The requirement 'No payload aft of Station 935' applies when engines are removed.

• A. Only for large aircraft
• B. True
• C. False
• D. Only with QEC removed

Answer: (B)

When engines are removed, the aircraft’s weight distribution changes, shifting the center of gravity toward the tail. To keep the aircraft within safe CG limits during tow operations, the aft payload must be restricted. The rule that forbids any payload behind Station 935 is a specific safeguard designed to prevent the center of gravity from becoming too aft when the engines are removed. If payload were allowed behind that station, it could push the CG beyond the aft limit and compromise controllability and stability during towing or braking.

This constraint is not tied to aircraft size or to removing other components like the QEC; it specifically addresses the situation of engine removal. Therefore, the statement is true: the requirement applies when engines are removed.
