Inside The Cockpit - Bücker Bü-131 'Jungmann'

Video from the channel Military Aviation History about Bücker Bü 131 Jungmann, linked on its Above Ten Thousand entry. Duration: 12:25. Language: English. Video type: Onboard.

The presenter visits a Bücker Bü 131 Jungmann in Lausanne (Switzerland) that Empa keeps airworthy. After a historical introduction, he sits in the instructor's rear seat and explains the cockpit and start-up procedure.

The student sat in front with only an airspeed indicator, altimeter and turn indicator, to focus on learning to fly. The instructor, behind, also had a compass, variometer, clock, fuel pressure, rpm, magnetos and primer. The elevator trim is on the right; throttle and mixture on the left, next to a lever to lock the tailwheel. The fuselage is fabric-covered steel tube and the wings are wood and fabric, interchangeable between the upper and lower position. To start, an assistant turns the propeller several times while the fuel is opened, a rich mixture is set and the engine is primed; then the ignition is switched on and the propeller is swung.

Bücker Flugzeugbau was founded in 1932 near Johannisthal (Berlin). The Bü 131 flew in April 1934 with an 80 hp Hirth, and the B version moved to the 105 hp Hirth HM 504, in production from 1936. It was exported and built under licence in Switzerland, Spain, Hungary and Japan, which built about 1,400. German production fell somewhat short of 2,000. It is 6.6 m long with a 7.4 m wingspan, reached about 182 km/h and had a range of 650 km. Withdrawn from schools, it moved on to liaison duties and night harassment attacks.
