I have a pretty good Simulator setup at home, with the majority of real-world external (from the computer) controls, pedals, instrumentation, Nav etc. etc. And I use them all properly, to simulate real flights. However, even 'I' would admit that to be 'thrown' into the pilot seat of a real Passenger Jet would be overwhelming!! Sure, I would do better than someone who knows nothing, having extensive knowledge of speeds, flaps, stall speeds, decent rates/instruments, landing gear, nose pitch attitude, how to go around etc., but the COMMs/NAV instruments would be lost on me in the 'moment'. I'd rather do it myself, than my Missus who still can't reverse park after 40 years!!
