When dealing with electrical wires, there are many ways in which they can be connected and repaired based on the needs of the system and the application at hand. For repairing wires specifically, it is most common to solder or crimp terminals, the former being best for splicing two wires while crimping is most suitable for long-lasting repairs. Despite crimping potentially presenting the more effective solution, things can go wrong fast if one does not carry out the crimping process correctly. As different crimp terminals require varying tools, it is important to have a general understanding of what to do when you are preparing to repair wires.

Oil leakage in aircraft is a serious problem, especially in small aircraft from brands such as Piper, Diamond, Cirrus, Beechcraft, Cessna, or Mooney. These aircraft have the potential of facing engine failures, usually resulting from extensive wear and tear over time or misalignment when installed in the factory. The engine of a small aircraft is a delicate and vital part, and to avoid unwanted delays during take-off or landing, you should ensure the engine is regularly maintained to keep it running smoothly. The engines of these small aircraft are usually equipped with piston-driven powerplants which means that they operate through internal combustion. Moreover, a piston engine is used because it requires less space and provides more efficient performance when compared to larger turboprops or gas turbines. However, the design of lightweight pistons and valves can lead to potential spills and leaks during take-offs and landings.

Most people don't notice their home or office's electrical system until it malfunctions. This is because both residential and commercial electrical systems are designed to be safe, redundant, and usually untouched. Over the years, engineers have continued to advance the safety profile of circuits while also ensuring systems are easy to access when reset or maintenance is required. In the past, fuses and fuse boxes were the most common method of protecting an electrical circuit, later being replaced by the electrical service panel, which is widespread in use today. In this blog, we will discuss everything you need to know about electrical service panels, including their design, function, and common problems that may be encountered.

A Voltage Regulator produces a fixed output voltage of a particular preset magnitude that remains constant regardless of changes to load conditions or input voltage. You can find voltage regulators stabilizing the DC voltages for computer power supplies and even in motor vehicles by matching the output voltage of the generator to both the electrical load and the charging requirements of the car battery. To become more familiar with voltage regulators, this blog will cover different types, distinguishing characteristics, and their importance for a number of applications.

Roller bearings are a type of bearing that carry a load by placing rolling elements between two bearing rings, or races. The structure of the races allows the rolling elements to move with little rolling friction and sliding. These bearings are often found in aviation cargo systems, solar panels, power houses, and engines. Roller bearings serve a particularly important role in engines as they support the crankshaft and allow rotation during engine operation. Moreover, they have an increased load capacity and can be used under varying temperatures. Roller bearings come in different types with specified functions, so selecting the one that best fits your application is important.

At the altitude range that most aircraft operate in, air pressure and oxygen density is often at a level that is unsafe for humans due to the risks of hypoxia. While some aircraft remedy this situation with portable oxygen systems for crew members and pilots, such methods are less optimal for larger airliners with many passengers. In those instances, the passenger aircraft utilizes pressurization, that being when cabin pressure is controlled to provide passengers with a safer environment that is closer to sea level conditions. As a reliable method that has long kept passengers safe and comfortable during flight, understanding the aircraft pressurization system can be useful for any interested individual or aircraft engineer.

The Airborne Collision Avoidance Systems (ACAS) was introduced to minimize the risk of mid-air and near mid-air collisions between aircraft. It serves as a last-resort safety net regardless of any separation standards. ACAS II, the most modern version, is a system based on Secondary Surveillance Radar (SSR) transponder signals. ACAS II interrogates the Mode C and Mode S transponders of surrounding aircraft and uses their replies to track their altitude and range, issuing alerts to the pilots as needed. Unfortunately, ACAS II will not detect aircraft that do not have transponders equipped and will not issue resolution advice for traffic without an altitude reporting transponder.
