Hello guys, SATCOM message on the EICAS. Checked QRH, no resolution found, only information that the SATCOM failed. No resolution found in the FCOM either. Returned to stand, company SOP says no departure until solved. I also had a SPLIT IRS message on the FMC so I guess I (again) temporarily lost power when turning off the APUs. Can someone help me out how can I sort out the SATCOM issue? Cheers!
