To Phlosphr:
What I’m saying is that by saying that, the ATC folks will know that YOU know what you are talking about, and you have just made their job about a thousand times easier.
Talking someone through using an autopilot is fairly easy…talking someone through a hand-flown landing is nearly impossible. By telling them that you know what you need to do, you eliminate the entire “convince me about this” discussion that would normally ensue when a passenger ended up in the front.
Imagine ten minutes wasted on “But that doesn’t make sense. Are you SURE the airplane can do that? Maybe I should just find a different person to sit up here…”
During those ten minutes the airplane is flying away from the airport and descending. If you say “set me up for an autoland” the controllers know that they are dealing with someone who knows the capabilities of the airplane, and they can focus on getting you down safely rather than convincing you that it’s possible to have the airplane get you down safely.
AFAIK this has never happened with a commercial airliner. The whole FAA medical checkup thing seems to be doing a good job of preventing both pilots from keeling over at once!
Upon preview:
crozell, good question and no offense taken!
The reason that I’m still needed is that flying is a very dynamic environment. Things change constantly. The flight plan that I load into my airplane on departure has about a 20% chance of surviving intact to the destination.
Decisions are made from the very beginning. Should we put on extra gas because of the weather en route? The flight attendants are complaining about someone who appears drunk. Do we boot them? (Yes). On takeoff, how close are those thunderstorms? Should we takeoff now or wait until they blow through? While cruising, which way should we deviate around that weather? Should we request a higher/lower altitude for a smoother ride? On arrival, our destination airport is socked in with a ton of airplanes in holding waiting to get in. How long do we wait before we divert? Can we change our divert airport to give us some extra holding time? On approach, when do the winds get too squirrely? When does the spacing just look wrong between us and the guy in front of us?
These are all decisions made on every flight. Now throw in something unexpected - a passenger has a heart attack in flight. Where do we go? How long will it take to get there? I sure don’t want my mother to be on a flight where the divert field was calcluated by revenue $/grid W minus computer fudge factor Q3. Add mechanical malfunctions (engine fires, loss of hydraulics like on UAL 232) and you quickly get away from what a machine can handle.
If you’ll notice in my first post in this thread, I said that the passenger + autopilot was a good way to survive, BUT if you had some sort of problem with the airplane then you were in trouble.
If you have any sort of weather problem you would be in trouble also. Place a raging thunderstorm over your destination, and watch the ATC folks scramble to find you a new place to land. Again, a human is involved and making decisions.
You can tell the airplane where to go, but it doesn’t know that going there involves flying through a thunderstorm, windshear or icing. It can tell you this when it encounters it (ie “Windshear!, Windshear!”) but it cannot AVOID it like you can.
This brings up the old flying adage: A superior pilot uses his superior judgment to avoid using his superior skills. In other words: stay out of trouble!
When I talked about Joe Passenger getting up front and hooking up the autopilot to save the day, I was assuming that everything worked as advertised. No bad weather, no bad aircraft systems, etc. Just a clear blue sky and a perfect aircraft.
I admit, on beautiful days with clear skies and not a lot of other traffic I feel like I am overpaid. But on a nasty night takeoff out of La Guardia with blowing snow, low ceilings, scratchy radios and turbulence up to 20,000 feet I think I am grossly underpaid. It all evens out, I guess.
