What is the G-load limitation range for an aircraft in the Normal Category?

• A. -1.52 to 3.8 Gs
• B. 0 to 2.5 Gs
• C. -2.0 to 4.0 Gs
• D. -3.0 to 3.0 Gs

Answer: (A)

G-load limits describe the flight envelope the airplane is certified to tolerate, specifying how much load factor the structure can experience in both positive (upward) and negative (downward) directions. For a Normal Category aircraft, the certified limits are +3.8 Gs and -1.52 Gs, so the allowable range is from -1.52 to 3.8 Gs. This range ensures safety during typical flight, turbulence, and standard maneuvers, while not permitting the higher or more extreme loads needed for aerobatic or utility flying. Choices that omit negative Gs, or that extend beyond these certified values, don’t accurately reflect the Normal Category’s limits. Hence, the range -1.52 to 3.8 Gs correctly describes the Normal Category G-load limits.
