Yet another glitch related to Hong Kong International Airport’s new air traffic control system was reported on Sunday.
At about 5pm, a subsystem – the Tower Electronic Flight Strips (TEFS) system – encountered issues “temporarily and intermittently”, the Civil Aviation Department (CAD) said.
A spokesman said in a press release on Sunday night that when the problem arose, the workstations at the tower could not process the flight plan data of some departure flights. Relevant information was then temporarily provided by the tower control centre.

The glitch in the TEFS, which has provided flight plan data for departure and arrival flights to air traffic control officers since 2012, when the old air traffic control system was in use, did not affect the operation of the new air traffic control main system.
It resumed normal operation at 6.18pm after being fixed and rebooted, with the data being verified.
The department said operation of the new air traffic control system and the tower control centre was not affected by the issue.
“Flight movements at the Hong Kong International Airport were generally in normal operation. Aviation safety has not been undermined,” the spokesman said.
Don’t just fix the air-traffic control system, fix the department that runs it
The HK$1.56 billion Auto Trac III system by Raytheon has faced teething problems since it went fully operational on November 14. The department stressed that aviation safety had not been affected despite the issues.
Th CAD said on Sunday that an independent expert panel on the teething issues had had its first meeting on December 16, and the department agreed with the views from National Air Traffic Services, an independent consultant of the Transport and Housing Bureau.
The experts held that given the complexity of the new air traffic control system, even with all reasonable efforts and endeavours, there could still be the possibility of having setbacks during its introduction.
The panel will give advice to the department chief on the new system’s teething issues next year.
