A Polish Commercial Aeroplane: The P.Z.L. Wicher, a Monoplane Designed and Built on Modern Lines Available to Purchase

THE National Aircraft Establishment has in the past produced numerous interesting and novel aeroplanes (one of these, the P.Z.L.37, was described in AIRCRAFT ENGINEERING, July, 1938) and their entry into the field of air transport is an event of importance. The machine is intended to replace the American Douglas and Lockheed aeroplanes now in use on the Polish Air Line, “Lot.” Although it is built on fairly conventional principles and is not specially fast, it is of very robust construction and is probably the fore‐runner of more interesting designs to come. The constructors claim that in considering this design they treated general safety as the main desideratum.
