Aircraft instruments are crucial to safe flight operations, ensuring that pilots are able to consistently monitor various flight conditions and characteristics that are needed for proper operations. The turn and slip indicator in particular is an instrument that combines the turn indicator and slip indicator into one single device. The turn indicator is useful for discerning the rate of change in regard to the aircraft’s heading, while the slip indicator is used to determine if the aircraft is in coordinated flight. As both readings are quite useful for pilots during flight operations, it is important that one understands how they garner data and what their readings mean.

The piston pump plays a critical role in the hydraulic systems of civil aircraft where it is used to convert mechanical energy into hydraulic energy. This energy is then used to supply power to the actuators to fulfill the flight posture adjustment, retract and extend the landing gear, and brake. The most common type of piston pump in aviation is the swash plate type axial piston pump, due to its compact design and simplicity. Pumps of this type are capable of working at extremely high pressures while maintaining high overall efficiency.

When electricity was first introduced commercially for lighting and powering motors, there was heavy debate on whether DC or AC power should be used. While DC power could provide an unchanging polarity that could be steadily relied upon for wiring, AC power would constantly shift between positive and negative polarity. While one may think that this method of operation makes AC power detrimental for powering systems, the changing of voltage allows for voltage to be adjusted much easier and creates the ability for low amps to be sent over great distances with a small amount of wiring. Due to these advantages, AC powering quickly became the standard for most commercial buildings and private homes across the globe.

The fuel system is paramount to the operation of an aircraft, providing the ability to store, manage, and transport fuel for the engine. For the aircraft fuel system to function optimally, it must be capable of delivering a sufficient amount of fuel throughout all stages of the flight, accommodating for any changes in altitude, temperature, speed, direction, and more. While a light aircraft may feature a more simplistic fuel system, larger airliners implement a series of advanced components in order to properly operate. In this blog, we will discuss some of the main components of the aircraft fuel system, allowing you to best understand how they function.

There are distinct advantages to flying at high altitudes. These include decreased drag, faster true airspeed, and higher tailwinds (when applicable). However, these advantages bring with them a major disadvantage for any aspirated engine: a lack of air. Air pressure decreases at higher altitudes, and does so quickly. For example, at 18,000 feet elevation, 50% of the entire atmosphere is beneath your aircraft. This means there is much less oxygen for your engine to burn, resulting in a deficiency of horsepower. So, how do aspirated engines, engines that require oxygen to function, solve this problem? There are multiple ways, one of which is called turbo-normalization.

During standard engine operation, heat can quickly increase due to moving parts, combustion of fuel, and other mechanical processes. This heat can build up to dangerous levels if unchecked, damaging components and systems alike. One major way in which engines are typically cooled on an aircraft is through the use of colder air within the atmosphere that is directed throughout components and systems. Aircraft engine baffle seal material is an important element to engine cooling for piston powered aircraft, allowing for airflow regulation through an engine compartment. In this blog, we will discuss what engine baffles are, as well as how they cool aircraft engines.

A National Stock Number (NSN) is an officially recognized moniker given to any item of supply that is in wide use throughout the federal supply system. It is sometimes referred to as a NATO Number and is comprised of a series of numbers used to identify a single unique item. When the NSN is assigned, data such as item name, manufacturer part number, unit price, and physical characteristics are all taken into consideration to provide an accurate set of digits to describe the part. National Stock Numbers are a critical aspect of the logistics supply chain of militaries throughout the world for their management, movement, storage, and disposal of materials.

When you’re headed to work on a cold winter’s morning and start the car for your daily commute, you may have noticed a blue light on your dashboard. This light denotes that your coolant temperature is low, meaning your car has not yet heated up. While this little blue light is not necessarily cause for concern, it does indicate that your car is not operating at its full potential. Just as your car needs time to heat up, so too does an aircraft. The difference is that performance issues on the ground are much more manageable than in the air, so preheating the aircraft engine is not something to take lightly.
