- Calculating the Weight and Balance of an Aircraft Step 1: Calculate the empty weight and moment of your aircraft. The weight and moment of each aircraft are different from the next. This information is provided to you
- Step 2: Determine the weights of everything that has been loaded. This covers the pilot, all passengers, baggage, and the fuel that will be used
- however, it does not include the pilot’s salary.
- Step 3: Determine the moment of inertia for the load You will discover one of the following in Chapter 6 of the POH:
Empty weight (EW) is the sum of the manufacturer’s empty weight (MEW) plus any standard items (SI) and any operator items (OI), with EW = MEW + SI + OI being the manufacturer’s empty weight as constructed. The EW is computed for each aircraft series and for each unique configuration of an aircraft, and it is checked by weighing the aircraft on a regular basis to ensure accuracy.
How is the new empty weight calculated?
- The new empty weight is calculated by subtracting the empty weight reported on the most recent weight and balance report from the weight of the things that have been added plus the weight of the items that have been removed to arrive at the new empty weight.
- When the weight of the load items is added to the new empty weight, the total weight may be compared to the weight limit specified in the aircraft specifications.

What is an empty weight airplane?
This is referred to as the fundamental empty weight. This refers to the airplane in its whole, including all of its components, as well as regular working fluids, useless fuel, and other such items. Basically, it’s just the airplane out on the tarmac by itself.
How is aircraft weight calculated?
- The weight of an airplane that engineers are building is determined in a variety of ways.
- When it comes to weight, the overall weight W of an airplane is just the total weight of all of the aircraft’s various components.
- W = w(fuselage) + w(wing) + w(engines) + w(payload) + w(fuel) + w(fuselage) + w(wing) + w(fuselage) + w(wing) + w(fuselage) + w(fuselage) + w(fuselage) + w(fuselage) + w(fuselage) + w(fuselage) +
Which items are included in the empty weight of an aircraft?
Standard empty weight (GAMA) is the total weight of the aircraft, including the airframe, engines, and all items of operating equipment that have fixed locations and are permanently installed in the aircraft, such as fixed ballast, hydraulic fluid, unusable fuel, and full engine oil, in addition to the weight of the aircraft’s passengers and cargo.
Does aircraft empty weight include fuel?
The basic aircraft empty weight is the weight of the airplane when it is without carrying people, luggage, or fuel that can be used. The basic operating weight of an airplane includes all of the fluids required for the aircraft to operate, such as lubricants, hydraulic fluid, coolant, water, and gasoline, among other things.
How do you calculate landing weight?
Landing Weight: The weight you have when you land; it is computed by subtracting the weight you took off from the weight you have when you land.
What constitutes the difference between basic empty weight and licensed empty weight?
- It is the normal empty weight plus any extra equipment that constitutes the basic empty weight.
- It should be noted that the basic empty weight does not include any useable gasoline, but does include full oil.
- Accordingly, the licensed empty weight comprises the standard airplane, optional equipment, full hydraulic fluid, unusable gasoline, and undrainable oil, in addition to the basic airplane.
How is aircraft weight and balance calculated?
Weight and balance are important in technique.
- Take note of the empty weight of the aircraft in the pilot’s operating manual, and then calculate the weights of the passengers, their luggage, and fuel
- To get the moment, multiply each weight by the arm, which is the distance between the reference datum and the weight.
- To obtain the total weight, add all of the weights together.
Does basic empty weight include crew?
The term ″useful load″ refers to the difference between the gross weight and the basic empty weight when a vehicle is fully loaded. It consists of the flight crew, useable fuel, drainable oil, if any, and the cargo, among other things.
How much oil is included in the empty weight of an aircraft?
Plane A or B has a gross weight in excess of 2,300 pounds, which is the maximum allowed. Airplane A has an empty weight of 1,200 pounds and carries 8 quarts of oil (7.5 pound).
How do you find the empty weight of center of gravity using different formulas?
The following is the formula for calculating the center of gravity (CG):
- Calculate the weights and arms of all of the mass contained within the airplane
- To compute moments, multiply weights by arms for all of the mass in the system.
- Add up all of the mass’s moments and divide by 100.
- To find the overall arm of the aircraft, divide the entire moment by the whole mass of the aircraft.
How do you weight a Cessna 172?
Calculate the weights and arms of all of the mass contained within the aircraft. To compute moments, multiply weights by arms for all of the mass in the system. Add all of the mass’s seconds together to obtain the total. To find the overall arm, divide the entire moment by the whole weight of the aircraft.
