How do you interpret a CG value that is exactly at the forward limit?

• A. It is acceptable if within tolerances; any loading that shifts CG forward beyond the limit would be unacceptable.
• B. It is always unacceptable
• C. It means CG is aft of the forward limit
• D. It indicates the fuel must be increased

Answer: (A)

Being exactly at the forward limit means you’re at the boundary of the permitted center of gravity range. This is acceptable as long as the loading doesn’t push the CG forward beyond that limit. The forward limit is set to ensure the aircraft remains controllable and within structural and handling requirements; any forward shift past it would make the aircraft noncompliant and could reduce elevator authority or alter stability too much. So a CG value on the limit is permissible, but you must ensure future loading, fuel burn, and distribution don’t move the CG forward beyond it. The idea isn’t that you must add fuel or that it’s automatically unacceptable; it’s simply the edge of the allowed envelope, requiring caution with subsequent changes.
