OK, after doing everything on the pre-flight FMC, when I press the appropriate RSKs, it won't enter the V-Speeds. I have everything entered and the FMC even says PRE-FLIGHT COMPLETE, but it just won't enter the V-Speeds. Any help?

As I near arrival, I'm now also getting VREF speeds of 220-260KIAS and I only weigh 133,000 pounds. What is going on?

Ron,It seems you have some mismatch between kilograms and pounds. Check your settings in both the FS menu and PMDG Options. ANd be sure they correlate withthe figures you intend to use.Hope it helps,

Thanks, that fixed those 2 problems.One more problem though:During take-off, I arm the A/T, the engine instruments say it is in TO power mode, but when I press the N1 button or CTRL-SHIFT-G for TOGA, the throttles do not automatically advance. What is the problem here?

Don't press the N1 button Press a little screw on the mcp next to the flight directer and autothrottle switch for TOGA roll,pitch, and thrust modes...

Thanks, that worked. :D
