Hydraulic power units (HPUs), a type of ground support equipment, are crucial for the testing and maintenance of aircraft systems. But like any machine, they cannot be used if they are not in peak condition. This is where preventative maintenance comes into play. By maintaining your HPU prior to its breaking down, you will be able to rely on it whenever you need it. In this blog, we will look at the four most important aspects of HPU maintenance: checking and changing oil, cleaning filters and strainers, checking for leaks, and lubricating the motor.

The aircraft radar system has become a critical asset to countless operations ranging from air traffic control to general navigation. Through their implementation and use, radars have increased the safety and operational efficiency of the entire industry. While some may be familiar with the basics of radar technology, others may not be aware of how they are used for aviation and what benefits they can provide.

Temperature sensors have a wide range of uses in many different applications. Some devices, like the equipment used to produce life-saving medicine, require highly accurate and responsive temperature sensors. On the other hand, applications like the thermometer in your car do not need to be as accurate or responsive. As such, there are many types of temperature sensors with varying accuracy and responsiveness. The four most common types of temperature sensors are negative temperature coefficient thermistors, resistance temperature detectors, thermocouples, and semiconductor-based sensors.

Since the advent of aviation, a great number of aircraft engine types have come about to achieve heavier-than-air flight. With types such as the turboprop engine, radial engine, and other combustion engines all common to aviation, a variety of aircraft with varying applications and designs may be accommodated for. The radial engine in particular is one of the oldest forms of aircraft engines, and it can still be found on a number of models to this day. Due to its importance and continued use for general aviation, understanding the radial engine’s functionality and make-up can assist in the operation and maintenance of such engines.

The role of an aircraft fuel system is to store fuel and supply it to the engines and auxiliary power unit. Aviation fuel is converted into heat energy and subsequently kinetic energy in the engine to power an aircraft. All engine-powered aircraft must have a fuel system onboard, the basic requirement of which is to provide a continuous flow of uncontaminated fuel to the engines at a pressure and flow rate to sustain operation at any attitude. The aircraft fuel system is not a single system, but rather a collection of various subsystems. The exact configuration varies from aircraft to aircraft, but the basic principles remain the same.

A pneumatic system is a power transmission system that uses compressed air as a working fluid similar to the way hydraulic systems use liquids. Hydraulic systems are more popular, but there are many advantages to using its pneumatic counterpart to transmit power. The principles in using air are the same as those in using hydraulic fluids, but the results are quite different.

Though both are aviation giants, the civil aviation jet and classic commercial airplane are two distinctly different mechanisms. Commercial airplanes, for one obvious note, can transport fifty or more passengers to a destination while a civil aviation jet, like a helicopter, can transport only a limited amount. Having access to a civil aviation jet is somewhat like having your own personal jet. Many wealthy clients certainly do own their own private line, but the fact is that you do not necessarily need to be in this clientele if you desire to try your experience on a civil aviation jet. There are many airliners and services that offer this advantage. The key is in knowing which line best suits your traveling needs. Both have their pros and cons, but some flight aficionados are more partial to one, Read about the difference, as well as some facts, advantages and disadvantages of both in this article below.

The Cessna 400, also known as the Cessna TTx, is a civil personal transportation aircraft that was manufactured by Columbia Aircraft and Cessna over the years between 2004 and 2018. The Cessna 400 was initially the Columbia 400 while it was manufactured by Columbia Aircraft. In 2009, however, Columbia Aircraft was acquired by Cessna, and the Columbia 400 was renamed the Cessna 400 later in 2013. The Cessna 400 was modeled from the Columbia 300, bringing a Garmin G1000 glass cockpit alongside other system and structural improvements. For optional systems, the Cessna 400 may be outfitted with an ice protection system and wing speedbrakes.

If you have been searching for parts and components for the Cessna 350 Corvalis, ASAP Semiconductor is your one-stop-shop. The Cessna 350 Corvalis, originally known as the Columbia 350 under Columbia Aircraft, is a personal aircraft that was manufactured over the years between 2000 and 2010. The Cessna 350 actually serves as a variant of the Columbia 300, and with it came a more powerful power plant, Garmin G1000 glass cockpit, and more. While the aircraft was originally only called the Cessna 350, Cessna later gave the Corvalis marketing name in 2009 in reference to the town of Corvallis, Oregon which was located near the Cessna plant where the aircraft was produced.
