Directorate General of Civil Aviation (DGCA) has granted permission to IndiGo to operate its flight services to Nairobi in Kenya from July 24, a DGCA official said on June 13. This would be the airline's foray into the vast African region. The regulator, before permitting air carriers to start operations to new foreign destinations, assesses their preparedness to conduct such flights. After the assessment, DGCA approved the new flight service.

IndiGo had in February this year announced its plans to launch air services to Nairobi, Jakarta and some Central Asian countries as part of its international expansion plans amid increasing competition due to a rejuvenated Air India under Tata Group.

"IndiGo operations to Nairobi with effect from July 24 has been approved today (Tuesday)," the official said. Early this month, the airline said it will connect Nairobi in Kenya and Jakarta in Indonesia, with direct flights from Mumbai in late July or early August. Delhi will get connected in August to Tbilisi, Georgia and Baku, Azerbaijan and in September to Tashkent, Uzbekistan, and Almaty, Kazakhstan.

International Expansion in Cards

It has also said at that time that once these routes are operational, the airline will be connecting a total of 32 international destinations compared to 26 currently. IndiGo had said it will add 174 weekly international flights between June and September, including new destinations, routes, and frequencies.

The airline has also been expanding its international footprint via codeshare agreements. Last week, IndiGo said it will launch new codeshare connections via Istanbul to the US cities of New York, Boston, Chicago, and Washington, from June 15.

At present, IndiGo operates a daily two-way service on the Delhi-Istanbul and Mumbai-Istanbul routes. It has deployed one wide-body- Boeing 777 aircraft each on these routes. Through its codeshare arrangement with Turkish Airlines, IndiGo has been adding connections to European destinations over the last few months. These codeshare connections provide access to countries including Bulgaria, Spain, the Netherlands, Greece, Belgium, and Hungary amongst others.

Possible New Aircraft Order

Airbus is closing towards a potentially record deal to sell 500 narrow-body A320-family jets to India's largest carrier IndiGo, Reuters reported recently citing sources. The European planemaker has emerged as the front-runner for an order eclipsing Air India's historic provisional purchase of 470 jets in February, the sources said on the sidelines of an airline industry meeting in Istanbul. IndiGo, the country's largest airline with a domestic market share of more than 57%, has a fleet of over 300 planes and operates more than 1,800 daily flights.

Such a deal would be worth some USD 50 billion at the most recently published Airbus list prices, but would typically be worth less than half this after widespread airline industry discounts for bulk deals, according to aircraft analysts. They said that Airbus and Boeing are also competing in separate talks to sell 25 A330neo or Boeing 787 wide-body jets to the same airline.

Airbus and Boeing have been racking up billions of dollars of new orders stretching beyond 2030 as airlines lock in supplies well ahead amid looming shortages. Indian carriers now have the second-largest order book, with over 6% share of the industry backlog, behind only the United States, according to a June 1 report by Barclays.

The bullish outlook by IndiGo comes as the world's third-largest aviation market is seeing a strong rebound in travel post-Covid, with domestic and international passenger numbers surging despite high fares. IndiGo aims to double its capacity by the end of the decade and expand its network, especially in international markets.

How does Aircraft Paint Affect its Operating Cost?

Abhishek Nayar

14 Jun 2023

There are various aspects to consider when it comes to aircraft maintenance. One element that is sometimes disregarded is the effect of aircraft paint on operational costs. Aircraft paint serves more than merely an aesthetic purpose; it also plays an important part in an aircraft's overall performance and longevity. The type, quality, and condition of the paint can significantly influence various factors such as fuel efficiency, maintenance costs, resale value, weight, and overall performance.

Commercial airliners were (and still are) painted with the national flags or insignia of their different countries. However, with the rise of competing low-cost carriers in the commercial air travel industry, aircraft fuselages have been turned into enormous flying advertising billboards painted with eye-catching graphics or logos of your favorite beverage or sports drink, credit card firm, or cartoon characters.

Importance of Aircraft Paint

Aircraft paint serves multiple purposes beyond giving the aircraft an attractive appearance. It acts as a protective layer, shielding the aircraft's exterior from environmental factors such as UV radiation, moisture, and corrosion. Additionally, it helps streamline the airflow over the aircraft's surface, reducing drag and improving overall aerodynamics. Therefore, the choice of aircraft paint goes beyond aesthetics and directly impacts the aircraft's performance and efficiency.

The Factors That Influence Aircraft Paint Selection

When choosing the right paint for an aeroplane, several things must be considered. These factors include the operating environment, intended paint lifespan, color scheme, regulatory requirements, and financial constraints. Aircraft operating in coastal locations may require improved corrosion protection, whilst aircraft operating in harsh temperatures may require paint that can tolerate thermal stresses. Furthermore, airlines may use color schemes that are consistent with their brand identification.

