Ground Power Units (GPUs) are essential in aviation and aerospace industries. They provide the necessary electrical power needed to aircraft on the ground, saving fuel and reducing wear and tear on aircraft engines. These units are critical, especially when an aircraft's engines are not running and its auxiliary power unit (APU) is not in use or unavailable. With this in mind, understanding the working principles and functionalities of GPUs can offer insights into their importance and versatility in various applications.

Flaps are an integral part of an aircraft's wing design, serving various purposes that significantly impact flight performance and safety. As movable surfaces that can be extended or retracted from the trailing edge of the wing, they play a vital role in enhancing an airplane’s performance during takeoff, landing, and other critical phases of flight. To better understand these aerodynamic devices, we will delve into the functions of wing flaps, as well as their influence on aircraft operations.

In the realm of aviation, an attitude and heading reference system (AHRS) is an important element of many modern aircraft designs, allowing for attitude information related to roll, pitch, and yaw to be offered to pilots and flight systems alike for more efficient and safe operations. While some aircraft models achieve these readings through the use of inertial measurement devices such as gyroscopes, the consistent upgrades and advancements made to AHRs over the years has allowed them to be a very beneficial option that is compatible with flight deck displays, flight controls, and other such aircraft systems.

When operating aircraft with gas turbine engines, a starter unit is often required to help the engine attain the self-sufficient speeds necessary for standard operations. Start units come in a variety of types, and they are all considered Ground Support Equipment (GSE) as they are operated by airlines and ground handling agencies that utilize the unit during the final boarding procedures before departure. One of the most common types of unit is the air start unit (ASU), that of which may be found at most airports across the globe. In this blog, we will discuss the general design and functionality of the air start unit so that you can better understand its importance.

Stalling is a condition that no pilot wants to face, referring to an instance where an aircraft surface is not able to maintain smooth airflow, resulting in a decrease in lift. Stalls may occur through various means, and they are a hazard as they cause aircraft to sink in the atmosphere when there is not enough lift to overcome weight. While stalls are most often faced by the main wings of an aircraft, they can also occur around the tailplane. While tailplane stalls are not often discussed, they present a major threat to pilots and passengers. As such, having an understanding of how they come about, and how to recover from them, is highly important to maintaining safety across flight operations.

When working with fluid applications such as plumbing, it is paramount that ample flow management is in place to ensure that all materials move exactly how they need to through a system. One undesirable issue that may be faced in a system is backflow, that of which is when materials begin to move in the opposite direction as a result of pressure changes. While this takes away from steady performance, the backflow of substances may also lead to clogging, excess pressure, and other issues like contamination. As such, one should always take advantage of components that prevent backflow, such as a backflow preventer or check valve. While both of these devices operate on the same principle, their overall objective differs, making it important that one understands their differences and distinct applications.

While modern aircraft often have the tools and equipment required for instrument flight rules (IFR) for instances in which a visual reference is not safe, it can be highly beneficial to maintain sight out of the vehicle when possible. During conditions such as heavy rain, beadlets of water can gather up on surfaces, possibly obstructing the pilot’s view outside of the windshields. To remedy such issues, aircraft feature various forms of windshield wipers and systems.
