China has invested heavily in the homegrown jetliner as it seeks to become self-sufficient in key technologies, but many of the C919’s parts are sourced from overseas.
The jet received official certification to fly last year after more than a decade in development but has yet to secure any international buyers.
Reporters and guests were invited to tour the plane on Wednesday, with the following two days reserved for visits from local community representatives.
The C919, which landed in the city on Tuesday, will fly around Hong Kong Island twice on Saturday morning if weather permits, the government added.
