I have the 737NG 600/700. Other than adding two additional models,with longer range and more realistic FMC, what is the benefit to my 600/700 aircrafts, if I were to add the 700/800 aircrafts? Does the 800/900 add on do anything to the 600/700 aircrafts?I know that the FMC on the 800/900 is more realistic, but are any changes made to the 600/700 with the 800/900 add on?Thank you.Stanner

Every change on the -800/900 is reflected on the -600/700 as well...

It is worth it!Bretthttp://www.precisionmanuals.com/images/forum/800driver.jpg

More than ever. You get the TCAS II logic that works so well in all models, as well as an updated panel(s). Plus, the extra FMC features! It's great.

It is definitely worth it. Of course, right now you might be better off saving your money for the Queen.Andrew

Thanks. I will consider buying it.I have the CD version of the 600/700. If I purchased the 800/900 I would also buy the CD version. I checked in PC Aviator store and there is no mention:1. that the 600/700 must be installed before installing the 800/9002. that the 800/900 updates the 600/700.In PC Aviator store I checked all the changes in the 800/900,are these changes ALL RELFECTED in the 600/700? I suspect that only some of these changes are made to the 600/700. Is this correct?I would not want to buy the update if the majority of the changes in FMC, cockpit, textures etc., are not also made to the 600/700.I love the 600/700, it is my favorite sim.Would appreciate your comments to my questions.

Not sure why, but you should have the 600/700 installed and all the updates the 800/900 come with apply to the 600/700 where applicable. By that I mean, the overhead has some differences in the 800/900 just as in the real world.I'm not aware of any stand-alone 800/900 pack. The FMC improvements, panel upgrades and everything else applies to all models.
