Stab Trim Indications are Different Between 2D and Virtual Cocpit

[kmanning]

Hi all,I don't know if any of you have noticed but the stab trim indications are a little different between the 2D cockpit and the virtual cockpit. I've tried to search for this but I did not find any information. For example, I go to the virtual cockpit and set my trim to exactly 6.0. But when I go to the 2D cockpit, the indications are 5.6 or 5.7. In case you're wondering how do I know what the indications are from this 2D cockpit view when the indications are too small to read, if you put your mouse curser over the trim window indicator, a small window will pop up and tell you what the indication is. But it may not be correct since it's different from the PMDG virtual cockpit. So why is there a discrepency? It's 5.6 or 5.7 in the 2D cockpit view and 6.0 in the virtual cockpit mode. The only things I can think of is that it's a limitation of FS9 or I need to re-install the simulator. Would someone try this and let me know if you're getting a discrepency like I've memtioned above? If any of you are not getting a discrepency and you get the exact same indication in the 2D and the virtual cockpit, I probably need to re-install my simulator. But if any of you are getting a discrepency, then I'll just assume it's the limitaion in FS9 and I don't need to re-install. I just want to know why I'm getting a discrepency here. So, the next question is which one is actually correct? I assumed that the PMDG virtual cockpit view would be the correct one to use, right?Another small discepency, which is probably not much to worry about, but when I press the B Key on the keyboard to set the correct altimeter in FS, the amber indicator is just slightly below the line, a little bit off. There's about a 1 or 2 inch difference between using the B Key in flight simulator and using the amber indicator on the PFD. So is the actuall correct setting obtained by using the indicator on the PFD? I know the difference is small but the point is, it's slightly different. I assume these discrepencies are just the limitaions in flight simulator. Ken.

"For example, I go to the virtual cockpit and set my trim to exactly 6.0.

Isn't that thousands of feet??? :-)In the real world, I wouldn't be worrying about a hundredth of an inch or two. I've been told that the altimeter is not a precision instrument, in the sense that it shouldn't be used as a reference for landing. If you're relying on baro altitude, to say, flare the aircraft the size of a 747 at a fogbound airport... you could end up with some seriously bent landing gear.The Touchdown Zone (TDZ) comes from the FMC airport database. I believe, depending on how much information you've fed into the FMC, the TDZ will either indicate average airport elevation (real world airports are not always flat)... or threshold elevation for the chosen runway (but don't quote me on that). In MSFS, however, the airports appear to be pretty flat. The RW baro setting most likely comes from a mini weather station at the airport... at a specific hight above the ground. The Air Data Computers on a 747 are probably about 15' above the ground, so there are bound to be some minor pressure variations between the two.All in all... I wouldn't worry about it too much.Cheers.Q>
