August 13, 201411 yr I planned a flight at 34000. Upon checking the legs page before TO I found that page 2-3 the FL had gone up to 38000(why?) But , as planned I set the MCP to 34000. After some cruising at 34000 the TD appeared on the nav. display. I reduced the MCP to 3000. However, when passing the TD it did not start to descend , even though the path deviation indicator came up showing no deviation. After quite a few miles it did start to descend and all went well.It seemed as if the TD started as if I had chosen 38000! I decided to repeat the flight putting in 34000 again but as it came up with 38000 in the legs again, I set the MCP to 38000. I got into cruise at 38000 but I had to stop to go out- so I saved it in cruise. Later I returned to it loaded but as often happens the panel was all wrong but I loaded the panel state from the saved state in the FMC. By the time this happened it had lost a lot of height so it started to climb back up. BUT- the legs p age now showed 34000!.So I set the MCP to 34000 and all went well at the TD. Has anyone any ideas what went wrong? David David Pedder
