In 1960 the GY 80 Horizon 180hp tourer appeared. This single engined machine won the Cannes International Grand Prix in 1966, beating the highest performance twins of the time by covering in 23 h of flight a distance of 3443 mile at 152 mph average (5540 km at 245 kph).
The Horizon had a run of 270 in France, Aerospatiale having ac¬quired the production licence, but its succes¬sor the GY 100 in 1969 was never produced commercially.
One of SOCATA’s first products was the four-seat GY.80 Horizon under licence. The type first flew in July 1960 and is of all-metal construction with standard low-wing monoplane configuration and full span Fowler-type flaps and Frise-type ailerons. All three tricycle landing gear units retract to the rear and leave their wheels partially exposed.
The GY-80 was built in four basic versions. Standard versions have 160 hp or 180 hp engine and fixed pitch propeller. A constant speed propeller was available optionally with either engine.
The first 75 aircraft have the 119-kW (160 hp) O-320-D engine driving a fixed-pitch two-blade wooden propeller, later aircraft having more power and a constant speed three-blade propeller.
Production of 260 aircraft last to 1969.
