The complexity of aircraft hydraulic systems depends heavily on the functions it needs to perform. In smaller planes, hydraulics are used to operate constant-speed propellers, landing gear, and wheel brakes. On larger planes, the systems tend to be more complex as they are used to operate flight control surfaces, spoilers, wing flaps, brakes, and other flight critical functionality. The principles of hydraulics are based on Pascal’s law—pressure exerted anywhere in a confined incompressible fluid is transmitted equally, in all directions throughout the fluid, such that the pressure ratio remains constant.

Let’s explore how hydraulic systems work. Hydraulic fluid is first pumped from a reservoir by an electric, or engine operated pump. It runs through a filter to keep the fluid clean, and then passes through a selector valve to relieve pressure. Once it reaches the actuator, the pressurized fluid power is converted into work by the actuators’ piston. The actuator can be single or double acting depending on the requirements of the system. The piston reacts and is able to control aircraft systems, brakes, flight controls, and many other operations. Actuators are the main moving parts in hydraulics; a vital component contributing to overall functioning capabilities.

A hydraulic actuator consists of a cylinder, or fluid motor, that utilizes hydraulic power to facilitate mechanical operation. It gives an output in terms of linear, oscillatory, or rotary motion. An actuator can exert a considerable amount of force since liquids are nearly impossible compress entirely. It consists of a hollow cylindrical tube on which a piston can slide. Some actuators are single acting, meaning fluid pressure is applied to just one side of the piston, causing it to move in one direction. There are also double acting actuators. This term is used when pressure is applied to both sides of the piston; a difference in pressure between the two sides causes the piston to move in the more pressurized direction. Actuators can come in different sizes and shapes depending on the size/weight of the object it needs to move.

Hydraulics have the ability to deliver a great deal of power without occupying too much space or weight. They can be operated quickly, relied on, and are easy to maintain. They do not need electricity to function, which means the chance of a fire hazard are very low, making them a safer option than other systems. Yet, perhaps the main advantage they offer is that they can handle an immense workload, which is invaluable in today’s aerospace engineering.

When we think about being in a comfortable space, the first thing that comes to mind is probably not an aircraft cabin. Most people who fly economy class feel cramped and after a long flight, passengers are often tired and achy. Airlines have sacrificed passenger comfort throughout the years in order to save on costs and fit more seats. With heavy materials and the related fuel consumption, the design has often been centered around savings and maximizing profits. However, making aircraft comfortable for passengers is becoming increasingly economical as technology rapidly develops and consequently increases an aircraft's efficiency. 

The more an airline can save on the vast array of costs associated with flying, the more they can invest in cabins that increase comfort. Innovative technologies and material are used for both the interior and exterior components of an aircraft to improve passenger comfort. Let's take a look at a couple of the aircraft that have utilized these technologies: The Boeing 787 family and the Airbus A350 family.  

The Boeing 787 has a spacious cabin, large windows, and vaulted ceilings. The passenger’s windows are not only larger, but don’t have the traditional panel that slides up and down— passengers can adjust the tint with the press of a button. This technology increases passenger comfort by allowing them to maintain a view of the beautiful aerial scenery while not being blinded by sunlight. The design also incorporates a new air system which adjusts air pressure and humidity, and this leads to reduced fatigue and dryness. A few of the other features include more comfortable seating, large overhead bins, and new lighting systems. Adjustable LED lighting creates a more relaxing environment. The traditional lighting options have often contributed to fatigue. One of the newest technologies to increase passenger comfort is the Boeing 787s ability to sense and dampen turbulence— reducing motion sickness. 

The “Airspace by Airbus” cabin in the A350 family is quiet and comfortable. Airbus Industries was able to achieve its goal of increasing comfort by utilizing various modern technology. It has wider seats, high ceilings, and ambient lighting. The cabin’s air system is refreshed every few minutes and has an optimal cabin altitude of 6,000 ft, reducing the effects of jet lag. Air is also adjusted to comfortable temperatures and humidity. 

Both of these companies have used similar technology to increase airline passenger comfort and reduce the dreaded effects of jet lag while maintaining features unique to their own aircraft. But, none of these improvements would have been possible without the advancements in electrical systems and composite materials.

If you've ever traveled by plane, you've probably had the misfortune of being stuck on the runway past your departure time because of this problem or another. And while it's frustrating to be a passenger stuck waiting for takeoff, it can't be worse than being an airliner with an AOG.

When an aircraft is grounded due to a maintenance issue, it is called an aircraft on ground (AOG) and can accrue many costs for various reasons. Passenger carriers don't lose revenue because passengers are re-booked. However, costs from meals, accommodations, transportation, additional crew costs, mechanics overtime, component shipping costs, and productivity losses all add up and can cost an airline up to $150,000 per hour for any given AOG. In comparison, a cargo carrier can lose revenue if the cargo isn't delivered on time, so they tend to have more support aircraft. Fortunately, there are a few things an airline can do to minimize the effects of an AOG or prevent them. Having regular inspections, following time between overhaul (TBO) and all other original equipment manufacturers (OEM) maintenance and repair schedule recommendations are important in mitigating the risk of having an AOG. Some of the ways that can reduce the costs associated with AOGs are to create a parts stock model and to work with an aftermarket spares supplier to be ready for an AOG and reduce the time it takes to get the part delivered.

