Hi, when I open the FMC on my 737, it appears the message 'datalink no comm' on the right corner of POS UNIT. What does that mean?I also noticed that my FMC gives me no ETA as well as fuel to the waypoints. Is this related to this message? Am I doing something wrong while programming my flight? What should I do to fix this?Thanks in advance.Alessandro

Alessandro,The abscence of fuel predictions and ETAs are most likely due to a malprogrammed route. It has nothing to do with the 'DATALINK NO COMM' message.The above message is most likely a static message for the ACARS portion of the CDU. The ACARS functionality is not implemented on the PMDG A/Cs.Hope it helps,

Ok thanks a lot. But do you have an idea what should I do to solve the ETA problem. I input all wpt, spd and altitude restrictions and I thought the FMC could calculate automatically ETA
