Design and development

The P Bi4 was designed as a tandem glider for flight training and as such was referred to as the Bi4, indicating "bi-place" or two seater.

The aircraft's 15.20 m (49.9 ft) span wing has 58 cells, a wing area of 42 m2 (450 sq ft) and an aspect ratio of 5.5:1. The crew weight range is 140 to 225 kg (309 to 496 lb). The glider is DHV 1-2Bipl certified.

The wing design includes "Permanent Air Flow", a feature by which the cell openings are made smaller to improve the leading edge profile.
