weight balanceFAA-published question bank (Private Pilot, 2008)
Which items are included in the empty weight of an aircraft?
A
Unusable fuel and undrainable oil.✓ Correct Answer
B
Only the airframe, powerplant, and optional equipment.
C
Full fuel tanks and engine oil to capacity.
Explanation
The Weight & Balance Handbook explains that an airplane's empty weight includes the airframe, engines and fixed equipment plus unusable fuel and undrainable (residual) oil; newer 'basic empty weight' figures also include full engine oil. It never includes usable fuel in full tanks, and it is not limited to airframe, powerplant and optional equipment.
