Title: Calculate changes in empty weight and empty weight CG after aircraft modifications.
Course: Aviation Maintenance Technology II (20114-II) > Section: Demonstrating Aircraft Weight and Balance Procedures

Calculation should include the CG formula, accounting for changes to empty weight (e.g., adding, removing, and relocating equipment, radios, fuel tanks, seats, and other components). Changes to empty weight produce changes in total weight and moment of the aircraft, and this will result in a change in the CG. There is a range that is provided by the aircraft manufacturer and the aircraft must stay within this range to function properly and safely.

Process/Skill Questions:

- When should CG be recalculated?
- How can shifting weight change the moment and CG of an aircraft?
