What is the Maximum Mach number of the 737?

• A. .88 Mach
• B. .82 Mach
• C. .78 Mach
• D. .90 Mach

Answer: (B)

Max Mach number is the highest speed at which the aircraft is certified to operate in flight. It reflects the aerodynamic stability, control effectiveness, and structural margins the design can safely tolerate. For the 737 family, the certified maximum Mach number is 0.82. That means you should not exceed Mach 0.82 in normal operations, because going faster can bring on excessive airframe buffet, loss of control effectiveness, or structural limits being approached. The other values would push beyond or fall short of the certified limit: speeds higher than 0.82 risk surpassing the design limits, while a speed like 0.78 would be below the allowable maximum, unnecessarily restricting performance.
