G-tolerance limits

the maximum gravitation effects (g-forces) that an individual can withstand before blacking out as a result of acceleration drawing blood out of the head toward the feet (the +Gz direction). Pilots of high-performance aircraft can tolerate +9 Gz with use of G-suits and straining maneuvers. The duration of G-exposure and the type of safety protection used are important in determining whether or not blackout will occur.

constant error

a systematic error in some particular direction. Constant error is computed as the average positive or negative difference between the observed and actual values along a dimension of interest. For example, if a weight of 1 kg is judged on average to be 1.5 kg, and a weight of 2 kg is judged to be 2.5 kg, the constant error is 500 g. See also absolute error; random error.