The software can help in creating a parts stock model. An airline should start with the reliability of no-go parts because they are category one on the minimum equipment list (MEL). If these parts malfunction, it will cause an AOG. The next step is to create a required level of parts stock. This has been done through a Required Spare Provisioning List (RSPL) model, but they vary in how complete they are.

Some airlines and maintenance, repair, and overhaul (MRO) companies prefer to keep all essential parts and components in stock at their facilities. However, it is sometimes more efficient to outsource with a parts distributor. Keeping a list of part numbers that have reoccurring issues and utilizing predictive analytics can help an airline and their parts distributor prepare for AOGs.

Have you ever wondered how pilots can maneuver through the sky without crashing into each other? It’s mainly due to communications antennas. Aircraft use radio frequencies to navigate and communicate with air traffic control.  Each antenna has different frequencies and applications which determine where on the aircraft they are located. 

When communicating with air traffic control (ATC), these antennas are operating short-range using a very high frequency (VHF) band between 118 MHz and 137 MHz. Since the aircraft is constantly moving, the signal must be sent in all directions to ensure it is received.  These VHF frequencies operate with line-of-sight capabilities, meaning that the range only reaches the visible horizon.  The height of the antenna being used determines what kind of range you get–higher antenna means wider range. 

These antennas can be found either on top of the aircraft or underneath it. They are slightly bent and usually made from white or stainless steel.  The standing wave ratio (SWR) for these should typically be between 1:1 and 1:2; this refers to how well the antenna performs and how much of a reflection is coming off the antenna.  Antennas like these must be grounded well, meaning that they need a strong mounting sheet that will reflect the signal back toward the transmitter.

 Since VHF is only recommended for short distances, the high frequency (HF) band is used for long-range communication needs.  Airliners are equipped with satellites that allow them to have long-range communications while they travel, and to provide accommodations like wireless internet to their passengers. These airliners are supplied with special radios and a vertical antenna that work with the HF band to take over communication once they leave the range of the VHF.

The pilot is responsible for all things that happen on the ground and in the air. However, because there are so many things to do and prepare, the pilot doesn’t do everything alone. He or she works with a team made up of cabin crew, cleaning crew, air traffic control (ATC), GSE mechanics, and so on. And in order to communicate and coordinate all these personnel, the pilot uses the most important tool in their arsenal, the portable aviation radio. 

There are many different uses for the portable aviation radio, from radioing for clearance to communicating with ATC for help during turbulence, the portable radio can be a life-saver. But that begs the question of “how good is a portable radio during emergencies?” Is it only good up to a short distance from the airfield? Or does its usefulness end with the boundaries of the airfield? 

The Icom A14, Icom A24, Yaesu FTA-550, and Sporty’s SP-400 were put to the test in a one-hour flight on a Robinson R44 helicopter. Most pilots would assume that portable radios only work within a few miles of the airport at best, but apparently, that’s wrong. Surprisingly, the portable radio is more useful than we’re inclined to believe. In fact, the portable radios were perfectly usable at a range of 5 miles from the airport. Even at 10 miles, all transmissions were still readable — that’s enough of a range for most emergency situations. At 10 to 20 miles, the results began to vary. The Yaesu was the most limited, becoming unreadable at 17 miles, while both Icoms worked up to 20 miles. The Sporty’s SP-400 worked very well up to 20 miles and only became unreadable at 25 miles.

With more people flying longer distances, airliners are competing by offering more amenities such as in-flight internet service. For a lot of airliners, that means finding the right service provider who will outfit and retrofit their fleet with the fastest broadband service, in the fastest installation time. It’s become a bit of a race between service providers. Airliners have massive fleets, generally a mix of older and new model planes, that all have to be fitted with broadband service. However, taking a plane out of service to get fitted incurs a loss; the longer it takes, the higher the lost. Knowing that the installation time can be crucial to an airliner’s decision, broadband providers are racing to reduce their installation times and even develop new and easier to install equipment.

At Gogo, their 2Ku installation time is consistently around 36 hours. Initially clocking in at 5 days, they were able to reduce down to 3 days, the current 36 hours, and occasionally down to 30 hours. With technicians becoming more efficient with each installation, Gogo has seen a lot of commercial success. At Inmarsat, the Ka-band satellite-based broadband service called the GX Aviation has an installation time averaging 4 days. They’ve recently launched a hybrid commercial Digital satellite and air-to-ground based EAN that cuts the installation in half at 2 days due to the newer and simpler technology.

Other companies like Phasor, ThinKom, and Panasonic are racing not to shave off their installation time, but to create and market a new connectivity system or antenna that is smaller, simpler, easier to install and maintain, and offers better broadband service. However, as Gregory Montevideo, senior director at Panasonic Avionics’ Global Communications Group, points out, current estimates on these new antennas are already 3-4 times the current cost of traditional antennas on the market, making it very difficult to market to airliners who already want to keep costs low.

