Paragraph 18 Flight crew and remote pilots

An MFC of a launch vehicle other than a balloon must be able to demonstrate an ability to perform tasks, equivalent in complexity to those which would be performed in flight, while exposed to the mental and physical stresses of rapid acceleration.

Whether the MFC satisfies the criteria in sub-paragraph (1) must be tested in a centrifuge device or an aircraft, or in a combination of the two, that is able to replicate the effects on the human body of the forces of acceleration, the rate of change of those forces and their duration, in conditions equivalent to the periods of the flight when those forces are most acute.
