Placing avionics and associated antenna systems forward of the center of gravity limit will affect which parameter?

• A. Aircraft weight distribution characteristics
• B. The center of gravity
• C. Wing structural load
• D. Cabin pressurization schedule

Answer: (B)

Weight distribution along the longitudinal axis determines the center of gravity, the aircraft’s balance point. Placing avionics and their antenna systems forward of the center-of-gravity limit adds weight ahead of the current balance, shifting the overall center of gravity toward the nose. This change directly affects the center of gravity location, moving it forward. A forward CG alters handling characteristics—typically increasing longitudinal stability but reducing elevator effectiveness and narrowing the allowable envelope if you approach the forward limit. The other parameters aren’t directly changed by moving weight forward in this way.
