Commercial Aircraft and Cold Temperatures

When frigid temperatures hit the north-central and north-eastern United States earlier this year, hundreds of flights were grounded or canceled due to the extreme weather. And that can make you wonder, what exactly makes cold weather so difficult for commercial flight? Just a hint, the problem is not what it seems.

Generally speaking, you might think cold weather involves an array of problems for an aircraft. From frost formation to snow accumulation, it seems like a total disaster for commercial flight. We will get to frost and snow, but, overall, aircraft are actually more efficient in lower temperatures. A colder temperature means less humidity and denser air. As a result, the aircraft engine is able to utilize a larger quantity of air/fuel mixture than it would at warmer temperatures. This process gives the aircraft engine parts more horsepower and allows it to take off and land more quickly. Often, this creates a smoother flight-feel and more efficient operation overall.

Aircraft also have numerous redundancy measures to ensure it stays heated at a proper temperature, and to ensure that frost does not form on the airframe, even in extremely cold weather. Components that have specific temperature requirements, such as fuel oil, hydraulic fluid, and internal combustion units, will have integrated systems to keep them heated; this might include preheaters or aircraft engine analyzers. As long as the aircraft is preheated and an aircraft engine preheating process is followed, the aircraft will have no problem maintaining its required temperatures for flight.

It’s critical to ensure that frost does not form on the airframe top of an aircraft. Even a small amount of frost can change the pattern of airflow over the aircraft surface, increasing drag and causing a multitude of other challenges. Most commercial airliners use antifreeze fluid to ensure this does not happen. A coat of the glycol-based fluid at the gate will ensure that frost does not form on the aircraft surface before it reaches higher altitudes. The airframe itself is built to withstand temperatures of around -40 to -70 ? while flying altitudes upwards of 30,000 ft. Due to vapor pressure in the air (vapor pressure dictates the formation of ice) frost cannot form at these altitudes.

Here’s the main issue for commercial flight— while aircraft are engineered to survive volatile conditions, cold weather is much harder on airport operations. There are no preheating methods for a frosted tarmac, nor for frozen jet fuel equipment. Despite the likelihood of hundreds of aircraft needing anti-icing treatment and jet fuel, an airport cannot keep ground operations workers outside for longer than 15 to 20 minutes at a time in frigid weather. Any addition of snow complicates air traffic control visibility, and related operations even further.

And that’s the gist of cold weather and its effect on an aircraft. Though aircraft fly more efficiently at colder temperatures, extreme cold weather is a nightmare for airport operations.

Aircraft Engine Overhaul Process to Prevent Engine Failures

There's a strong tendency to compare aviation to the automotive industry. But, the list of similarities is short. Aircraft and automobiles couldn’t be any more different. For example, if a car engine breaks down in the middle of your commute, you can just pull over and call a tow truck or try to fix it yourself, but you can’t do that when an airplane’s engine fails. 

Aviation is all about safety, so it stands to reason that preventing aircraft engine failure is a multi-step process with many different checkpoints. The pilot performs a quick preflight inspection before every flight; the maintenance crew forms A, B, C, and D checks at specified intervals; all Aircraft Engine Parts and assemblies on the aircraft have set maintenance and repair inspection schedules; and after a certain number of manufacturer-specified flight hours, there’s the overhaul. It can be a frustrating process, so here are three things everyone should know about the engine overhaul.

The overhaul is a thorough inspection of the aircraft engine— the engine assembly is removed, disassembled, cleaned, inspected, repaired as necessary, tested according to OEM guidelines, reassembled, and reinstalled. It’s a very important process in maintaining the life of the engine and the aircraft as a whole. But there are actually two types of overhaul: top overhaul and major overhaul. The top overhaul is where the whole engine is not completely disassembled, only the parts outside of the base crankcase, such as all the cylinders and pistons. The major overhaul is when the entire engine assembly is disassembled and inspected.

