Aviation leaders tackled barriers to growth and the impact of geopolitical tensions on the eve of the Singapore Airshow on Monday, while reaffirming pledges to reduce emissions.
Supply chain problems are hurting global airlines and will remain for some time to come, the head of the International Air Transport Association warned industry leaders and regulators.
"This disruption continues to have a major impact," IATA Director General Willie Walsh said at the Changi Aviation Summit, ahead of Asia's largest air show.
Planemakers Airbus and Boeing have faced supply chain problems since the COVID-19 pandemic, while engine makers like GE Aerospace and Pratt & Whitney are having to juggle competing demands from new plane assembly and maintenance.
Aviation is also navigating geopolitical changes including US import tariffs that have upended flows of air freight.
"I think the impact of geopolitical change was much more obvious on the air cargo side of the business than on the passenger side," Walsh said.
Air cargo shipments between Asia and North America slipped 0.8 percent last year in the first such decline for some time, while volumes between Europe and Asia increased by 10.3 percent, he added.
The Asia-Pacific region is the world's fastest-growing region for air travel, propelled by China and India, with passenger traffic growth of 7.3 percent projected for 2026.
Toshiyuki Onuma, newly elected president of the governing council of the International Civil Aviation Organization, the United Nations' aviation body, warned aviation would struggle to keep up with projected growth without coordinated action.
"A system built for 4 billion passengers cannot support three times that number without transformation," he said. "We must also accelerate progress to achieve net-zero carbon emissions by 2050."
SUPPLY CHAIN 'WEAPONISATION'
The gathering of 350 aviation leaders comes as tensions over aircraft certification threaten to disrupt a decades-old system of globally accepted norms and trade in aviation.
Onuma did not make direct reference to the dispute over US President Donald Trump's demands last week for Canada to certify certain US-designed Gulfstream business jets or face tariffs.
But he stressed the importance of global cooperation in securing the industry's safe development.
"Only together can we achieve a sector that is safer, more sustainable and more competitive," Onuma said.
Trump's comments have raised alarm among airlines and certification specialists who questioned whether aircraft certification could be influenced by politics.
"There can be no bargaining over certification," a senior regulatory official told Reuters.
EU Transport Commissioner Apostolos Tzitzikostas became the latest senior figure to warn of the "weaponisation" of supply chains as major powers pursue their geopolitical agendas.
"Today, (there are) real issues in developing the growth of aviation in the years to come...issues of weaponisation of dependencies in supply chains," he told the conference.
His comments echoed a warning last month by France's aerospace industry over the fate of cross-border supply chains fuelled by globalisation policies that are now in widespread retreat.
Aerospace executives say rare earths remain a particular pressure point despite a US-China trade truce.
