SPRINGDALE -- Millionaire adventurer Steve Fossett became the first person to fly solo around the world without stopping or refueling, but he did have some help in the cockpit.
An autopilot designed and built by TruTrak Flight Systems of Springdale shared control of the GlobalFlyer with Fossett.
TruTrak General Manager Andrew Barker said he learned the autopilot was turned on three minutes after the plane took off. The autopilot was turned off 12 minutes before landing after the 67-hour flight. Barker and company co-founder Chuck Bilbe attended the landing in Salina, Kan.
Company co-founder Jim Younkin monitored flight data on the GlobalFlyer Web site and watched the landing from the company facility at the Springdale airport.
"There is no way a human pilot could fly a plane with that much precision," Younkin said. "It has to be the autopilot. "
Younkin and Bilbe designed the one-of-a-kind autopilot after they were approached by Fossett's group in 2002.
"They had talked to a company which designed for the military, but the company wanted half a million dollars," Younkin said. "I thought we could do it for less than that. "
TruTrak makes autopilots and other aircraft instruments for the experimental aircraft market.
The autopilot system, which included backups for the computer and the servo motors, was designed to control a plane even as the aircraft loses about 80 percent of its loaded weight while in flight. The weight loss come from the fuel burned during flight.
"We had to come up with a servo which was strong enough to handle the forces in the fully loaded plane," Younkin said. "Nobody had one that could handle that. "
The system also had to be responsive enough to guide the plane during a climb to 50,000 feet, which could take 10 hours. Younkin said most autopilots are designed to work at 25,000 feet, where response is much better due to the thicker atmosphere.
When finished, the autopilot could handle everything except takeoff and landing, Younkin said.
The TruTrak staff gathered to watch the airplane complete its historical flight.
"They are making a big deal about the landing," Younkin said. "The landing is nothing compared to the treacherous takeoff with the plane fully loaded. "
Fossett, whom Younkin said was a very good pilot, handled the touchdown to complete the historic flight.
"That was something I wanted to do for a long time, a major ambition," a jubilant Fossett said immediately after emerging from the custom-built GlobalFlyer.
An equally happy Sir Richard Branson, the Virgin Atlantic founder who financed the flight, grabbed a bottle of champagne from Fossett, shook it up, and sprayed down his pilot and longtime friend. Fossett then guzzled from the bottle in celebration.
Fossett, 60, already holds the record for flying solo around the globe in a balloon. He failed five times before successfully completing that flight, but needed just one try to make the trip in a plane.
There was some doubt Fossett would make it back to Salina. Fuel sensors in the custom-built plane's 13 tanks differed from readings of how quickly its single jet engine was burning fuel, forcing Fossett's crew to assume that 2,600 of the original 18,100 pounds of fuel "disappeared. "
It was not clear whether there was an actual leak or just a problem with the sensors, Fossett's team said.
Facing a decision near Hawaii about whether to land or press ahead over the vast Pacific Ocean for the U. S. mainland, Fossett told his team, "Let's go for it. " Hours later, pushed by strong tail winds that left him with enough in the tanks to finish the global trek, he safely crossed over Los Angeles and turned northeast for Salina, touching down there at 1:48 p. m.
