In the realm of aviation, the cockpit of an aircraft is often considered one of the most important elements of the entire vehicle where pilots conduct all operations during a flight. Beyond serving as the area where pilots are situated, the cockpit also contains all display, control, and communication equipment necessary for an aircraft to safely and efficiently fly from liftoff to landing. Cockpits have been a staple of aircraft since the early years of powered flight, and they have been progressively advanced with new and improved features. With all of this, one can understand the cockpit as the brain of the aircraft.

Pressure gauges are important elements of many types of machinery and operations, allowing for pressure to be measured within a space for safety, performance, etc. While pressure gauges are designed to withstand intensive conditions as their job demands it, they cannot withstand every challenging condition, especially those that they are not intended to take on. As such, pressure gauges do run the potential risk of failure, and it is important to know how these failures may come about so that they can best be avoided.

Pneumatic cylinders are mechanical devices that may be found in a wide variety of industries and machinery, serving to generate force through the use of pressurized air. To harness such energy, pneumatic cylinders consist of a piston, piston rod, and cylinder. As air enters one side of the cylinder, pressure will rise, and this will cause the adjustment of the piston in a specific direction. As force continues to develop while the piston adjusts, the piston rod will transmit force to an external object to move it. This explanation of pneumatic cylinders is fairly simple, as there are many other parts that may be present in an assembly, and there are multiple variations of cylinders that one can choose from. As such, we will offer a brief overview of pneumatic cylinders so that you may become more familiar with them.

A critical aspect of navigating an aircraft is ensuring you are heading in the right direction, and pilots can maintain their flight path by consulting the heading indicator. While heading indicators are recognized for being vital and reliable, it is important to understand what they are showing you and how they work. To begin, the heading indicator is referred to as a primary flight instrument, belonging to a group of six basic cockpit instruments that every aircraft is equipped with. In a typical cockpit, it is located in the middle of the instrument panel, just below the artificial horizon.

Relays are important electronic devices that open and close circuit contacts, and the solid state relay (SSR) is a specialized type capable of performing its job without using any moving parts. Solid state relays utilize semiconductor elements to manage circuits, and while performing the same duties as a conventional electromechanical type, SSRs face much less wear and tear due to their motionless design. Despite their various advantages, solid state relays perform best under specific conditions and applications, making it important to have a better understanding of their design, functionality, and use before making a purchasing decision.

In order for an electronic device to be controlled with any level of accuracy, the underlying circuit must be equipped with the appropriate elements to facilitate whatever action is required. One of the most critical needs of both control and monitoring applications is current sensing. This measurement is crucial as both a standalone reading and when used in conjunction with other automation components. Current sensing may be completed through a number of different mechanisms, each producing varying levels of accuracy and isolation. In this blog, we will discuss everything you need to know about current sensing and what tools can be used to achieve it.

The aircraft engine is a powerful apparatus, utilizing the compression and ignition of fuel-and-air mixtures to create the power needed to drive the systems necessary for flight and thrust generation. With constant ignition and various moving components, the engine will quickly face various issues such as intense heat levels, friction, contaminate build-up, and much more. If these issues are ignored, they could quickly lead to unsafe conditions as parts lose efficacy and eventually break down or fail. As such, a solution must be in place to deter the various negative byproducts of engine operation. For this, a majority of modern aircraft rely on what is known as the aircraft oil system.

A bearing is a cylindrical piece of machinery that functions to reduce friction between two flat surfaces in contact. Within aircraft, bearings function to hold journals and rods in place and absorb shock during machine operations and landings. They work to prevent damage from heat and pressure by reducing friction between two points of contact. Bearings also serve the purpose of protecting vital components of aircraft, including engines, actuators, and missile launchers by allowing for greater mobility (sometimes a full 360 degrees). The part of machinery that needs bearing support is inserted into the circular opening of the bearing, and the bearing rotates around it.

For almost two decades, airlines have moved away from conducting in-house maintenance procedures and have begun opting for third-party providers to complete their services. As there are many independent service companies, a majority maintain relatively stable rates and ensure enough capacity to accommodate aviation’s needs. However, with maintenance, repair, and overhaul (MRO) procedures undergoing major modifications, many airlines are ditching service providers and are carrying out such operations themselves.
