A minimum altitude limit of 304 metres, or 1,000 feet, has been imposed on a flight across Victoria Harbour by the world's biggest passenger plane on Monday.
The limit, imposed on the Airbus A380 for safety reasons, and equivalent to about the 68th storey of the city's tallest building, Two IFC in Central, was announced by the director-general of civil aviation, Norman Lo Sung-man.
The plane, which will fly across the harbour between 8am and 8.30am, would also keep a distance of more than 548 metres from the 88-storey building, Mr Lo said.
The flight will help launch the four-day Asian Aerospace International Expo and Congress at AsiaWorld-Expo near the airport, where the plane will be one of about 10 aircraft on display.
'When we design the flight path and flight profile, we are in constant and regular discussions with the Airbus flight test pilots and simulation team,' Mr Lo said.
All the points for the flight path had been tested at the Airbus simulation facilities in Toulouse, France, and it was considered a safe flight path over the harbour, he added.
