When operating aircraft above the Arctic Circle (66.5° N latitude) there are certain hazards to be aware of. We decided to take a look at what aircraft are best suited for Arctic flight.A huge problem with flying in the Arctic is not just icing, but the visual restrictions that are placed on pilots. During the spring and fall, whiteout or flat light can distort what a pilot sees. The horizon can suddenly disappear making objects appear as if they are floating in the air. This can make things like mountain ranges extremely difficult to judge.

Can the aviation industry have a net zero-carbon emissions? Can technology assist in achieving net-zero emissions?
Presently, customers are taking more flights than ever as the industry is set to grow post-pandemic effects. Data from IATA shows that the UK aviation industry alone ejected thirty-seven million tonnes of CO2 into the atmosphere in 2020. That’s an average of 9% more in tonnes of emission the industry recorded in 2018.
The warnings are transparent. In the latest reports of Intergovernmental Panel on Climate Change (IPCC), the effects of global warming are escalating.
“We know the challenges of climate change the world is facing. It has only continued to intensify,”
-Nicholas Calio, president and CEO of Airlines for America
Airlines are subsequently embracing their actions towards the recovery of their business. There is a need to take even braver, more momentous steps to address this challenge.
Airlines have been focused on carbon offset programs for years. It has previously invested in projects and organizations that assist in reducing the impact of CO2 emissions.
In March 2021, the U.S. airline industry announced that its market leaders are committed to achieving zero carbon emissions by 2050.
The aviation industry is currently rising at between 4% and 5% a year. And the number of passengers will double every 15-20 years. How will the industry let fly with zero emissions? Certain plans strongly focus on the increasing use of sustainable aviation fuel and jet fuel. These fuels are produced from sources such as plant oils, municipal waste, agricultural residue, fossil fuels, and other interim steps.
The blog accumulates some of the best ways that aviation has unveiled on the grounds of zero carbon emissions.
Escalating the Use of Alternative Fuel
The escalating use of alternative fuels is perhaps the most significant proposed carbon reduction initiative for sustainable aviation fuel (SAF) usage. Sustainable fuel is going to be created from plant or animal material. One of the examples is waste oil.
It is studied that SAF has the potential to cut life-cycle emissions from aviation by 80%. It can be blended with conventional jet fuel without making major changes in aircraft designs. But, as technology is concerned with SAF usage, it can be eight times more expensive than conventional jet fuel. SAF currently values less than 0.1% of the almost 300 million tonnes of fuel that commercial airlines use every day.
some companies are taking regulatory incentives in joint efforts with aviation after looking at the costs and ensuring that more SAF is used in the future. Let’s see which corporate companies are setting commendable aviation-related commitments.
Microsoft partnered with Alaska Airlines. Together, they are working to cover CO2 emissions to make their employees’ travel safe by introducing SAF credits.
FedEx has committed to purchase 13 million liters of sustainable aviation fuel from Red Rock Biofuel. It is a part of their long-term net-zero emission strategy.
Express GBT created an alliance to help in increasing supply SAF to under carbon reduction initiative and become zero carbon-emitting by 2050.
Industry-Wide Efforts
The path to climate recovery with zero airline emissions will require a collective effort from all industries. This also includes governments. They must take responsibility for the impact of certain activities, products, and policies have on the environment. The production of fossil fuels is one of them. So, the aviation industry must reduce its dependency on fossil fuels for air travel.
Industries such as energy, road transport, infrastructure, manufacturing, and finance are being collectively responsible for creating a risk-free airline emission. For example, policies of energy transition must include a change in the production plan. Road transport efforts should be advanced by designing electric vehicles. Manufacturers should bring in new technology to support the creation of lightweight engines and aircraft parts. All of them should join hands for a sustainable future for aviation.
The Role of Government Investments
Government bodies play a crucial role in heading up carbon reduction initiatives. The initiative will have solutions such as new aircraft technology and more efficient infrastructure and operations. It also includes the development of zero-carbon energy sources like hydrogen and electric power generation.
According to IATA, 1.8 gigatons of carbon will be required to sustain the aviation industry in 2050. The prediction can achieve 65% of carbon for sustainable aviation fuels.
