Could you land an airliner in real life?

Question to the hardcore close-to study level flight simmers out there.

I know its an age old cliché that the pilot of a flight you are on has a heart attack and someone needs to flight the plane, this is of course a situation that will never happen and we will never find ourselves at the helm of an actual plane and be expected to fly it.

But hypothetically, if this did happen how many of you would feel confident that you could fly the plane and actually bring it down to a safe stop?