Painting an Aircraft: Is it Necessary?

Although some aviation enthusiasts may argue that painting an aircraft adds tons of weight to a machine whose components are designed to shed every unwanted gram for greater fuel efficiency (the paint on an Airbus A380 weighs an estimated 1,103.31 pounds or 500 kg), planes benefit more from having a layer of paint because, without it, the fuselage, wing, and other exterior parts (metal or carbon composites) can be damaged relatively quickly during daily flight operations.

What is the Purpose of Aircraft Painting?

Aside from aesthetics, aircraft painting has multiple purposes. Let us delve into the key reasons why painting a plane is considered necessary.

Anti-Corrosion Protection

One of the main reasons for painting an aircraft is to prevent corrosion. Because aircraft fly in a variety of weather conditions and are exposed to external substances such as moisture, salt, and pollutants, the painted surface serves as protection. Corrosion can affect the plane's structural integrity, posing potential safety hazards. By applying a protective layer of paint, the aircraft's metal surfaces are safeguarded against the corrosive elements.

Performance and Aerodynamics

The aerodynamics and overall performance of a plane may be greatly impacted by painting it. The paint's smooth surface decreases the roughness generated by exposed metal surfaces. This reduction in surface roughness serves to reduce drag, allowing the aircraft to travel faster while utilizing less fuel in the process. The streamlined design facilitated by painting contributes to improved flight performance.

Safety and Visibility

Aircraft painting is critical to ensuring visibility and safety. The use of distinguishing colors, markings, and logos on the plane's exterior surface assists in identification and recognition. This is especially crucial when it comes to air traffic control, ground operations, and emergency circumstances. Furthermore, the hue of the paint can affect the reflectance of sunlight, reducing heat absorption and lowering the danger of temperature-related issues during flight.

Branding and Marketing

The painting of an aeroplane provides an excellent opportunity for branding and marketing. Airlines often customize their jets with distinctive liveries, logos, and designs in order to promote their corporate identity and establish a memorable visual presence. This distinctive aesthetic has the potential to create a lasting impression on passengers, increasing brand awareness and helping the airline's marketing efforts.

Compliance with Aviation Regulations

For safety and operational concerns, aviation authorities have created standards surrounding aircraft painting. These standards detail particular criteria such as emergency exit visibility, color schemes for different aircraft types, and reflective materials for enhanced visibility during low-light conditions. Aircraft operators guarantee that their planes satisfy the appropriate safety requirements by adhering to these regulations.

How do Planes Get their Paint Jobs?

Painting an aircraft entails applying multiple thin coats of paint to the fuselage, which requires specialized painting skills as well as modern low-pressure, high-volume painting HVLP equipment intended to minimize the volume of each paint layer. If the plane already has a coat of paint on it, it may be necessary to remove it. Each plane's paint job normally comprises three coats of paint: primer, base coat, and top coat, which gives the plane its glossy appearance. Planes with unique liveries or complicated designs may necessitate the employment of paintbrushes by artists. Modern painting techniques necessitate the assistance of 3D computer graphics to produce intricate artwork and predict how the final paint job will appear on the aeroplane.

Surface Preparation: A Clean Canvas

The surface of the aeroplane must be thoroughly prepared before any paint can be applied. This procedure involves the removal of old paint, grime, and pollutants. Technicians thoroughly clean and sand the surfaces to produce a smooth and homogeneous substrate on which the paint coats may adhere. A professional mechanic inspects the plane's exterior for damage, looking for cracks in the material, loose rivets, and dents. These are fixed and numbered in a "Buckle and Dent" report that documents all of the plane's repairs. On the plane itself, the numbered repairs are inscribed. Workers move the plane inside the paint shop while wearing protective gear, including a safety harness. The sanding or peeling of old paint on the plane begins. Boeing and Airbus planes have been partially sanded and stripped. Spraying a liquid solvent that dissolves all the paint in 24 hours at temperatures of 25°C is the most effective and environmentally benign method of peeling paint.

Priming: Laying the Groundwork

Priming is an important phase in the painting of an aeroplane. To increase paint adherence and provide an extra layer of protection, a coat of primer is applied to the prepared surfaces. The primer also helps to expose any flaws that must be corrected before proceeding with the paint application.

Masking and Stenciling: Precision and Detail

Masking and stenciling are crucial techniques for creating accurate drawings and marks on the exterior of an aircraft. To avoid overspray, highly competent painters meticulously mask off specified areas, such as windows and doors. Stencils are used to accurately produce logos, registration numbers, and other intricate details.

