A poster asked about CPDLC.
Yes SINGAPORE AND HOCHIMINH both have and use CPDLC ADS-C
However on the flight plan MH370 used they would have gone straight from Lumpur Control to Hochiminh and NOT spoken or logged on to WSSS.
They may have logged on to VVTS....? VVTS ATC haven't said.
But yes VVTS CPDLC does work and I use it all the time.
