B\u00fccker B\u00fc-131 Jungmann – Aviation History of Switzerland<\/a><\/p>\n\n\n\n

The B\u00fccker B\u00fc 131 Jungmann, a light biplane designed in the 1930s, was used as a basic military trainer in several European countries until 1957, then transitioned to the public sector as a specialized aerobatic aircraft with a more powerful engine. It is still in service at a few aviation clubs in Switzerland.<\/p>\n\n\n\n

It was introduced into the Swiss Army in 1935; 6 aircrafts were bought in Germany, 84 units were built under license by the Dornier company in Altenrhein, registered as A-7 through A-84. (The registrations A-85 through A-94 were requisitioned from the Aero-Clubs in 1942). It was on this aircraft that all generations of Swiss military pilots were trained until 1959.<\/p>\n\n\n\n

Training took place primarily at the Locarno-Magadino LSZL airfield, which at the time was equipped with three parallel grass runways. Basic training lasted six weeks, and after a rigorous selection process, student pilots continued their training on the P-2 and AT-16, as well as the Morane D-3801, before transitioning to jet aircraft.<\/p>\n\n\n\n

The aircraft\u2019s lightness and agility, combined with its open cockpit, provided pilots with an ideal environment for mastering all phases of flight, including aerobatics, and also allowed for the proper selection of pilots for fighter aircraft training.<\/p>\n\n\n\n

The original B\u00fccker B\u00fc-131 had only a limited electrical system (no battery, just a generator) and no hydraulic system:<\/p>\n\n\n\n

Starting procedure<\/strong> according to the original manual: \u201cPropeller: turn it by hand 5 to 6 times forward and, at the same time, simultaneously operate the fuel injection pump 2 to 4 times, set the magnetos to M1+2, operate the starter crank until the engine runs (generally, the engine was started directly by the propeller).\u201d The starter crank is not modeled.<\/p>\n\n\n\n

On the modeled version, a battery and a starter<\/strong> are available for starting the engine.<\/p>\n\n\n\n

The absence of a hydraulic system and electrical wiring made it impossible to install an autopilot.<\/strong><\/p>\n\n\n\n

There was no radio or transponder<\/strong>.<\/p>\n\n\n\n

A generator powered equipment for night flight: see manual, page 7.<\/p>\n\n\n\n
