Vietnam to use ADS and CPDLC on Some Routes

Vietnam's Thanh Nien Daily is reporting that Vietnam will soon use ADS (automatic dependent surveillance) and CPDLC (controller-pilot datalink communications) to exchange information with certain flights between Ho Chi Minh City and Singapore over the East Sea.

The Vietnamese Civil Aviation Administration announced its intention at a meeting of ICAO's FANS (Future Air Navigation System) Implementation Team this week in Ho Chi Minh City.  The system will be deployed in March, according to Vietnamese officials at the meeting.

ADS automatically downlinks position data from an aircraft without pilot intervention.  CPDLC allows for direct exchange of text-based messages between the controller and pilot instead of traditional voice transmissions.

According to the report, some controllers at the air traffic control center have already been trained to use the systems.  01-20-2007.