It’s important that you only trust your aircraft engine overhaul with overhaul professionals. The whole point of an engine overhaul is to ensure airworthiness, that the aircraft is safe to fly. If the overhaul is done incorrectly or haphazardly, the risk of danger increases. Also, overhaul professionals are better connected to OEMs and aftermarket suppliers than the average smaller and unknown option, so they can not only conduct the overhaul properly, but they can probably do so more quickly and efficiently, ultimately saving you time and money. Overhauls are expensive as is, but utilizing a non-expert that does the overhaul incorrectly just means you either have to do redo it or you risk the loss of lives and property.

Another important thing to remember is to adhere to TBOs (time between overhauls). The TBO is the number of running or flight hours the aircraft engine’s OEM recommends between overhauls. Aircraft can’t be repaired on the side of the road when they break down the way a car does, so it’s best to stick to a strict TBO schedule and make sure that everything is taken care of before it becomes a problem. While the overhaul is a lengthy and expensive process, it’s worth it to know that you’re flying safe and sound.

aircraft alternator inspection

When we think of the things we need to fly, we usually think of the engine. Afterall, combustion is what powers the plane. So, it’s easy to fixate on the engine and neglect the alternator. But, without the alternator, we don’t have access to our digital nav/com radios, integrated GPS, multifunction flight displays, and so on.  

The reliability of your aircraft’s alternator relies heavily on routine maintenance and inspections.  Typically, inspections happen every 100 flight-hours, with a more thorough one every 500 flight-hours.  These inspections are important because they can warn you of any impending issues, ultimately preventing a blowout or loss of power.

When inspecting your alternator, you should begin with the alternator belt.  You’re looking to make sure the belt has proper tension and pulley alignment, and that it’s free of significant wear/damage.  Just like with your car’s tires, you can tell if the alignment is off based on the wear of the belt; Most of the wear should come from the sides of the V-portion because they do must of the work.  If the wear is misaligned, this could be an indicator that the pulleys are out of place or the mounts are shifting.

Next, inspect the actual alternator.  It should be somewhat clean and free of carbon dust; the presence of significant carbon dust may warrant a more significant internal inspection of your alternator.  All electrical wires should be fully secured and without abrasions— abrasions can lead to alternator failure (dead battery) and disconnected wires can lead to a failed direct current.

The battery directly supports the alternator, which is why it is so important to inspect all of the attached wires.  The battery’s diodes allow the alternator to convert alternating current into direct current. A dead battery can still function, but, if the battery is disconnected, it serves no purpose at all.  For these reasons, it’s vital to ensure that when you’re switching from one battery to another, the system should never be without power.

Fixed Wing or Rotary Wing?

From snow-capped mountains and forests of tall redwoods to scorching deserts and beautiful beaches, California is known for its beautiful and diverse landscapes. And while driving through them can be a fun experience, flying is truly the best way to see it all. But, once you’ve decided to travel by air, you’ve now got to choose how: fixed wing or rotary wing?

Fixed wing aircraft are airplanes, gliders, and other aircraft capable of flight based on the shape of their wings and the airflow over and under the wing. Fixed wings tend to be faster, capable of flying at higher altitudes, and for longer distances, making them more ideal for seeing better views in places that are farther apart. They’re also an affordable and safe way to see the sights because they don’t vibrate as much as rotary wings, so they can fly more smoothly and linearly, decreasing the chances of motion or airsickness. Also, because fixed wings are able to fly faster and for longer distances at lower operating costs, they generally give you more bang for your buck.

Rotary wings are helicopters and other such aircraft that fly with rotating blades. They’re a new and exciting way to see new sights because they’re versatile. You can land in excluded and exotic locations more easily in a rotary wing than a fixed wing. And, because helicopters can hover, they can fly through turbulence when a fixed wing would be grounded. While rotary wings are generally the more tumultuous method of flying and therefore not a great idea for those prone to motion sickness, advancements in rotary wing technology have decreased vibrations and excess noise, leveling the comfort difference between fixed wing and rotary wing.

Ultimately, it’s up to you to decide how you want to fly. There are pros and cons to each, and researching your options is the best way to go. But, whatever you decide, rest assured that ASAP Buying has your back.

ASAP Buying, owned and operated by ASAP Semiconductor, is a leading supplier of new and obsolete and hard-to-find parts and components for the aerospace and aviation industries.

