| Source measurement | — | According to aviation journalist and ex-IAI engineer Danny Shalom, substantial work on the development of what would become the Arava commenced right after the Six-Day War between Israel and several neighbouring nations. Prior to this point, Israel Aerospace Industries (IAI) had largely confined its aircraft manufacturing efforts to producing copies of existing French and American designs, such as the IAI Nesher . However, many of the company's engineers were keen to develop beyond imitation and reverse engineering effort, for IAI and Israel to produce its own unique and indigenously produced aircraft. Around this time, the company foresaw a requirement for a new generation of transport aircraft that would suit operations from runways only 400 meters in length. IAI had forecast the international market demand for such an aircraft to be massive and that, by obtaining only a 20% market share, the company would sell between 400 and 600 aircraft throughout the life of the programme.[source]IAI Arava · Design and development / Origins; only the objects and conditions stated in this passage As the design took shape, key performance objectives included Short-Takeoff and Landing (STOL) capability, the ability to operate the type from unprepared/rough airstrips, as well as the carriage of up to 20 passengers or bulky payloads. The Arava featured a barrel -like fuselage , being relatively short but wide, while the rear of the fuselage was hinged and could swing open for easy and rapid loading and unloading. Its wingspan was long and the twin tails were mounted on booms that ran from the engine nacelles . It was fitted with a fixed nosewheel undercarriage to save weight, while the chosen powerplant was a pair of 715 eshp (533 kW) Pratt & Whitney Canada PT6 A-27 turboprop engines. The design configuration bore considerable similarity to the French Nord Noratlas transport plane, which was already being used at that time by the Israeli Air Force (IAF).[source]IAI Arava · Design and development / Origins; only the objects and conditions stated in this passage Civil passenger aircraft for up to 20 people in airline-standard configuration or up to 12 passengers in VIP configuration[source]IAI Arava · Variants; only the objects and conditions stated in this passage The military version could also be equipped with a range of weapons, in order to act in anti-submarine- or gunship roles. The weapon configuration could include two machine guns in fuselage side packs (usually 0.5" Browning), plus a third gun on the rear fuselage, and two pods containing 6 x 82 mm rocket pods or torpedoes or sonar buoys on the fuselage sides.[source]IAI Arava · Variants; only the objects and conditions stated in this passage Bolivian Air Force – Six purchased 1975–76.
