International Civil Aviation Day

  The International Civil Aviation Organization ( ICAO ) has been shaping the international civil aviation sector since its establishment in 1944. As we enter a new era marked by unprecedented challenges and opportunities, ICAO has developed a comprehensive Long Term Strategic Plan for 2026-2050 that aims at the orderly growth of international aviation, guiding our efforts in  leading the sector toward a more safe, secure,economically viable, efficient, and environmentally sustainable aviation sector . This Strategic Plan comes at a decisive moment for international civil aviation. Traffic growth has resumed and is forecast to accelerate. This will also increase facilitation challenges to manage this growth. While ICAO continues to support Member States  in their ongoing efforts to comply with current international standards, it is important to anticipate and prepare for the world that lies ahead. New types of highly automated aircraft are approaching entry into servi...

  Innovation — recognizing the real and potentialbenefits and challenges that innovation can bringto the air transport sector and providing Member States with the tools, knowledge and mindsets to realize these benefits in a manner that leaves no country behind . Innovation actively promotes ideas on new ways of doing things that support the Organization’s Strategic Goals and increase the efficiency and effectiveness of ICAO . The aim is to encourage innovation to be embedded throughout ICAO ’s work. Innovation in air transport brings huge benefits like faster, connected travel, economic growth, and better passenger experiences (AI, UAM), but faces major challenges: achieving sustainability (emissions), high costs, complex supply chain disruptions (Boeing/Airbus), cybersecurity, and workforce shortages, all while integrating new tech like electric planes and Installing AI into a heavily regulated system.

  The International Coordinating Council of Aerospace Industries Associations (ICCAIA) and the International Business Aviation Council (IBAC) members are committed to advancements in all fields including aerodynamics , propulsion, aircraft systems and Structures technologies , Aircraft manufacturing technologies and all types of potential energies (sustainable aviation fuels, electricity and hydrogen). Aircraft technologies are focused on increased efficiency and carbon emissions reductions as a way to reduce aviation’s climate impact over the long term . In the short term, Sustainable Aviation Fuels (SAF) have a greater role in decarbonisation than other mitigation measures as these “drop in” fuels will reduce carbon emissions from thousands of aircraft already flying. In 2021, the Air Transport Action Group (ATAG) released the second edition of its Waypoint 2050 report . This report highlighted the commitment of its members to net zero carbon emissions operations by 2050. Bus...

  The “traditional” (pre-2010 generation) and “advanced” (current generation) tube and wing aircraft will begin to be superseded in the 2035 to 2050 timeframe by “advanced concept” aircraft. These concepts will produce a step change reduction in fuel burn, based on the vehicle aerodynamic configuration, improvements from advanced flight controls using stability augmentation to reduce drag, achieve structural optimisation, and enhance propulsion system integration. Various new aircraft types and configurations from Urban Air Mobility  to light jets and turboprops to large civil single aisle and twin aisle aircraft are expected to make wide and varied use of a range of more specific technologies, explored below. Figure 2 shows an example of an advanced configuration business aircraft. Important guidance for this effort is provided in the latest revision of SAE document ARP 475 ( Guidelines for Development of Civil Aircraft and Systems ) and ARP 476124 ( Guidelines and Methods f...

  In addition to full vehicle configuration reshaping , there are many local (i.e. wing, fuselage, stabiliser) geometryimprovements expected in the next 15 years. These include improved wingtip devices, laminar flow control, morphing wing shapes and skin surface riblets. (See Figure 3). Aerodynamics . Important guidance for this effort is provided in the latest revision of SAE document  ARP 475  ( Guidelines for Development of Civil Aircraft and Systems ) and  ARP 476124  ( Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment) . 

  Airframes of advanced concept aircraft are benefiting from optimal structural topologies. The efficiency of structures capable of withstanding extreme loads is ever increasing, reducing the overall weight and influence of the airframe on aircraft emissions . Newer and better load alleviation technologies are emerging, and so are beneficial weight reductions inherent in Improved manufacturing processes . The enhanced ability to apply these technologies and improved production processes across a wider range of aircraft sizes also broadens their benefit to the overall fleet. Important guidance for this effort is provided in the latest revision of SAE document  ARP 475  ( Guidelines for Development of Civil Aircraft and Systems ) and  ARP 476124  ( Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment) . 

  Lightweight materials and alloys have continuously improved in the ratio of weight to load carrying capacity over past generations of aircraft, and this trend is expected to continue and diversify for development of future. The use of new alloys requires processes that are closely linked to the load alleviation technology mentioned above. Structures addressing the types of loads and necessary characteristics of materials will be Produced as “designed composite materials” in place of past reliance on available“raw” materials. Important guidance for this effort is provided in the latest revision of SAE document  ARP 475  ( Guidelines for Development of Civil Aircraft and Systems ) and  ARP 476124  ( Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment) . 

Important guidance is provided in the latest revision document  ARP 475  ( Guidelines for Development of Civil Aircraft and Systems ) and  ARP 476124  ( Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment) .  The recently launched CLEEN Phase-III focus areas include fuel burn reduction via fan module technology, combustor and HPT technology, open fan technology, and highly integrated hybrid-electric systems (see Figure 5). Another focus area is SAF development – both qualification/ASTM standards maturation and increasing blend ratios to up to 100%. Europe’s Clean Sky 2 joint technology initiative aims to develop and demonstrate breakthrough technologies for civil aircraft that could reduce C02 emissions by 20%   (2025) to 30% (2035). Focus areas have included contra rotative open rotor (CROR) demonstration, design/test of a turbofan LP spool and nacelle technologies demonstrator, and testing of v...

 The airspace users grow in numbers and evolve   The airspace will host new types of aircraft , such as drones and VTOLs / eVTOLs    There’s a closing prospect of a need to manage both conventional and new types of aircraft sharing the same airspace – establishing regulations , infrastructure, training for professionals etc. Discover the  Unmanned Aviation and Advanced Air Mobility .

Aside from glass cockpits and digital fly-by-wire, basic commercial aircraft technology has changed little in the past three or four decades. But the next 5-10 years could see a revolution of sorts. Researchers are racing to design, develop and commercialize passenger aircraft that reduce emissions and noise pollution with Tesla-type battery power or cruise above the congested ground traffic of megacities. What’s the status of electric aircraft dreams? Where might they fit into the future commercial aviation scheme? AB INITIO TRAINERS?  Despite the hype of recent announcements about regional airline-size aircraft, the initial application of electric propulsion is more likely ab initio flight training. “The transition from training on an electric airplane is ideally aligned with a turbine aircraft like an airliner,” said George Bye, founder of Bye Aerospace in Englewood, Colorado, US, and designer of the transonic Javelin advanced jet. He was also FlightSafety International’s projec...
