Landing Reference Speech?

Recommended Posts

Hi,the picture shows the PFD during a landing with flaps 25. The FMC-APPROACH page instructs me to take 160 knots as the reference speech, but the PFD shows a REF between flaps 20 and 25. What's the reason. Anybody knows?


Kind regards

Hi Jon,I don't think so. The ZFW was updated just before Takeoff. But there may be a context with the "DISAGREE FUEL" bug. That always shows a smaller value of "CALCULATED" fuel (3-10 tons) after landing. I'll report it in that thread. May be it's interesting...


Kind regards
