Check valves have several other names, such as one-way, non-return, or clack valves. They have a design that is used for the guarantee of unidirectional flow. With this, they are often used as a preventive measure to avoid overflow, backflow, and other hazardous operating conditions. As such, they are found in a wide variety of fluid handling systems. A few check valve applications are irrigation systems, oil and gas extraction and processing equipment, potable water systems, standard and critical power generation and distribution equipment, subsea operation systems, wastewater treatment facilities, and more.

Aircraft are robust and advanced vehicles, yet just like an automobile, they require regular inspections and maintenance to ensure that all systems and parts are airworthy and functioning as intended. As required by the FAA, aircraft must undergo a series of inspections, each of which vary in their thoroughness and objective. To help you better understand the basic inspection requirements of an aircraft, we will discuss common aircraft inspections in brief detail.

Since the dawn of aircraft travel, navigation-based systems have been one of the most important features within aircraft, allowing pilots to traverse the sky with ease. Equipped with a number of instruments that enable pilots to navigate large and small aircraft alike, this blog will cover two of the most important types. The first instrument is the Course Deviation Indicator (CDI), and the second is the Omnibearing Selector (OBS).

While floating down a runway may not sound like a problem, it is for pilots and aircrew alike. Whether you are a pilot with years of experience or a rookie flier, floating down past your touchdown point is a problem all pilots face at some time or another. In this blog, we will be providing a brief overview of what floating down the runway entails, how to prevent it, and how to stop it if you find yourself in this predicament.

As piston aircraft engines operate through the combustion of fuel-and-air mixtures, a great amount of heat is generated over time which can pose hazards to surrounding components if left alone. While many piston aircraft utilize the flow of air to cool down many internal components, the general assembly of such aircraft engines will often deter equal cooling to all cylinders. In order to achieve more uniform cooling to mitigate the formation of hotspots, most air-cooled piston engines utilize structures known as cowling and baffles.

Bolts are a mechanical fastener that feature an external male thread, capable of mating with a matching preformed internal thread to secure and assemble two or more parts together. As one of the most common fasteners used for assemblies ranging from DIY home projects to advanced aircraft construction, there are many types available that one may procure for their given requirements. The carriage bolt and lag bolt are two common types, each of which present their own unique characteristics and advantages. To help you best understand the difference between carriage bolts and lag bolts, we will provide a brief overview of each in regard to how they are designed, how they serve assemblies, and more.

For an aircraft to achieve and maintain flight, they utilize the combustion of jet fuel and air mixtures which produces the force necessary to drive systems and generate propulsion. While jet fuel is a fuel, it is not interchangeable with the types of fuels or gasoline that power vehicles such as automobiles. At the same time, other vehicles cannot use jet fuel as well due to its composition and characteristics. In this blog, we will discuss jet fuel and gasoline, allowing you to better understand their differences and why jet fuel in particular is so important for the functionality of aircraft.

Light aircraft, perhaps surprisingly, can be maneuvered on the ground with relatively little difficulty. The key is to tow the aircraft without doing damage to the aircraft or yourself. For this reason, propeller manufacturers warn against pulling an aircraft around by its propeller. However, if an aircraft has struts, it's fine to move the aircraft around by those. That said, if you have to steer the aircraft in one direction or another, simply pulling or pushing it won’t work. This is where the tow bar comes into play. In this blog, we will cover tow bars and their uses.

A modulator valve is a component inside an automatic transmission that controls shifting. While most modern transmissions don’t typically use them, they are very common in older transmissions. In this blog, we will discuss the way modulator valves work, how to tell if yours is faulty, and what to do if it fails.

            When conducting ground operations with an aircraft featuring a nose wheel steering system, control is often provided to the pilot through the flight deck. Depending on the size of the aircraft, various parts and components may be present to allow for efficient steering and braking. As aircraft landing and steering systems are crucial for conducting operations on runways and ground surfaces, understanding their types, construction, and functionalities can be extremely useful for any current or aspiring pilots.