What are other solutions in demand to commit to addressing a zero-emission environment? It includes:
Fuel-producing companies are to bring large-scale, cost-competitive sustainable aviation fuels (SAF) to the market.
Governments and air navigation service providers (ANSPs) eliminate inadequacies in air traffic management and airspace infrastructure.
Aircraft and engine manufacturers produce more efficient aircraft engines and propulsion technologies.
Airport operators provide the required infrastructure to supply cost-effective SAF.
Airline Firms Decarbonizing Aviation
Presently, aviation is driving towards a new chapter of growth. And the pillars of growth are the firms that are continuously making efforts to make aviation a risk-free industry.
Let’s see how aviation firms are contributing to making a zero-carbon emission sky for safe air travel for the future.
Delta Airlines
Delta and Aviation Climate Taskforce are initiating technological innovation and accelerating the research and development of emerging technologies. Emerging technologies refer to reducing CO2 footprint production. They are focusing on their approach towards medium-term solutions, near-term solutions and long terms solutions.
The mid-term solutions include synthetic fuel. The near-term solutions focus on emerging bio-based Sustainable Aviation Fuel (SAF) pathways. And long-term solutions include hydrogen technologies. ACT will aim to support the advancement of these technologies through two crucial pillars:
An Innovation Network
A Collaboration Forum
JetBlue
JetBlue went carbon neutral for all its flights. It went through carbon offset programs in partnership with the CarbonFund.org Foundation. The investment included solar, wind, and hydrogen-energy project initiatives.
Apart from this, JetBlue also invested in hundreds of global carbon offset programs to support renewable energy efforts.
“views carbon initiative as a platform for other industry-wide environmental improvements that support lower emissions.”
-JetBlue
The best part is that JetBlue also invested in sustainable aviation fuel on flights. They are currently operating from San Francisco International Airport.
American Airlines
American Airlines changed its strategy of using traditional jet fuel. The airline has committed to purchase 9 million gallons of SAF to lower CO2 emissions in the next three years.
Southwest Airlines
On Earth Day 2021, Southwest Airlines announced it would continue to support the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). NREL works to develop cost-effective low-carbon aviation fuels that are generated from waste.
The airline SAF will play a vital role in getting the atmosphere carbon neutral and will be able to achieve carbon neutrality by 2050. On this, NREL estimates that wet waste typically produces enough energy to provide about 20% of jet fuel consumption.

Airplane travel is one of the most convenient means of transportation. Consequently, air travel is growing, and aircraft need to be more efficient. Furthermore, in the aftermath of the pandemic, the aviation industry appears to be committed to ensuring a sustainable airflight future. So, for this, aircraft need to be more efficient in production costs and fuel consumption.
An aircraft design depends on three of the most critical aspects. The first is the factor of reliability. Aviation is the only industry where it is impossible to overlook, rectify, or investigate a failed flight mechanism on the spot. The second factor is the need to minimize the weight and volume of its components to withstand load and fluctuating temperatures. And, the third factor is that it shows extreme concern from an environmental perspective. Temperatures on the ground can reach 60 °C and even -80 °C in the stratosphere, with supersonic aircraft reaching temperatures of over 200 °C.
As a result of these factors, the aircraft lubrication system and its requirements are critical. From an economic perspective, servicing and maintenance are a significant part of airlines' expenses after the purchase. In addition, the replacement of parts can cause airplanes to remain grounded for an extended period. Such circumstances can lead to a loss of time and money simultaneously.
From a safety aspect, failures at every level should be avoided. Failures like the shutdown of engines or breakage of engine parts can lead to aircraft failures or even crashes. So, by knowing all these issues around air travel, you can easily understand the interest in aircraft engine oil.
An Innovative Lubrication System for Aircraft Engine
Aircraft turbines revolve at up to 18,000 rpm (revolutions per minute). Due to this, internal temperatures can rise compared to the ambient temperature outside. So, aviation engines need an efficient oil-based lubricant to less pollute the environment and sustain long-distance air travel.
Recently, researchers in the EU-funded ELUBSYS project developed a novel way to use specified aircraft engine oil to promote efficiency and reliability. For this, SAF (Sustainable Aviation Fuel) is in high demand. Moreover, the project's innovative oil production will also help reduce an airline’s operating and maintenance costs. In this way, Europe’s aircraft manufacturers are way ahead in supporting future aircraft engine development.
