Every month OAG updates its year-to-date Punctuality League table to provide an ongoing ranking of the world’s largest airlines and airports alongside its Monthly on-time performance (OTP) data. The list is based on the twenty largest airlines (by number of flights operated) known as Mega Airlines, and we provide a Top 10 ranking. With November Monthly OTPs now in, we have 11 months of data to take an early look at how these Mega Airlines have performed to date.
And whilst we have another month of data go, it is great to share some early insights before we release final numbers early next year.All the Top 10 airlines in our sneak preview currently come in with an OTP of over 85%. When compared to 2019, the last year of ‘normal’ flying, the Top 10 Mega airlines achieved OTP of between 75% and 86%, so this is a clear indication of just how much punctuality has improved over the past year.

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

While countries continue to implement new Omicron-related restrictions in response to the rising number of cases globally, a majority of these are in the form of enhanced COVID testing requirements – not travel bans. As a result, travel demand for popular peak-season destinations has remained strong, and over the past few days we’ve seen a BIG INFLUX in bookings as news trickles out that Omicron may be a less severe variant.
If this continues, we expect to see another prolonged booking surge, so plan accordingly and get your requests in ASAP for best options – especially parking and hotels. While the new U.S. 24-hr testing requirement for return travel is tight, it’s not a big deal if you are prepared with an approved at-home testing kit (like Abbott BinaxNow, Qured, Ellume, etc.). Alternatively, our Trip Support Teams can help you identify testing providers abroad.
Looking ahead to your missions in 2022, you may want to consider On-Aircraft COVID Testing for your N-registered aircraft. It’ll make international COVID testing MUCH easier on you and your passengers when at-home testing kits aren’t an option.

NASA is known for developing and launching spacecraft that have a significant environmental impact. However, the space agency is fully on board with the net-zero movement. NASA supports the White House's Aviation Climate Action Plan. It is helping fund several aviation projects that aim to reduce the aviation industry’s damage to the environment.
NASA’s Sustainable Flight Demonstrator Program
NASA focuses on technologies for single-aisle aircraft, which are the powerhouses of many airline fleets and account for nearly half of global aviation emissions. NASA's Sustainable Flight Demonstrator (SFD) project aims to reduce carbon emissions and keep the US competitive in the design of single-aisle commercial airliners, which are in high demand.
"Since its creation, NASA has worked with industry to develop and implement innovative aeronautics technology and has shared it with the world," said NASA Administrator Bill Nelson. "Now, with this ambitious new project, we're again joining with US industry to usher in a new era of cutting-edge improvements that will make the global aviation industry cleaner, quieter, and more sustainable."
NASA Wants to Reduce the Environmental Impact of Commercial Aircraft
The program’s goal is to build, test, and fly a large-scale demonstrator. NASA hopes to find a business partner for a Funded Space Act Agreement with its Armstrong Flight Research Center in Edwards, California, by the beginning of 2023.
The agreement would draw on private-industry knowledge and experience, with an awardee developing a suggested technical plan and committing considerable cash to the project. Under this agreement, NASA would not purchase an aircraft or any other hardware for its missions. The mission of NASA is to develop new and innovative technologies and capabilities.
NASA will collect data on the ground and in the air. Agency and industry teams can use it to test the airframe configuration and related technologies.
Moving Away From Space
NASA's technologies are typically cutting-edge. However, as with many high-end items, the benefits and applications frequently filter down to the masses. NASA's specialized technology and research frequently has civil aviation applications. It's interesting to see how NASA seems to be moving away from space and going after planes that fly closer to Earth.
