Hello,
I don't clearly understand the difference between datalink clerance (DATALINK in the FMS menu) and CPDLC (FANS). I tried to use this functionnality on IVAO at LFPO. Using FANS, I got a clearance, but I did not find the way to display the ATC full message and to send my answer. Should I send my request by Datalink instead (at least on IVAO) ? I read somewhere that Datalink is only used for communications between pilots and technical services. With ATC, the procedure is to use CPDLC. But probably, I'm wrong because the clearance may be requested by Datalink (according to Toto's last video).
Thanks by advance for those who could enlighten me.
Daniel.