“Aircraft engine turbines rotate at a very high speed with the help of the classic rubberized oil-seals used in the aircraft engine. The extremes of temperature and friction involved would destroy them. Yet aircraft engines need to stay lubricated.”
-Vincent Thomas of Techspace Aero in Belgium
Apart from this, the piston engine looks promising for the aviation piston engine industry. However, it seems like a piston engine holds an optimistic future in fuel economy. Now, with the inclusion of piston engines, there is more importance to using piston engine oil in the lubrication system for an aircraft engine.
So, how piston engine will be the game-changer for aircraft?
Piston Engine—A Game-Changer in Fuel Economy
Numerous aviation firms are developing a new type of internal combustion engine. Such engines promise a notable boost in fuel economy while also plummeting greenhouse gas emissions. In addition, start-ups like EcoMotors, Achates Power, and Pinnacle Engines are building variations on piston engines with the help of specific piston engine oil.
The engines serve as combustion chambers where fuel is ignited. That makes engines lighter in weight and faster in their operations with greater power density. In this way, piston engines result in less energy waste and thus operate more efficiently.
“The technology is worthwhile. However, it is a completely different concept compared to conventional engines,”
- Dean Tomazic, Vice President of FEV in Auburn.
There are more success stories from the aviation piston engine industry. These stories predict that, indeed, aviation is going through a significant transformation.
Another significant achievement comes from Pinnacle, based in San Carlos, Calif. It is developing a four-stroke, gasoline opposed-piston engine. The company’s founder, Monty Cleeves, invented a sleeve valve that ensures energy is used for propulsion instead of getting wasted after converting into heat.
Functions of the Lubrication System for Aircraft Engine Oils
What are the significant functions of lubricants in aviation oils and engines?
It is the function that realizes the importance of things. Isn’t it? So, to realize the importance of aircraft engine oils, it’s crucial to show the potential of the aircraft lubrication systems.
1 Friction and Wear Reduction
Lubricants reduce friction and wear in an aviation engine. The aircraft lubrication system deals with cooling, sealing, clearing, and fighting corrosion and rust in the engine.
Airplanes that are used seldom need the thorough protection from rust and corrosion that good aviation oils can provide. Also, frequently flying airplanes need lubricants for smooth engine operations and functions to avoid failures.
2 Acts as a Cooling Agent
But it is critical to use good aviation oils as lubricants. Oil is a heat-transform medium. Thus, a suitable oil should be used so that lubricants can keep the engine cool and smooth.
3 A life Saver of Aircraft Engines
Lubricants help in extending the life span of an aircraft engine. If an aircraft uses good aviation oil, for example, SAF, biofuels, and more, then there are fewer chances of any engine repairs. In this case, piston engines are the best fit for aircraft with high demand. Piston engines use highly lubricant piston engine oils, which increase the longevity of aviation engines.
Let’s look at some key takeaways from the market study of aircraft engine oil.
Aircraft Engine Oil: Key Takeaways from its Market Study
Commercial planes and business jets will likely witness high aircraft lubricant oil sales.
According to IATA, mineral oil demand is expected to rise by 25% by 2030.
Bio-based oils will dominate the aviation industry in response to soaring environmental concerns.
Maintenance, repair, and operations (MRO) activities will emerge as crucial parts of aviation to drive the global aviation lubricant market.
Lastly, what’s understood is that aircraft engine oil is the engine's lifeblood. Thus, the engine must function efficiently to encompass the length between overhauls.
Frequently Asked Questions
What does engine oil do in an aircraft?
Engine oil functions as a coolant. Up to 40% of an aircraft’s cooling comes from engine oil. Oil creates a seal between the piston rings, which reduces wear and friction andprovides better compression with increased fuel efficiency.
How is the engine oil lubricated?
Engine oil is lubricated with seals using air, which holds back the oil. Air and oil need to be separated. The air eventually vents out in the form of heat. That is why good oil is necessary for aircraft for lubrication.
What are the essential functions of engine oil?
The essential functions of engine oil are:
Minimizes friction and reduce wear
Cleans the engine
Transfers heat
Prevents corrosion
Forms a seal
Cools the engine parts