Fixed-wing Aircraft or Rotary Wing Aircraft

In recent years, there’s been an increase in flight and aviation across the board. People are flying more than ever. They’re also owning their own private aircraft more than ever. But before purchasing, it’s important to understand what kind of aircraft to choose. A fixed-wing or a rotary wing? What’s the difference? Well, the biggest difference is in the way they can fly.

A fixed-wing aircraft is generally an airplane. It can also be a paraglider or a hang glider, as these also have immobile wings that use forward airspeed to generate lift. In powered fixed-wing aircraft, the thrust from the propeller or a jet engine is what moves the aircraft. Because fixed-wing aircraft require air moving over their wings to generate lift and be airborne, they are must stay in a constant forward motion and cannot hover stationary.

A rotary wing aircraft is typically a helicopter, autogyro, or any other aircraft with rotary wings, or rotor blades. Rotary wing aircraft use these rotary wings to revolve around a rotor to lift the aircraft and maintain flight. As opposed to fixed-wing aircraft, rotary wing aircraft do not need constant airflow over the blades and rely on constant movement of the rotary wings to generate the required airflow over their airfoil to generate lift. They do not need to stay in constant forward motion and can hover stationary.

Other than these major differences, a fixed-wing and a rotary wing aircraft do not differ all the much. The same principles govern the physics and motion of both. Ultimately, choosing between the two comes down to personal preference. What do you want out of an aircraft? If you want to relax a bit more during flight, an airplane might suit your tastes a bit better. Of course, choosing between the two doesn’t mean that you’re only ever limited to one or the other. If you’re enthusiastic about flying, you’ll want to own and fly both. You’ll also want to maintain both.

Other than choosing which aircraft to buy and fly, it’s important to be able to repair and maintain your aircraft and know what you need. Fortunately, there’s us at ASAP Buying. Owned and operated by ASAP Semiconductor, we’re a leading supplier of all aviation parts and we’d be delighted to help you find the aviation parts you need.

 jet engines work

Have you ever looked up and noticed those long, white streaks across the blue sky? Those are vapor trails caused by jet engines. Jet engines burn fuel using the air, releasing energy and powering the plane; this is a process called combustion. These engines are sometimes referred to as gas turbines because they bring fuel in through a windmill-like wheel, also known as a turbine, and expel hot gas.

Jet engines are similar to car engines in that they both burn fuel to release energy that powers them. There are three specific things that allow a jet engine to be more powerful than your car’s engine though:

  1. The law of conservation of energy – If a jet engine needs to make more power, it needs to burn more fuel. Jet engines are designed to burn large amounts of fuel by pulling in massive amounts of air (the ratio is about 50 to 1).
  2. Jet engines are always in maximum power mode because the intake, compression, combustion and exhaust all work synchronously.
  3. Jet engines pass the exhaust through multiple turbine stages, extracting the maximum amount of energy (piston engines only use one).

All jet engines work in the same fashion (pulling air in, combusting with fuel, and expelling exhaust) however there are six different types based on their featured components:

  1. Turbojet –good for small, low-speed jets
  2. Turboshaft –exhaust gas produces little thrust; found in helicopters, trains, boats and tanks
  3. Turbofan (low-bypass)
  4. Turbofan (high-bypass)
  5. Ramjet/Scramjet –ramjets are suitable for supersonic and hypersonic speeds (used on rocket and missile engines); scramjets can go even faster because they remain supersonic
  6. Turboprop –most of thrust comes from propellers, which are mounted on the front and push the plane upward

parts of Aircraft

Listed below are quick over views of 6 key components of a modern aircraft. The components mentioned in this article will be the wings, empennage, powerplant, landing gear, aircraft frame and fuselage. All of which are extremely important in making sure that the aircraft flies properly.


As most people know, the wings are the key component in keeping any aircraft airborne. They provide a place for lift that propels the plane upwards. Wings can be fashioned to the side of the plane in multiple areas, either high up or a bit lower down on the body. At the base of each wing is a small section that can be controlled by the pilot, called the flaps. These flaps can be moved and positioned in flight, takeoff and landing.


This is the main body of the aircraft where you would sit when flying in a plane.


