C-9B Flight Trajectory

The above diagram shows a typical zero-g maneuver. However, the maneuver can be modified to provide any level of g-force less than one g. Some typical g-levels used on different tests and the corresponding time for each maneuver are as follows:
* Negative-g: (-0.1 g): Approximately 15 seconds
* Zero-g: Approximately 25 seconds
* Lunar-g: (one-sixth g): Approximately 40 seconds
* Martian-g: (one-third g): Approximately 30 seconds
