What equipment must be installed in an aircraft when weighed to determine its empty weight center of gravity?

• A. All equipment listed in the Aircraft equipment list as 'Required Equipment' or as equipment that is permanently installed.
• B. Only essential flight equipment.
• C. Only payload and fuel.
• D. No equipment is required.

Answer: (A)

When weighing to determine empty weight and its center of gravity, you must weigh the aircraft with everything that is normally installed for operation. That means including all equipment that the manufacturer lists as required or that is permanently installed on the airplane. These items become part of the aircraft’s weight and influence the balance, so excluding them would give an inaccurate empty-weight CG. Items that aren’t permanently installed or aren’t required for flight can be removed and should not be included in the empty weight calculation. So the correct approach is to include all equipment designated as Required Equipment or permanently installed in the Aircraft Equipment List.
