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.

Regular turbofans will kill geese at basically the same rate as this and would be just about as dangerous as well. But moving parts outside of shielding will be louder, as more sound energy will make it to the fuselage.
