HiI program my FMC for a flight no prob then takeoff connect the autopilot with VNAV and LANAV engaged, then the plane starts to go into a descent and the throttles retard to IDL.I am using FSINN on Vatsim do the 2 programs conflict?

This sounds like something that happens on sequential flights. If not, I have not read anything here about such a conflict but I'm not a Vatsim user. If it is a sequential flight, my work around to the problem is to ensure the FMC is cleared (all pages) between each segment and I takeoff with manual throttle, engaging A/T with LVL CHG speed control after flap retraction, after which time everything works normal.Forum rules ask that you sign your posts.
