• A. Forward of the Forward CG Limit
• B. Forward of the Rearward CG Limit
• C. Forward of the Rearward Limit
• D. Aft of the Rearward Limit

Answer: (C)

When checking for a possible aft (rearward) excursion of the CG, you test the most aft position the CG could reach under extreme loading. The way to induce the largest aft shift is to minimize the forward moments, i.e., reduce the weight of loads that lie ahead of the rearward limit. By computing those forward-of-the-rearward-limit items at their minimum weights, you create the worst-case aft CG scenario. If the resulting CG still stays within the rearward limit, then even in extreme conditions the aircraft won’t exceed it. So, the items that should be computed at minimum weights are those located forward of the rearward limit.
