I have three questions:1)I have looked through the forums and did not find the solution to my problem. Tried ALT INTV but did not work. I am flying at FL320 and had VNAV disengaged (at one point during the climb it was engaged up until ATC's first altitude restriction). Then used FLCH and leveled of at FL320 and asked ATC for FL change to FL340. I have changed the FL in FMC and in ACT RTE LEGS at the next waypoint but when I click on VNAV it gives me 'CHECK MCP ALT" and MCP ALT says FL320.2) How do you set the mach speed in the FMC? Now it just says ------/FL320.3) All of my waypoints (after pressing DATA button display the following info:Waypoint nameALT Restriction-------ZAny reason why the ZULU time is not displayed there?Thanks much for any suggestions you guys may have!Marek

1. The FMC is telling you that you need to change the ALT window .... in your case from 320 to 3402. If you have a cruise mach speed set up in the initialisation it should automatically show in the legs page as 0.78/320 I think you can just type it in alsoPeter

You can also enter the cruise speed on the cruise page.

>You can also enter the cruise speed on the cruise page.Did that as well and no joy...
