Which boundary defines the forward limit for loading calculations?

• A. Rearward CG limit
• B. Forward CG limit
• C. Center of gravity
• D. Maximum gross weight

Answer: (B)

The forward limit for loading calculations is defined by the forward center of gravity limit. This boundary sets how far forward the aircraft’s CG can be while still satisfying controllability and stability requirements. When you perform loading calculations, you determine the CG from the total weight and moments and make sure it stays between the forward and aft CG limits. If the CG goes forward of this limit, the aircraft may have insufficient elevator authority to rotate on takeoff and may be harder to flare or pitch up safely. Conversely, if the CG is too far aft, stability can be degraded, but that’s governed by the aft limit.

The other options don’t fit the question: the rearward CG limit marks the aft boundary, not the forward one; the center of gravity is the actual balance point, not a boundary; maximum gross weight is about total weight, not the CG position.
