Hi Matthias,
Answers to your questions:
1. If iStation is running on the FSX computer, there is no need for it to connect to WideFS, it connects directly to FSUIPC. Connection to WideFS is only required when running iStation on a remote computer.
2. To enable the real time viewing of ACFT in Google Earth, follow these steps (see image below):
1) Start the data logger (PERFORMANCE tab)
2) Click on the "G.Earth Real-Time" check box.
3) Push the "Google Earth" button.
3. You can disable the Instructor Station logo in Google Earth by unclicking the "Absolute positioning: Top Left" checkbox (as indicated in the image below). If you want to add your own logo, you have 2 options: either superimpose an image in Google Earth, locating it on the desired position, with each data set, or we can customize the logo on your iStation copy for a fee.
Hope this answers your questions!
Best regards,
Luis Gordo
