Can a Boeing 747 Airliner land itself on Autopilot?
without any assistance from the Pilot?
All 747s are equipped with autopilot having autoland capability -
The last ones I was flying were certificated for ILS Cat.llla -
But they were fully equipped (and capable) to do Cat.IIlb landings -
That is land the aircraft, operate brakes, and stay on runway centerline -
Then when stopped, you disconnect the autopilot, and taxi -
The pilot only has to operate reversers if he so wishes -
In case of an engine failure, he will elect to use a symmetrical pair -
why dont you have a seat?
no, autopilot is just like cruise control on a car.
its only meant to be used in clear airspace and high altitude
Yes, it has a MFD, GPS, and multiple flight management systems that will not only land it by itself but reverse the engines and taxi to within 50 feet of the parking ramp
An aircraft only lands itself on autopilot only if the aircraft is doing an ILS landing, in other words, an instrument landing but 1 to 5 minutes before touchdown you have to shut the autopilot off.
Now I'm here to show you the art of doing the ILS.
Slow down to 210KTS and extend the gear at 195 KIAS and flaps to at least 15 to 40 degrees down, it depends if the aircraft is descending a little fast, medium to full flaps are needed, if the aircraft is descending too fast then you need to lower the flaps more. That's an example of how I do it, it depends on the type of bird your flying.
1- Operate the aircraft's radio stack by tuning to the frequency of the runway, the frequency of the ILS runway is entered in the NAV1 section of the radio stack. After tuning to runway frequency, push the little NAV1 on the bottom section of the radio stack.
While flying an approach, always operate the throttles, because if you don't, you'll overspeed the plane and you'll damage it. "THRUST A BIT HIGH, MEDIUM, THAN LOW and repeat the process, you'll need to be real careful.
2- Enter the given runway heading on the Nav Course panel which displays the runway heading number, ATC gives you a runway heading of x degrees so you put the heading the runway is on.
3-Engage the "GPS switch" and the autopilot "Nav" switch, in the autopilot section until the plane intercepts the localizer beam.Once the plane's radio stack beeps then it means that it already intercepted the localizer and the glideslope.
4- After it intercepts the localizer from 10 miles then you have to shut down the autopilot "Nav", then engage the "APR" autopilot switch so the plane can land itself. Switch the NAV/GPS button to "Nav" on the switch located below the autopilot panel near the primary flight display screen.
APR->NAV for ILS landing, NAV->GPS when en-route to destination and when flying the approach.

>>>>MAKE SURE THE PLANE DOES NOT STALL! STALLS MESS UP YOUR FLIGHT, TRUST ME, YOU WONT FEEL LIKE YOUR A SKILLED PERSON AFTER YOUR PLANE STALLS!
5. Manipulate the aircraft's pitch using the yoke and for flaring for landing, stabilize the aircraft's elevator by trimming the aircraft's pitch only trim the elevators very little or else it will result in a tailstrike and a bounce along with a botched up landing. REDUCE THRUST ON FINALS.
Most modern airliners are capable of landing automatically if the pilots so desire. This type of landing, called an autoland, must be set up by the pilots, but proceeds automatically once engaged, right down to applying the brakes and stopping the aircraft on the runway. Autolands are used when visibility is too poor for the pilots to see the runway clearly from far enough away to permit landing by hand.
So the airliner (be it a Boeing 747 or some other model) more or less lands itself, but the pilots do have to do a few things to set it up, such as selecting runways and tuning radios, engaging the autopilot, and so on. Autolands will land the plane automatically, but they are still designed to be used under the direct supervision of the pilots, who watch the autoland progress to make sure that all is going well.
