General information on the Be-103 amphibian
- The Be-103 amphibious airplane is an aircraft of normal category and intended for passengers and cargo transportation to the areas that are hardly to be reached by other transport systems -with a number of water areas. The airplane is able to perform the VFR flights day & night.
- The Be-103 amphibian is a low-wing monoplane, monoplane with a draught wing provided with a root rib extension, with all-moving horizontal tail and tricycle landing gear with nose wheel. There are fixed slats arranged on the leading edge of the wings at the area of the ailerons. Implementation of the concept with draught wing providing capability of aquaplaning on three points (step, LH and RH wings trailing edges) gives a considerable advantages in stability on water and seaworthiness.
- The airplane is equipped with two TCM IO-360ES4 piston engines, certified by FAA, Type Certificate E1CE. The engines with power of 210 h.p. each are installed on the pylons from both sides of the fuselage aft and above rear part of the wing center section. Such a configuration prevents water strikes to propellers while taking off and landing on water.
- Airframe design, layout, equipment and systems installed on the airplane meet the requirements of Part 23 of Russian Aviation Regulations for the airplanes of normal category and the Be-103 Certification basis, that considers amphibian operation features.
