Mach trim operates
- along the longitudinal axis.
- along the lateral axis.
- to reduce Dutch roll.
Explanation
Mach trim addresses the nose-down pitch change (tuck-under) caused by the aft movement of the centre of pressure at high Mach number, working in the fore-and-aft (longitudinal) sense. It is a pitch/longitudinal function and is unrelated to lateral control or Dutch roll, which are directional/lateral matters.
