Fuel and FMC - PMDG 737

Recommended Posts

Guest Totti10

I have one question about FMC in PMDG737 (with both -600/-700 and -800/-900 addons). Before takeoff my FMC shows fuel at destination for example about 3.5 (which in the end is the right number). At the top of climb FMC still shows the right number, but always after about 5 minutes of cruise flight FMC shows fuel at destination 0.0 and this number shows me nearly whole flight. About 30 minutes before the top of descent FMC shows again the right number (those 3.5). Is it normal? - where is the problem? Avarage route winds number in the FMC is exactly the same what calculates me ActiveSky 2004, cost index 40. thank you for your helpMartin Olsovsky