Regardless of what kind of broadband service your airline of choice uses, you can trust that your connection is stable and strong for hours of inflight entertainment. Because, airliners and MROs know that if they need a replacement or spare part, they can come to us at Complete Sourcing Solutions, one of the premier suppliers of aviation components and electronic parts. Owned and operated by ASAP Semiconductor, we have everything from antenna parts to satellites.

Boeing aircraft has been the leader in passenger planes. However, Airbus, a rival of Boeings has inked a deal to produce the C Series jet designed by Bombardier in Mobile, Alabama. The plane is a bombardier design, used for commercial aviation for the U.S market. Canadian company Bombardier was trying to sell the aircraft for much lower prices than U.S companies could due to government allocated money for aerospace.  This government aid made it so they could sell the aircraft for less money drowning out U.S based companies. The U.S trade Commission ruled that this should not happen. Therefore, Bombardier had no leverage to make money off the Bombardier design and sold it to Boeing’s rival Airbus Industry. This is the reason for Airbuses takeover of the bombardier passenger airplane design for the U.S market. Starting with the acquisition of most of the Bombardier stock. The Airbus will be in stock for purchase into the U.S market by 2020 according to Airbus.

Airbus A321 Jetliner just broke the record for longest recorded flight in the world. The eleven-hour flight flew from the Seychelles islands to Toulouse France for a total of 4,750 nautical miles. Airbus group of industries has been training for the long flight for a while and finally accomplished the task at the end of March.  The test flight simulation was created to resemble a real flight as closely as possible. The simulation included 162 heat replicating human- dummy passengers and a 16-member crew. This type of simulation allowed for a more precise evaluation of how the real flight process would go and was practiced over 15 times to ensure the results didn’t vary.  The fuel consumption and aircraft reliability performed exactly as predicted, a situation that was clearly a huge accomplishment for Airbus.

With a third auxiliary fuel tank and a maximum take-off weight of up to 97 tonnes, Airbus designed the A321 with reliability and flight longevity in mind. This aircraft opens an entirely new market for trans-Atlantic travel, as it can accomplish longer flight times and cover more miles than previously designed aircraft. The A321 Jetliner also allows for a larger passenger capacity, fitting 240 passengers per flight.

Airbus is an international leader in the aviation and aerospace industry. They are constantly manufacturing, designing and delivering solutions, services, and solutions to customers around the globe. The company was based on a strong European heritage and has since grown to become truly international with over 180 locations and 12,000 direct suppliers across the globe.  The company has delivered over 10,926 aircraft and has achieved a six-fold order book increase in the last 18 years.  Airbus is the future of aircraft travel.

Earlier this year, Boeing made a huge announcement that rocked a few boats n the aviation industry. Boeing will expand their stock by beginning to produce aircraft seats of all kinds. Boeing is teaming up with the mega-company, Adient Aerospace in order to ensure that their seats are up to the strict industry standards. Because these two companies are pairing up the public can expect quicker service and a superior product. Aerospace has had a hard time perfecting the airline seat. Many complaints have been filed and the production of seats is long, slow and costly.

There have been many instances where the production of entire fleets of aircraft has been held up due to the seats either being faulty or not ready on time. There were also some rumors among professionals that upper management was putting key aircraft components importance, this could be items like the seats, cabin walls or lights, on the back end of production. By putting less importance on these parts, it slows down the whole building process and creates inferior products for the consumer.

Adient is a sister company of the Johnson Control Group, which handles automotive seat configurations. When Boeing decided to collaborate with Adient they brought in a whole new expertise for these key components.

The main factory for the new aircraft seats will be located in Kaiserslautern, Germany, where a lot of its subsidiaries are already headquartered. This means that all production will take place right beside one another, making the transition seamless.

Singapore Airlines has officially been given the rights to be the first airline service to have a fleet which contains all three of the optional models of Boeing Dreamliner’s. The addition of the new 787-10 Dreamliner, which will be introduced into the rotation later this year, marks the competition of the Dreamliner series.

The 787-10 is the latest and greatest airplane to hit the market. Its large size makes its fuel efficiency seem almost impossible, yet it easily surpasses other large planes in similar categories. There was a large celebration held at one of the Boeing campuses in North Charleston, South Carolina. The company was able to pack more than three thousand people into space and they celebrated the launch of the newest aircraft to hit the market.

Some new additions to this aircraft, that differ from similar models from the past, are the addition of new seats, which brings the internal cabin capacity up to three hundred and thirty. Even with the addition of all these new seats, this new Boeing 787-10 Dreamliner is the cheapest to run out of all the planes of the same body type throughout the entirety of aircraft history.

Singapore Airlines ordered sixty-eight new aircraft from Boeing to add to their fleet. A mix of 787-9, 787-8 and the latest and greatest 787-10 made up the order of sixty-eight. It should be interesting to see how Singapore Airlines chooses to use these planes in the future, and see if they put in an order for even more.
