In this chapter, you are going to learn the mass terms used in Mass & Balance calculations of an aircraft. But first, what is mass? Mass is the quantity of matter in a body and is expressed in kilograms. For example let’s consider a person having a mass of 80 kg and an aircraft having a mass of 50000 kg. When Earth’s gravity acts on these objects, a force called weight is being created and is defined as the force exerted on a body by gravity which is expressed in Newtons. Let’s now calculate the weight of the two masses. We are going to use the formula Weight = mass x gravity. Acceleration of gravity is 9.81 m/s2 for Mass and Balance purposes but a nominal value of 10 m/s2 is frequently used in exam questions. Weight of a person having a mass of 80 kg is, 80 kilograms times the gravity 10 meters over second squared is equal to 800 Newtons. And the weight of the aircraft is calculated as 50000 kilograms times 10 meters over second squared is equal to 500000 Newtons.
