Hi Everyone,I am wondering if someone can help me. If I select a dp SID and it has an altitude restriction, the FMC generates the flight plan with the crossing altitude of that certain waypoint. But after that, all other waypoints do not have altitudes unless I enter something in.Could you please advise on this procedure? Let's say the SID restriction is to cross ABC at 15,000ft. The next waypoint, XYZ is listed but doesn't calculate the next waypoint altitude unless you do something. If my final altitude is FL350, what do I enter in the next waypoint after the crossing restriction??If I enter in 35,000ft, It calculates something like FL430 which isn't even my programmed final altitudeI hope that makes sense.Thanks for the help.BrianKPHX

Makes sense to me. -=D As far as the FMC calculating what altitude you'll be at at such and such a point, it should do that, and be quite accurate depending on a couple of things. Your 3 IRSs MUST be aligned or you will get erroneous data or no data at all. Your route must be activated. Doing a dry run, just for testing purposes in regard to your question, I also found the calculated data wasn't as accurate as it could be until I filled out the necessary PERF INIT information such as ZFW, Cost index, reserves, and whatever else is listed on that page. This is also the page where you can take care of your second problem. On the right of the FMC, at LSK 5R where it says STEP SIZE, enter 0 (zero) in the scratchpad and enter it here. The default should be ICAO meaning the FMC will automatically adjust the legs page to reflect the optimum altitude you'd be passing each waypoint at. You can enter ICAO which will step you up 4000 feet at each step, 2000 which will, of course, step you up 2000 feet, or you can enter 0 which will leave it up to you to decide. Once you enter 0 in this spot, the highest FL your legs page will show is what you'll have listed as the Cruise Alt on the PERF INIT page. You can also access this information by selecting the VNAV button below the scratchpad. Hitting NEXT PAGE button will take you to the CRZ page where you can adjust the step size and the cruise altitude. You can also see what your current, optimum, and maximum flight levels will be for your current gross weight. All of this is explained in the manual quite thoroughly. Perhaps you skipped over it. They really didn't leave out much when they wrote that manual. It's a great source of information.Regards,Dan Zollnerhttp://jdtllc.com/images/RCsupporter.jpg
