FMC init calculations negative values on second leg

After landing and starting second leg with blank init page, the second page values are in negative. Negative takeoff weight and fuel. I cannot set V2 speed on MCP and activate it then set 250kts like normal either. The other parts of flight work OK when flying second leg but INIT B values do not calculate correct.

Heya,

just quickly letting you know that I´ll test this tomorrow as I´m about to go to bed.

I´ll let you know my findings then 🙂

Thank you! The flight went well but the FMC did not like doing a second leg. I checked the init b page after landing the second leg and the calculations were worse.

After that happened last flight on my new flight this evening, I could not activate the V2 speed and then set 250. I push in speed dial and nothing lights up.

Sorry for the long turnaround time for this!

I just completed a flight and set up a new one directly afterwards and I can´t replicate this.

I know this is a hassle, but could you please try with an empty community folder?

My weights were pounds not kgs if that helps. And panel state I loaded the on GPU. I may have time this weekend to try it again with a clean install.

I did it with kg, so maybe there is the issue. I shall try again tomorrow with pounds 🙂

My flights are done in pounds as well so maybe there is a connection there...  And fwiw, after loading into the plane I select "on apu" panel state. Additionally, after landing, I use APU not GPU or external ground power while at the gate setting up next flight.
