Speel´s WPR is a pocket-sized solid-state wireless recorder which is intended for recording flight data transmitted by its counterpart, the WPR´s transmitted unit (WPR-T) connected to a flight data acquisition unit (FDAU) onboard an aircraft.

The WPR pocket recorder is useful for retrieving flight data quickly (no need for data downloading at the aircraft) and for post-crash data recovery when the pilots ejects (with the WPR-R in his/her pocket) into sea, thus increasing the likehood of crash data retrieval and analysis.
