Ultralekki/Ultralight Register - SP-Z........ sequence

The Polish Ultralight ( Ultralekkie ) register covers a wide range of different types of aircraft - light aircraft/light gliders/ paramotors/ UAVs/gyrocopters etc

A further sub-section is Ultralight aircraft manufacturers test registrations - manufacturers may use these to do initial flight tests prior to customer delivery or perhaps if testing a modification - these are allocated in the "SP-ZABC" range

An example of the these test marks is SP-ZABL shown here on a gyrocopter prior to customer delivery ( in Poland gyrocopters are registered in the UL SP-XABC sequence )
