The Horizon and Diplomate are moderately elite retractable undercarriage four seaters which were implicit generally unassuming numbers.
The introductory GY-80 Horizon started life as a secretly created outline penned by Yves Gardan, who had likewise been in charge of various other post bellum light flying machine plans. Gardan manufactured a model as a private advancement which flew on July 21 1960. After two years, Sud Aviation (now Aerospatiale) gained the configuration and generation rights for the GY-80 and put the sort into creation. Sud Aviation assembled three preproduction improvement airplane before putting the GY-80 into creation in late 1963.
A key perspective to the GY-80 was its basic configuration and technique for development. The GY-80 was of traditional appearance yet marginally uncommon development, with an aluminum cleaned steel tubular structure for the lodge range, and monocoque tailcone blasted rearward. It offered a retractable tricycle undercarriage, Frise opened ailerons and Fowler folds. The folds are forever joined with the undercarriage linkage which is wound all over physically with a handle distending from the instrument board. To diminish upkeep costs, the folds, ailerons and flat tail pieces were exchangeable (in principle, yet they required to be altered on the off chance that they were awhile ago utilized at another position). The Horizon was manufactured utilizing auto get together procedures, with only 11 creation dances.
Three renditions of the Horizon were constructed, contrasting in powerplant and fuel tankage. These were the 110kw (150hp) Lycoming O-320-A controlled GY-80-150, the 120kw (160hp) O-320-B2b fueled GY-80-160, and the 135kw (180hp) Lycoming O-360-A fueled GY-80-180. These were fabricated firstly by Sud Aviation, and after that by its recently settled light airplane division, Socata, from 1966.
Socata flew an enhanced improvement of the GY-80, at first called the Super Horizon 200, on November 7 1967. This new advancement emphasized an extended lodge and an all the more compelling 150kw (200hp) fuel infused Lycoming IO-360-C. In generation somewhere around 1969 and 1974, the Super Horizon was renamed Provence, and afterward the ST-10 Diplomate, the recent turning into the sort's authoritative name.
