Airplanes are genuine wonders of our modern time, helping us connect the globe as such vehicles can traverse several thousands of miles in just hours. While being so advanced, some may wonder why aircraft are without certain features that a typical automobile would have, such as being completely devoid of a reverse gear. Most of the time, one will see a ground vehicle tug attached to the aircraft which is responsible for the aircraft's ground movement in certain areas and during specific operations. Although aircraft are more than capable of moving on the ground on their own during operation, pilots often avoid taking advantage of such capabilities for certain reasons., In this blog, we will discuss how an airplane can reverse without having a reverse gear and why they utilize the help of a ground vehicle for ground movement. Let us begin by looking at how airplanes can reverse on their own.

Switches serve as drawbridges in electric circuits. When the switch is closed, the “bridge” is down, allowing electric current to flow around the circuit. Similarly, if the switch is opened, the “bridge” is up and no current flows. Essentially, they function to activate or deactivate a circuit at any given time.

When equipment and systems that feature rotation are under operation, they constantly generate both radial and axial loads. With movement between these rotating components, friction is also created. If left to their own devices, these loads and friction may cause damage that can lead to inevitable failure of the entire assembly. To mitigate this chance and protect equipment, antifriction bearings are implemented.

Many aircraft engines create propulsion for flight through the combustion of fuel and frequent moving parts. As a result, engines typically generate high amounts of heat and friction. This heat can spread to surrounding components and if left unchecked, could even damage the system as a whole. Through the use of aircraft engine oil, heat and friction caused by normal operation can be mitigated. The benefits of engine oil are so useful that without it, an aircraft engine may fail within a matter of minutes.

Avionics test methods are typically restricted to singular fashion testing. This defines the removal of a faulty avionic component from the aircraft, usually an avionics box, in order for it to be tested at a repair station. The main issue with this process is that it cannot accurately reflect the malfunctioning unit in tandem with its associated aircraft systems. Therefore, if a problem does not occur during testing and cannot be recreated by the service facility or an avionics technician, it is classified as a No Faults Found (NFF) case.
