Beijing Daxing International Airport completed flight checks when a plane landed safely at the airport at 10:20 a.m. Sunday.
The flight checks lasted 34 days and ended 19 days ahead of schedule.
Seven instrument landing systems and one navigation system, among others, went through thorough checks.
The completion of the tests means the airport is ready for operation, authorities said.
Set to open in late 2019, the new airport sits at the junction of Beijing's southern Daxing District and Langfang, a city in Hebei Province.
The new airport is expected to handle 45 million passengers annually by 2021 and 72 million by 2025.