Base Coat Application: Colors in the Sky

The base coat application is where the airplane starts to come to life with color. Using specialized spray guns or electrostatic procedures, high-quality, aviation-grade paint is applied. Paint is applied in stages, with each coat drying before applying the next. This procedure ensures that the color is consistent and vibrant enough to endure the demanding conditions of flight.

Logo and Graphics: Branding the Aircraft

The identity and branding of an aircraft are frequently reflected by distinctive logos, airline liveries, and graphics. Skilled painters precisely recreate these motifs on the exterior of the aircraft, paying special attention to detail and ensuring brand consistency. The logos and images are precisely matched and applied, giving each plane its own visual character.

Clear Coating: Shielding and Enhancing

A clear coat is sprayed on the aircraft's surface after the base coat and graphics have been completed. This protective layer serves as a barrier, protecting the paint from UV radiation, chemicals, and environmental variables. The clear coat also improves the plane's glossiness and general look, giving it a polished and professional image.

Quality Control: Striving for Perfection

Before an aircraft is certified for service, it must pass stringent quality control inspections. Experts inspect the paintwork to ensure there are no imperfections, unevenness, or color variations. They also check for proper adhesion, stencil and logo clarity, and overall uniformity. To obtain a faultless and aesthetically attractive aeroplane, any necessary touch-ups or corrections are made.

How Much Does Painting a Plane Cost?

As you may expect, the cost of painting an aeroplane varies depending on the type, size, quality, and intricacy of the paint scheme. A single-piston engine plane paint job should cost between $5,000 and $15,000 USD. Painting a narrow-body passenger aircraft like the Airbus A320 can cost roughly $50,000, while painting a wide-body commercial aircraft like the Boeing 747 Jumbo can cost as much as $300,000, depending on the complexity of the paint job. According to a Wall Street Journal article, the cost of repainting a Boeing 777 is between $100,000 and $200,000. The 2020 repaint of the RAF Voyager UK's government VIP transport aircraft, which cost roughly £900,000 ($1.2 million) with taxpayer funding, is an especially egregious illustration of the absurd expenditures of painting an aircraft.

What is the Average Time it Takes to Paint an Airplane?

Painting a Boeing 737 airliner and other similarly sized aircraft takes around a week, whereas painting an Airbus A380 might take up to two weeks. Painting smaller planes, such as light sports aircraft and leisure planes, can take anywhere from 12 hours to several days, depending on the complexity of the painting scheme. According to a BBC documentary on how planes are painted, it takes around 950 person-hours for a 10-person crew to repaint an Airbus A319 aircraft.

The Impact of Aircraft Paint on Operating Costs

Fuel Efficiency

The smoothness of the aircraft's surface influences fuel economy. A rough or damaged paint surface can cause turbulence and drag, leading to increased fuel consumption. High-quality, well-maintained paint reduces surface defects and promotes laminar airflow, which reduces drag and improves fuel economy. This, in turn, leads to cost savings in terms of fuel usage during the aircraft's lifetime.

Maintenance and Repairs

The type of aircraft paint used can have an influence on maintenance and repair expenses. Paint systems with excellent adhesion and durability necessitate fewer touch-ups and repainting, lowering labor and material costs. Furthermore, certain varieties of paint are simpler to clean, making upkeep more efficient. By choosing the correct paint, aircraft operators may reduce the amount of time and resources required for maintenance, cutting operating expenses.

Resale Value

A well-maintained and aesthetically pleasing paint job may considerably increase an aircraft's resale value. Prospective purchasers are more likely to be drawn to an aircraft with a flawless paint finish, which indicates that the aircraft has been carefully maintained. This improved market attractiveness may lead to a better resale value, allowing aircraft owners to recoup a greater amount of their initial investment.

Weight and Performance

The weight of the paint used on an aeroplane can affect its performance. Excessive paint layers or the use of heavy paint formulas can add unnecessary weight to the aircraft, reducing fuel economy and overall performance. It is critical to select lightweight paint solutions that do not sacrifice durability or aesthetics in order to achieve maximum performance while minimizing operating expenses. According to Boeing, an average Boeing 737 requires around 189 liters of paint to be painted. Depending on the paint scheme, each aeroplane weighs roughly 113 kilograms when dry. In 2017, 360-450 kg of paint were required to paint the body of the Boeing 787 Dreamliner. However, if the aircraft is not completely painted, the cost of repairing it climbs by more than $130,000 per year when compared to the fully painted variant (again, according to Boeing statistics from the early 2000s).

Choosing the Ideal Aircraft Paint

Choosing the right aircraft paint necessitates careful evaluation of the previously listed aspects. Consultation with paint manufacturers, industry experts, and regulatory agencies can provide vital information on the best paint alternatives for specific aircraft and operating requirements. Cost-benefit calculations, long-term durability evaluations, and environmental impact assessments of paint options are all critical phases in the decision-making process.

