Stress | Aviation Physics

Whenever a machine is in operation, be it a simple machine like a lever or a screw, or a more complex machine like an aircraft piston engine or a hydraulically operated landing gear, the parts and pieces of that machine will experience something called stress. Whenever an external force is applied to an object, like … Read more

Aircraft Safety, Ground Operations, and Servicing

Aircraft maintenance technicians devote a significant part of their work to aircraft ground handling, servicing, and the operation of support equipment. These activities require more than technical skill alone, since many procedures involve hazards that can affect both personnel and aircraft. Safe practices during servicing, taxiing, engine run-up, towing, and the use of ground support … Read more

Aircraft Drawings and Technical Graphics

The exchange of ideas is essential in aviation, especially when aircraft parts and assemblies must be built, inspected, repaired, or installed correctly. Written or spoken descriptions alone are often not precise enough to describe the exact shape, dimensions, or arrangement of an object. To avoid misunderstanding and ensure accuracy, drawings are used as a universal … Read more

Simple Machines | Physics for Aviation

A machine is any device with which work may be accomplished. For example, machines can be used for any of the following purposes, or combinations of these 5 purposes: Machines are used to transform energy, as in the case of a generator transforming mechanical energy into electrical energy. Machines are used to transfer energy from … Read more

Force, Work, Power, and Torque | Aviation Physics

Force Before the concept of work, power, or torque can be discussed, we need to understand what force means. According to the dictionary, force is the intensity of an impetus, or the intensity of an input. For example, if we apply a force to an object, the tendency will be for the object to move. … Read more

Energy | Physics for Aviation

Energy is typically defined as something that gives us the capacity to perform work. As individuals, saying that we feel full of energy is an indicator that we can perform a lot of work. Energy can be classified as one of two types: either as potential energy or kinetic energy. Potential Energy Potential energy is … Read more

Matter | Physics for Aviation

Matter is the foundation, or the building blocks, for any discussion of physics. According to the dictionary, matter is what all things are made of; whatever occupies space, has mass, and is perceptible to the senses in some way. According to the Law of Conservation, matter cannot be created or destroyed, although it is possible … Read more

Fire Protection | Aviation Safety

Requirements for Fire to Occur Three things are required for a fire. Remove any one of these things and the fire extinguishes: Classification of Fires For commercial purposes, the National Fire Protection Association (NFPA) has classified fires into three basic types: Class A, Class B, and Class C. A fourth class of fire, the Class … Read more

Servicing Aircraft

Servicing Aircraft Air/Nitrogen Oil and Fluids Checking or servicing aircraft fluids is an important maintenance function. Before servicing any aircraft, consult the specific aircraft maintenance manual to determine the proper type of servicing equipment and procedures. In general, aircraft engine oil is checked with a dipstick or a sight gauge. There are markings on the … Read more
