May 23, 201511 yr I posted this in the wilco support forums but the forum seems to be deserted lol. I was planning a flight when this message popped up on the FMS Check alt constraint. What does that mean and how do I clear it? Inigo Montoya
May 23, 201511 yr It means the CRZ altitude set in the FMC doesn't match the altitude set in the MCP. DJ
May 23, 201511 yr Author You mean that the fmc is mad because the altitude I dialed in, isn't the same as my final Cruise altitude I put into the perf init page? My initial clearance was for 11000 but my final altitude was going to be 35000. So just ignore it then? Inigo Montoya
