It has a twin turbo-prop powered non-pressurised shoulder-wing monoplane with rectangular-section fuselage and a double passenger/cargo door. The aircraft is used in the fields of optical remote sensing, oceanography, atmospheric and earth science research. A range of sensors may be installed.\r\n\r\nDimensions:\r\n\r\n      Length: 15.04 m; Height: 4.86 m; Wingspan: 16.87 m; \r\n\r\n\r\nFlying performances:\r\n\r\n      Speed:\r\n            Min speed: 62 m/s\r\n            Max speed: 83 m/s\r\n            Usual speed during measurements: 65 m/s\r\n            Usual speed during transit flights: 98 m/s\r\n            Ascent rate: 1000 m/s\r\n\r\n      Altitude:\r\n      (1 ft = 0.31 m)\r\n            Min altitude:\r\n                  Above sea: 200 ft\r\n                  Above ground: 500 ft\r\n            Max ceiling: 22000 ft\r\n            Usual ceiling during measurements: 15000 ft\r\n            Ceiling limitations:\r\n                  The service ceiling for our normal operational science is 15 000ft.
