What is a Mach Trim?

Mach Trim is an automatic control system used in some high-speed aircraft to adjust its trim, particularly as it approaches and exceeds the speed of sound. This system compensates for the aerodynamic changes that occur at high Mach numbers.

Functionality and Purpose: As an aircraft nears the speed of sound, it experiences aerodynamic shifts that can affect its stability and control. The Mach trim system automatically adjusts the trim to maintain stability and control effectiveness.

Critical in Supersonic Flight: This system is especially important in supersonic aircraft, where the effects of transonic and supersonic flight can significantly impact the aircraft’s pitch attitude and overall handling.

Integration with Flight Controls: The Mach trim system is typically integrated with the aircraft's flight control systems and is designed to operate seamlessly, often without direct pilot intervention.

Mach Trim is an advanced automatic control system in high-speed aircraft that adjusts the trim to counteract the aerodynamic effects encountered near and beyond the speed of sound, ensuring stable and controlled flight in these regimes.
