Raymond J. Hilton, 65, who helped usher in the computer and satellite age of air traffic control, first as a researcher with the Federal Aviation Administration and then as an official with the Air Transport Association of America, died of lung cancer Dec. 9 at Holy Cross Hospital.

Mr. Hilton, who began his career as an air traffic controller in Pittsburgh, worked for the FAA from 1957 to 1981.

By the mid-1960s, Mr. Hilton was working at the FAA experimental research center in Atlantic City and as part of a team that created the early computer hardware and software for air traffic radar systems.

He joined the Air Transport Association soon after his retirement from the FAA in 1981 and represented airlines primarily in air traffic control issues. He also was involved in the development of flight patterns for transoceanic travel.

A Silver Spring resident, he was a native of Pittsburgh. He attended what is now Slippery Rock University of Pennsylvania and Rutgers University before serving four years in the Air Force as an air traffic controller.

He was a member of St. John the Baptist Church in Silver Spring.

Survivors include his wife, Frances Hilton, of Silver Spring; two daughters, Kathleen Hilton of Dillon, Colo., and Laura Krick of Lewes, Del.; and two granddaughters.
