? what if the analogue instruments get malfunctioned and starts feeding bad data to the computer and things go bad, what if someone jams signals when the aircraft is on a short final? there are no pilots onboard to visually discern the real runway from the jammed frequency, radar altimeters can be jammed easily and barometers break

i don't see a future in unmanned civil aviation within a century

Re: Pilotless A/C

Anything relying on total "remote control" is definitely at risk, for the reasons Ozcan mentions.

But how about a scenario where - like the much quoted DLR - there's a "driver" on board, who only overrides if there's something serious amiss?

I'm sure if we can trust systems to fly right up to the flare, then there's enroute stuff that can be automated.

The counter argument, is, I guess, that having crew on board won't save money so why bother with all the expense of developing such a system. The only then, I can think of, is if it's safer?

(And now, with no supporting facts either way, I disappear in a puff of badly thought through hypothesis. )

Re: Pilotless A/C

Think really hard about the following list of parameters for real aviation, Heavy and Light. If you will understand how painful it is (in a non-MIL environment) to pay for testing, repair, and replacement of very expensive complex systems components, time and time and time again, then likely you will conclude that inexpensive, interchangeable and amazingly adaptable crew persons will be desirable in the process for a long while to come.

Re: Pilotless A/C

I agree, more and more automation will come, I don't see a scenario with no pilot at all on airliners. But certainly one will be able to do the job in the future. "Beancounter's heaven." only half the pilots to pay.

Re: Pilotless A/C

Problem with one-pilot vs five or ten thousand multiple-redundant onboard computer thingies is: "who wins the coin toss when flesh and silicon seriously disagree?".

At present, the toss favors the TWO guys/gals with the big watches.
With same rules, but only ONE person (i.e. no redundancy for the various failings to which the flesh is prone), most analyses would favor the (we're assuming they're "well-engineered and thought out", which may be the case 20 years from now) boxes.

Hmm just great.. in the Paper today they say that Pilots are not needed anymore , whats up with all the fuzz about pilots these days

Sorry folks, i'm an ATC type person and I'm just trying to get my head round this.....

After Take off, how much can the FMS do of your work anyway? Can the autopilot take you direct to destination and even land the damn thing if autoland equipped?

Well, take the example of the Helios Boeing 737. When the pilots were stupid enough to take off with outflow valves wide open, try to turn off the decompression warning instead of putting on oxygen masks and pass out as a consequence, the autopilot did what it was supposed to do if the pilots were playing cards etc. and not touching controls: it went on climbing to cruise level, flew to destination - and, when no one tried to land the plane, circled on its own around the last waypoint until it ran out of fuel.

Basically, I suppose that had pressurization worked, the autipilot would have done the same if the pilots, instead of fainting, would have got up, locked the empty cockpit and spent time in the cabin until reaching the hold pattern.

However, this is what actually was done by the autopilot of this (rather old) plane. What could an autopilot possibly be made to do?

[Bombay Bad Boy]

Re: Pilotless A/C

But what if the autopilot would have been configured to go further than just the holding facility. I know thats not the done thing but isn't it conceiveable that a crew could program the system so that as soon as the aircraft takes off, the plane will fly itself to destination and make an approach?

That sounds fairly achieveable to me, so surely there must be limitations to the systems?

"That sounds fairly achieveable to me, so surely there must be limitations to the systems?"

Yes. For example, the aircraft arrives in the holding pattern, sets up for an approach, and the runway is blocked. How do ATC manage the stack?

Or, there is an on-board medical emergency requiring the aircraft to divert immediately, or a fire, or a disruptive passenger endangering the aircraft from within the cabin.

In cases like these, who re-programmes the aircraft? ATC? Ops? The FA? Or the senior passenger?

Airlines need a pilot to blame. In the event of an accident, a pilot who has made a mistake can be given the blame, be fired, the airline announces it in the media, gets a new pilot and carries on. If there's no pilot in the new, much publicised, all singing, all dancing "Blunderbus" and suddenly there's an accident because something went wrong with the aircraft, what does the airline do? Sell the fleet?

[Bombay Bad Boy]

Shy Torque - I get your point, in fact I entirely agree with it! But your missing mine.

I was interested to know that if the crew configured the FMS on the ground, then after take-off, they pressed the autopilot would it fly to destination and land? What I meant by limitations was any selection of flap or landing gear issues?

Not in current aircraft. All gear/flap/slat selections are still entirely manual, not automatic. Also, an airplane flying in VNAV will climb to the pre-set altitude, but will not start a descent unless the pilot has manually entered a lower altitude in the mode control panel. Oh, and autobrakes need to be set manually. And thrust reverse is manual. And the approach mode needs to be selected manually. And the go-around altitude. And the speedbrakes need to be armed. And...

Of course one could automate all of that quite easily, but then we'll still not be able to have a pilotless passenger airplane, since take-off, weather avoidance (clouds, turbulence), TCAS manoeuvring (even controller-less ATC might not be able to avoid traffic conflicts, I guess), taxiing, and engine start-up need to be automated too. And at that stage we haven't even begun to consider the simplest of emergency scenario's.

No, I think I'll let someone more adventurous than me try that first automated flight.

[Bombay Bad Boy]

Xetro V..... Thank you for your reply, that is the sort of understanding I was trying to grasp! I'm sure that even the most cost-cutting technology-advanced company would find it hard to commision a pilotless aircraft in the commercial world. Even in ATC, boffins bark on about automating the whole system, but like in your situation what about emergencies? weather avoidance etc? I think its safe to say, Not in our life time!

Thanks again

Heh. I've printed this thread and will include it in a 'time capsule' being put in the footings of a new building my firm is doing work on. Estimated lifespan of the building is about 75 yrs, so it should make interesting reading (unless a UAV crashes and totals the structure in the meantime!)

[Bombay Bad Boy]

RJM - Ha ha very funny. Some of us are actually learning things from this thread! Aircraft/Pilot/UAV limitations etc There are similiar questions being addressed in the ATC world right now!
.

I have a further question:- If the FMS was programmed from the holding facility to make a an approach at an airfield, how would it cope with changing from FL to Alt on the altitimeter?

Pilotless aircraft?
There are a few steps along the way and we may see one or two before too long.
First is the ability to operate unmanned aircraft in controlled airspace, which is being worked quite hard. See-and-avoid and failure tolerance are the issues, but I would be surprised not to see this within five years.
Next, what if someone takes the brains and electric actuators out of a UAV and makes a RoboCirrus, a FBW private airplane? Might be appealing because it would be simple to fly, and electronics and electric power are getting steadily cheaper and mechanical controls are not. Cost of ownership might be competitive.
Now, add elements one and two and add a big red button on the panel, for use in the event of emergency - pilot incapacitation, mechanical problems or operational issues that have put the pilot out of his/her skill level. And an XM datalink so that there is a human on the ground supervising the recovery to nearest airport. OnStar for aircraft!
And maybe next this becomes an amber button, for contingencies - it's turned foggy at my destination but I really don't want to divert.
And at some point along the way, FedEx adopts an unmanned cargo aircraft to replace its Caravans.

[David_Lid Air]

Hmmm.. freighters with no pilots in only maybe 10yrs ahead sounds pretty soon to me, too soon.. Like Captain Pirate said i think it will take a long time before they replace pilots! Why the hurry? all aviation anthusiasts nightmare must be when there are only computers left. Or? private planes without need for a pilot? i dont see the benefit really, sounds very very expensive
