If it was that easy, you would be flying for Delta. “All” is a lot more than you imagine. You talk as if flying is as easy as using an elevator. What speed would you fly on final? What configuration of flaps? AND, only a few of the airplane types are capable of autolanding. Not all ILS systems are autoland certified. Enuff?
As an avid flightsimmer for many years I can answer all of those questions quite easily. All aircraft have a “kneeboard” for the pilots reference with all pertinent flight speeds for takeoff, cruising, landing, flap configs and speeds etc. Flight simmers such as myself know quite a bit more than you'd think about aircraft and flight controls and systems.
All Delta airliners currently in use have ILS landing systems and that's all they needed. Also, I'm sure the copilot could have landed the plane by stick if he had to. He has all the training necessary for just such an occasion in case the flight capt becomes incapacitated for any reason.
Your reply to me came off as really quite rude.
