Hello.PMDG 737 NG is a great product and I'm a real fan. The only thing I think that blemishes its realism is the intermittent movement of throttles in A/T mode, ASI and ND display problems. Airspeed readout is not like the one in a real PFD. Similarly, an ADF RMI and a VOR CDI in the ND doesn't move as it does in a real 737 ND. They all move intermittently, but not continuously (especially while crossing over an NDB). I checked user videos in youtube and figured that it's not my computer or software. I hope the respectable fellows designing the NGX fix these issues and release it with maximum possible realism.Have a nice flight!TKPilot
