The aircraft lavatory and wastewater system is quite interesting, making it possible to have a functioning restroom for passengers while traveling at extreme altitudes. While there are rumors that waste is simply dumped out of the aircraft during flight, this is simply not true. Rather, the wastewater system relies on a transfer chain and various assemblies to effectively and cleanly function. In this blog, we will discuss how the airplane water and wastewater system functions, allowing you to better understand how lavatory service is provided while in flight. Read more >>

Aircraft are regularly subject to countless stressors during flight operations, requiring robust construction and advanced systems capable of monitoring health and operational conditions. Vibration is often a major stressor faced by aircraft, stemming from various sources. If left unchecked, vibration has the potential to cause cracking, avionic failure, or even a loss of engine performance. As metal structures continuously become fatigued from vibration, engines may reach a point where they risk failure. As a result, it is critical that all pilots understand the importance of monitoring aircraft vibrations and how such procedures may be carried out. Read more >>

Designed to record various electronic instructions sent between an aircraft and its parts, flight data recorders (FDR), commonly referred to as ‘black boxes,’ are capable of retaining data received from various areas of an aircraft. Typically coupled with a cockpit voice recorder (CVR), flight data recorders and their combined components are vital tools for investigating any incidents or accidents that have occured to or on a particular aircraft. Painted a vibrant orange color for ease of identification, flight data recorders and their implementation in aircraft are necessary for obtaining valuable insight on how an aviation accident or incident occurred.

A flywheel is a common machine component, capable of storing rotational energy for later use. When the machine reaches a point where the supply power is inefficient for operations, the flywheel will release its stored energy. Within a standard internal combustion engine, for example, the fluctuating torque produced by the crankshaft during a complete cycle will cause the shaft to have a change in its angular velocity. Through the implementation of a flywheel, inertia mass is provided at the end of the shaft so that the torque will become more balanced. Read more >>

When an aircraft is transporting individuals over long distances, it is important that passengers have access to facilities such as lavatories and aircraft galleys for the means of providing a comfortable experience for all. In order for passengers and crew members to take advantage of the restrooms, coffee and tea makers, sinks, and other facilities and equipment of an aircraft, water must be managed and supplied to each. In this blog, we will discuss the water and waste system of aircraft, allowing you to better understand how potable water is supplied to facilities and how wastewater is removed and stored during a flight operation.
