HiI am a first time user of the 737NG. The porblem i have is that when i put in the origin and destination for my flight, then whne i click the dep/arr button on the fmc i get no runways and no dep. sid/stars. I have the sid/stars file n ave the the latesr AIRAC could any one help please!!!

Hmmm, what directory did you install the AIRAC and SID/STAR to? Which files resides in the (FS)/FMCWP/Navdata-folder?Any error messsages? Can you give us some info of the departure an destination airport?

One other suggestion, take a look at the tutorials here on AVSIM and on the PMDG web site (documentation under downloads section).A little reading will go a long way in helping you get things going. :-)
