In 1931, American aviator Wiley Post flew his single-engine Lockheed Vega -- the "Winnie Mae" -- around the world in a record eight days, 15 hours and 51 minutes. Post had a navigator by the name of Harold Gatty to help him stay alert and fight fatigue on that historic flight. But when Post became the first person to fly solo around the world in 1933, he had to do everything without an extra pair of hands. The secret to his success, or at least one of his secrets, was a simple autopilot that steered the plane while he rested.
Today, autopilots are sophisticated systems that perform the same duties as a highly trained pilot. In fact, for some in-flight routines and procedures, autopilots are even better than a pair of human hands. They don't just make flights smoother -- they make them safer and more efficient.