What is the Best Paint for Aeroplanes?

Aircraft operate under extreme conditions, and the paint used on exterior surfaces must endure intense temperature fluctuations without premature fading, peeling, or breaking. The two distinct substances utilized for producing aircraft paints are epoxy and enamel. Both compounds have high adhesion and hardness properties, making them appropriate for use in aviation. For added strength, gloss, and longevity, aircraft paint professionals frequently blend the two compounds.


Epoxy is a polyurethane paint with excellent adhesion to aircraft fuselage and external surfaces. It is a non-hard drying paint that has greater chemical and heat resistance as well as electrical insulation than enamel. Epoxy provides a more flexible finish with improved protection and is less likely to fade, develop cracks or brittleness, break down, or oxidize.


Because of its great durability and chemical resistance, enamel is a low-cost aircraft paint preference. It withstands severe weather and extreme high-altitude conditions remarkably well. It is a fast-drying compound that helps increase painting turnaround time, allowing planes to return to service faster. It fades and oxidizes slowly and includes varnish, which provides an instant and long-lasting sheen. Enamel is less dangerous to work with, and unlike epoxy, it does not generate toxic fumes during application.

There are also additional paint varieties, such as pearlized mica paint, which contains minute aluminium particles and unique colors to produce attractive dazzling effects. These paint types produce advanced special effects for very complicated liveries and graphics. They frequently need specialized training and can be very expensive. Depending on use, aeroplanes might receive a fresh coat of paint every seven to ten years. Commercial aeroplanes that operate continuously require repainting every five to six years to avoid worm corrosion in the space between the paint and the metal.

Gorgeous Aircraft Paint Jobs

Airlines frequently compete by emblazoning their aircraft with the most eye-catching and vibrant paint schemes.

The fuselage of Chinese Southern Airlines' Boeing 787 Dreamliner is adorned with an extensive assortment of blue colors, topped by an exceptional, dazzling red kapok blossom on the tail.

The Malaysian Airlines Airbus A380 blue stripes color scheme is attractive yet subtle.

Why White?

Heat Reflection: White paint reflects sunlight, reducing the amount of heat received by the fuselage of the aeroplane. This contributes to a lower cabin temperature and minimizes the burden on the air conditioning systems. It also helps to prevent excessive heat from expanding the aircraft's structure, which might hinder its performance.

UV Radiation Protection: White paint offers better protection against the sun's damaging ultraviolet (UV) radiation. UV radiation can cause fractures, fading, and other damage to the structural integrity of the aircraft's surfaces. White paint functions as a barrier, reflecting a large percentage of UV light and limiting its impact.

Visibility: White is a very apparent color, especially against the sky. It increases the visibility of the aircraft to other pilots, air traffic controllers, and ground personnel. This visibility is critical for flight safety, especially in low-light settings or when aircraft must be noticed immediately on the ground.

Branding and Identification: Many airlines pick white as the foundation color for their aircraft because it provides a neutral backdrop for branding components such as logos, airline names, and livery designs. White highlights these distinguishing traits and ensures uniform brand representation across the airline's fleet.

Maintenance and Inspection: During routine maintenance checks, white paint makes it easier to notice cracks, corrosion, and other indicators of deterioration. It creates a contrasting background, making it easier for maintenance professionals to notice any faults and take proper action.

While white is the most prevalent color for commercial aeroplanes, there are several outliers. Different colors or liveries are utilized by several airlines and military aircraft to express their branding, national identity, or operational requirements. Nonetheless, the practical advantages of white paint make it a popular choice in the aviation industry.

Opportunities and Difficulties

While the aviation paint industry is thriving, it is not without challenges. The sector is governed by stringent rules on safety, ecological impact, and quality requirements. Adherence to these requirements necessitates ongoing research and development activities. Furthermore, the industry must handle the growing demand for environmentally friendly coatings that lessen the environmental impact of aircraft operations. These difficulties, however, create opportunities for innovation and progress. Companies will be able to get into the rising market of environmentally concerned airlines and passengers if they develop sustainable and eco-friendly paint solutions. Embracing new technology and investing in research and development may help businesses stay competitive and fulfil the industry's changing expectations.


In conclusion, aircraft paint goes beyond its visual appeal and plays a vital role in the operating cost of an aircraft. By choosing the right paint, operators can improve fuel efficiency, reduce maintenance, and repair costs, enhance resale value, and optimize overall performance. The selection process should consider the operating environment, lifespan requirements, color schemes, and budget constraints. A well-informed decision can lead to significant cost savings and increased operational efficiency.
