Winged vehicle profiles. Run 1 was designed to simulate winged vehicle suborbital spaceflight where passengers would be seated upright during launch and supine during re-entry, with sequential +Gz/+Gx exposures on ascent and +Gx exposure on descent (max +3.8 Gz, +6.0 Gx). Run 4 was designed to simulate a winged vehicle suborbital spaceflight with an occupant seated upright for both launch and re-entry, resulting in combined simultaneous +Gx/+Gz during descent (max +4.0 Gz, +4.5 Gx, 6.1 G resultant).
Capsule vehicle profiles. Run 2 was designed to simulate a nominal capsule launch with supine subjects. Maximum acceleration exposure was +3.2 Gx, with onset rates <1.5 G · s−1. No +Gz acceleration was experienced in this profile. Run 3 was designed to simulate a nominal capsule reentry, descent, and landing, with subjects supine in an orbiting capsule that decelerates during descent, followed by deployment of drogue and main parachutes, and finally, splashdown for a water landing. Maximum acceleration was +4.2 Gx with onset <0.5 G · s−1 in the +Gx direction, and total exposure sustained for approximately 4.5 min.
