Artificial Horizon

In the early, perilous days of aviation, a pilots survival depended entirely on visual contact with the ground. The moment a plane entered dense fog or total darkness, human physiology betrayed the pilot; the inner ear could not distinguish between banking, climbing, or falling, leading to the deadly phenomenon known as spatial disorientation.
The invisible barrier to the golden age of flight was not engine power or aerodynamics, but the frail human sensory system. To conquer the skies, engineers had to invent an infallible, mechanical substitute for human perception. The solution was an ancient childrens toy—the spinning top—transformed into one of the most vital instruments in history.
This book traces the gripping history of the artificial horizon and the gyroscopic revolution. You will follow the obsessive inventors, like Elmer Sperry, who harnessed the rigid physics of spinning rotors to create a constant reference point, allowing pilots to fly blind through the most treacherous conditions without losing their sense of up and down.
Discover the mechanical heartbeat of modern aviation. By understanding the genius behind the gyroscope, you will appreciate how a simple spinning wheel conquered the chaos of the clouds.
