Does parabolic flight cause undo stress on the aircraft?
No. G-load stress on the 727 during parabolic flights ranges from 0 G’s to +1.8 G’s. The Boeing 727-200 was originally certified by Boeing to stresses ranging from -1 G to +2.5G. ZERO-G’s operations are well within Boeing’s original specifications. In addition, ZERO-G has implemented a maintenance inspection program based on a detailed structural analysis.
