That seems to have solved the problem. I apologize byork for assuming it was FS2CREW.

From what I have read it is when there is a loss of A/C power then the aircraft will set to only one FMC to conserve power. It seems there is a quick loss of power when the FO switches from ground to the APU. I will do mre testing on this. I have never had this problem before.

As soon as the FO sets the APU on the bus I get a FMC SINGLE OPERATION message. This did not happen until the latest update this week.

JimThis was happening for over an hour I tried many diffrent flight plans rebooted several times. Then loaded Fs9 in Seattle opened AS6 rfreshed weather came in like it should but now after doing that weather works fine with saved flight plans. Who knows it may just have been internet problems. I live outside of Boston.Thanks for your effort.Michael Ransom