This section of the plane, as the name would suggest, houses the components of the plane that power it. This is where the engine lives.

Aircraft Frame

The frame, or base, of an airplane can be made of several different things, each with their own perks and benefits. Some frames allow for more pressure to be applied, some are extremely aerodynamic and others offer the builder extra support.


This not only holds the plane steady but also allows the pilot to steer and direct the plane from the cockpit by controlling parts of the empennage such as the rudders.

Landing Gear

This aspect of the plane can differ quite a bit plane to plane. While on one aircraft the landing gear could be referring to wheels, on another the landing gear could be made up of long ski’s to allow the plane to instead land on water.

An aircraft propeller

An aircraft propeller is more complex than an individual would think. Surprisingly, propellers do not exist solely to move aircrafts, they have outside uses. There are several different types of aircraft propellers all varying in design and material. This article will discuss the similarities and differences between all the different propellers the world has to offer.

First, we will review Fixed Pitch Propellers. Fixed Pitch Propellers are made solely from one piece of material; therefore, the blade pitch cannot be changed. Fixed pitch propellers are typically made from either metal or wood. Wooden propellers were mainly used for every single aircraft made before world war two. Although the wooden propellers look as though they are carved from one piece of wood, they are composed of 5 different pieces of wood laminated together. Wooden propellers are not as popular as they once were because the world has shifted towards metal propellers. Metal propellers were created many years ago and were originally used for military application. In the modern world, metal propellers are they primary choice for most aircrafts. Metal propellers are made from a single piece of aluminum alloy and therefore, have the ability and strength to last longer.

Ground Adjustable Propellers are the second class of propellers we will review. This type of propeller is ground adjustable meaning, the blade pitches can be fine-tuned and switched out with ease. This type of propeller can compensate for all different types of weather conditions and is safe for different flight altitudes. These propellers are most common on commercial aircrafts. Other important propellers include: controllable pitch, constant speed, two positions, reversing and full feathering. Each propeller has a different specialty making each choice highly specific.

ASAP Buying has a dedicated and expansive array of fixed pitch, ground adjustable and constant speed propellers, making us the premier supplier of aircraft propeller components. We serve customers as a one-stop shop and primary destination for product sourcing. ASAP Buying will ensure that your needs are addressed in the most expeditious and transparent manner, all the while offering cost-effective component solutions.

Key Considerations for Selecting Aircraft Parts

In recent times, it is not very common to hear about Original Equipment Manufacturers (OEM) producing doubts over aircraft parts safety produced by companies complying to a FAA-issued Parts Manufacturing Approval (PMA). In the past, there was a time when OEMs looked down on PMA parts produced to compete with their products. Their comments usually focused on safety claims and abuse of OEM warranties.

Due to the request made by OEMs, the FAA and EASA went through a lengthy investigation into these safety claims in 2008. The investigation revealed that there was no evidence of PMA parts being unsafe and the investigation concluded that there were no issues with their process of approving PMA parts.

Many individuals do not understand the difference between OEM and PMA, and what makes a part “approved.” If a part is approved, this means the FAA has given a specific type of approval, whether it is for an individual item or as a part for an engine, etc. Parts in aircrafts, engines and avionics need to meet the standards of the FAA that are specific to the role of the part.

An OEM holds a “Type Certificate (TC),” and TC holders can manufacture parts under the certificate. The parts that are manufactured need to be shown, labeled and documented to meet the standards of the approval. By holding a Type Certificate, the OEM has proven that the parts work safely for the higher end product they have been produced for.

PMA parts can be produced by any individual or company that chooses to go under the process of designing and documenting an OEM part’s equivalent. There is am important process a business or person must undertake for the PMA part to be approved. First, they need to submit the design for the PMA part to the FAA to make sure it is sage and meets the requirements of regulation. Second, the hopeful PMA supplier needs to pass an FAA review of quality assurance to make sure a quality assurance system is in place and to verify the part manufactured falls under FAA design approval.

ASAP Buying, which is owned and operated by ASAP Semiconductor, is a leader in the procurement of aircraft parts, NSN parts and more. As an aircraft component supplier, ASAP Buying can source more than 30 million parts from over 5,000 manufacturers.
