Under the initiative, either Singapore Changi Airport (SIN) or Seletar Airport (XSP) will be used as a testbed to co-develop what CAAS describes as a “comprehensive readiness framework” for integrating open-fan engines and next-generation aircraft into existing airport operations. The work will cover aircraft and engine design considerations, airport infrastructure modifications, changes to operational procedures, safety standards and regulatory processes.
