Hi Fly Airline, with principal sustainability partner the Mirpuri Foundation, and The Aircraft Performance Company GmbH push the reduction of greenhouse gas emissions of in-service aircraft forward – by introducing the new multi-fingered Plug&Fly Retrofit Wingtip Solution TRINITAIR.


  • New wingtip TRINITAIR is capable of reducing fuel consumption by up to 2% and on particular applications even more. In aviation for every kg of fuel saved carbon emission is reduced by 3.16 kg.
  • Hi Fly will be the first airline in the world to go on a flight with this new technology, supporting the transformation to a greener environment.
  • The new climate-saving and greenhouse-gas-emission reducing project will have its maiden test-flight on a Hi Fly A330.
  • This pioneering initiative to create sustainable innovation will forever revolutionize the aviation industry.

We are pleased to present the new wingtip TRINITAIR, capable of reducing fuel consumption by up to 2% and on particular applications even more than that. In aviation each kg of fuel saved on a flight reduces CO2 emissions by 3.16 kg. This unprecedented equipment will bring airlines not only financial benefits; they will also enable them to strongly reduce their environmental footprint.

This pioneering initiative to create sustainable innovation, that will forever revolutionize the aviation industry, is now on its final phase. The new climate-saving and greenhouse-gas-emission reducing project will have its maiden test-flight on a Hi Fly A330. Hi Fly will be the first airline in the world to go on a flight with this new technology, supporting the transformation to a greener environment.

“In an industry that is increasingly more concerned with a sustainable planet, and which is looking to have a positive impact with its day to day operations, investing in environmentally friendly technology is the right way to a better world”, says Paulo Mirpuri, President of Hi Fly and the Mirpuri Foundation.

The new wingtip provides an enhanced aerodynamic solution, assisting aircraft manufacturers and airlines to reduce their CO2 emissions. TRINITAIR was designed by The Aircraft Performance Company GmbH (The APC) as a cost-effective retrofit solution for valuable in-service aircraft. Along with a downtime of less than one day for installation, the new hardware brings performance enhancement, lower engine wear, range extension and payload increase as well as a significant reduction of fuel burn that leads to lower emissions of CO2 and NOX.

Harald Zirngibl, Managing Director of The APC, explains that “With its 3-finger wingtip solution, born from a sketch on a napkin, The APC is developing a new technology that enables aircraft to reduce its carbon footprint. The new winglet not only reduces fuel consumption, but also optimizes the overall performance. The engineers at The APC uses well-founded, patented knowledge of flow and structural mechanics to achieve an optimal circulation distribution of the outer wing by locally influencing or expanding the wingtip vortex. A flight from Frankfurt to Hong Kong, for example, would save at least 1.2 tons of fuel. Applied to global air traffic, this means a considerable overall reduction in fuel and thus in CO2 emissions. The handling of available resources, cost effectiveness and pragmatism are also fundamental. Increasing the efficiency of valuable in-service aircraft will immediately benefit our environment. With the “Plug & Fly” concept, the winglets are airworthy within one day. The use of further resources to optimize the fleets is kept as low as possible. It is not the time to wait for the one big solution that can make aviation emission-free in one fell swoop. Effective and implementable transitional steps must be taken quickly on the way there, which drive and support the entire process – that’s our approach at The APC.”


TRINITAIR is a joint project for the environment supported by Hi Fly and its principal sustainability partner, the Mirpuri Foundation. Teaming up for a cleaner sky:

 The Aircraft Performance Company GmbH specializes in improving aircraft performance and new solutions for greener aviation. The company’s focus is set on design and performance improvements resulting in increased fuel efficiencies of legacy and next generation aircraft, offering turnkey programs that emanate from creativity and curiosity and transform hands-on solutions into a tangible reality. The APC’s first product is the retrofit-able multifinger-wingtip TRINITAIR, a technology that provides an enhanced aerodynamic solution supporting aircraft-manufacturers and airlines in their commitment to reduce CO2 emissions.

Innovation and science are a part of the Mirpuri Foundation’s DNA. Consequently, the foundation continually invests in initiatives and technologies capable of making a difference in every area it acts in, and the aviation sector is no exception. In a normal day, close to 100.000 flights take off in different directions around the globe. In an average year, close to four billion passengers travel on commercial aircraft, a number that is estimated to double in the next 20 years. Conscious that this is a polluting industry that is necessary for economic development, the Mirpuri Foundation is committed to minimizing its environmental repercussions.

The Mirpuri Foundation is a non-profit organization based in Portugal, and founded by entrepreneur Paulo Mirpuri with the aim of contributing to a better world for future generations. With its belief that leading by example is the best way to change mindsets, the Mirpuri Foundation fosters cooperation between legislators, corporations, communities and individuals. The Mirpuri Foundation acts in six distinct areas: Marine Conservation, Wildlife Conservation, the Performing Arts, Social Responsibility, Medical Research and Aerospace Research. The foundation’s commitment to sustainability is transversal and is reflected in all its activities. The Mirpuri Foundation is synonymous with technology, research, information and innovation. Allied to these characteristics are the values of integrity, perseverance and altruism in order to better impact the planet. To find out more visit www.mirpurifoundation.org
