Today I was doing some circuits in the 737-700; programming approaches, etc -- basically, I land, roll out, flaps up, taxi to the opposite runway, stop short, program the FMC for the next leg.The problem is that the FMC doesn't seem to adjust its settings for another flight; when I land at any airport and program the next leg, the REF page does not reset itself? I mean -- calculating the new fuel load and flight levels -- because on the next outbound leg, vnav doesn't work unless I manually set the altitudes in the legs page ... I'm not sure if I'm explaining it correctly :S

I found that if I delete the fuel and weights the FMC will recalculate when clicking the associated select keys....not sure if that's the right way or not.

Maybe deleting the RTE would do, but it wouldn't be the best solution if you're doing multiple legs.If everything works fine the way you do it... then stick with it.

Burhan,I know some users have reported problems with multiple legs. To reset the route in the FMC you need to delete the ORIGIN airport on the 1st RTE page (as in the real aircraft). This 'should' reset the FMC. You might need to manually delete some entries. Hope it helps,
