FSMetar 1.5.2 A Real Weather utility by Ivan Jose Alverez downloads weather form one of 3 possible sources and updates MSFS via FSUIPC as needed depending on aircraft location. Can be run in both on-line and off line mode and creates weatherscapes that are the best I've seen in MSFS. Works much better then the Jeps service built into MSFS2004. Requires FSUIPC.
FS AutoStart This neat little utility by Ken Slater will allow you to select which programs and services should be shut down before MSFS starts. In addition it gives you the option of restarting specified services at session and end as well as launching specific MSFS support programs and memory defrag. Once it's set up, all of this is done automatically every time you launch MSFS. Works with Windows 2K and XP.

AI View

AI View is a tactical display plug-in from Altingsoftware.com. Displays position and relevant data for all AI aircraft, both on the ground and in the air. You can also click on any aircraft description for a real-time spot view of the aircraft in action. At 26K it's a tiny download and installation couldn't be easier. Just drop the DLL into your MSFS2002 modules folder and the application will be available on the MSFS menu bar. A neat add-on that shows the power and simplicity of the MSFS plug-in system.
