Yak 52, like most Soviet military aircraft, was designed to operate in rugged environments with minimal maintenance. One of its key features, and a radical departure from most western aircraft, is its extensive pneumatic system. Engine starting, landing gear, flaps, braking and steering are all pneumatically actuated.

  1. See my comments re Miles Marathon, I guess no U.K. C. of A. for this one.
    Advantages of pneumatic systems : light. Simple.
    Disadvantages: leaks are hard to detect, and there is only one source of suck and blow, the engine. I guess there ought to be a row of back up air bottles, or else an engine failure would be verry interestink. The Chinese ripped this one off, as well, it’s called the Ying Yang Yong or something like that.
    Velly cheap on secondhand market, lots in OZ.
