Establishing advanced air mobility (AAM) across the world presents a range of complex challenges that span technological, regulatory, infrastructural, and societal domains. These include the development of a robust and harmonized regulatory framework, Infrastructure development, public acceptance and trust in AAM vehicles, particularly in densely populated areas, standardizing certification processes, and coordinating international efforts. To overcome these challenges, governments, industry leaders, and communities must collaborate closely to create scalable, equitable, and sustainable frameworks that support the safe and efficient rollout of AAM on a global scale.
