Mach Tuck
Definition
A nose-down pitching tendency that occurs when shock waves on the wing move the center of pressure aft as an aircraft exceeds its critical Mach number. Mach trim compensators automatically correct for this effect.
Why Mach Tuck Matters for Pilots
Understanding Mach Tuck is critical for passing the FAA Private Pilot Knowledge Test and performing safely in flight. Aerodynamics questions make up a significant portion of both written exams and oral checkrides. Pilots who grasp concepts like Mach Tuck can make better decisions during all phases of flight, from takeoff to landing.
Exam Tip
This concept is commonly tested in aerodynamics-related questions on FAA and EASA exams. Make sure you can explain Mach Tuck in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
