When engine(s) or QEC(s) are removed, which condition shall be complied with prior to towing?

• A. No payload aft of station 935
• B. No payload forward of station 935
• C. No external stores
• D. No payload limited

Answer: (A)

When towing, keeping the aircraft's weight distribution within approved limits is crucial because there’s no thrust to help stabilize or steer the airplane. Removing engines or QEC modules takes away a lot of the forward weight, which tends to shift the center of gravity toward the tail. To prevent the CG from moving too far aft and compromising stability and control during tow, any payload placed behind station 935 must be avoided. This keeps the aircraft within the approved towing envelope, preserving adequate elevator authority, stability, and tail clearance. Other restrictions (like payload in front of that point, or removing stores) don’t address this specific stability concern during engine/QEC removal towing.
