One must respect airline pilots for the amazing skill they have acquired. We all know how to drive a car and operate the steering wheel and pedals to maneuver a car at speed and sometimes within a few feet of other cars that are stationary or moving in the opposite direction. Some of us know how to sail boats using a tiller and a few ropes to tack upwind and come about with fickle wind gusts. But the airline pilot! To have acquired a mental model of how to operate multiple controls, some embodying a degree of automation, to regulate thrust, speed, attitude, altitude, and heading-all interacting in complex nonlinear ways in three dimensions of space plus time as governed by the physical constraints of aerodynamics and control — what is going on in the pilot's head?
