The issue with getting EFB to display VATSIM traffic consistently while flying the PMDG 737 NGX has bothered me and my fellow pilots at our VA CANADIAN EXPRESS.
PMDG are about to deliver another Hot Fix for the PMDG 737NGX, we are not sure if the new fix will solve this issue.
We believe we found a work around and those of us who tried it report success.We all run EFB in a networked environment with the Data provider on the FSX PC and the Display Client on a second PC. Any other configuration may not work, your welcome to try and please report back.
Here is our work around.
Start FSX first, Load NGX 737 and start at an airport of your choice. A busy one if you like, EGLL is quite busy all the time
Load Squawk Box and log on to Vatsim. Start the EFB Data Provider on the FSX PC, wait for it to load and confirm it is running, Start EFB Display Unit on the second PC.
Set Up a Flight Plan in EFB. For the test we used EGLL to LSZH - DVR UL9 KONAN UL607 KOK UM150 DIK UN852 GTQ UT3 BLM. Select the altitude, activate the VATSIM sync with EFB and activate the flight.
Make sure FSX is the active window and that TRFC buttons are activated on each screen for EFB. Use VATSPY, SERVEINFO or a similar program to check the VATSIM traffic. If you see the same or similar traffic in EFB then congrats the solution worked for you as well.
Let me know if you get the same results, that is VATSIM Traffic on the ground departure and enroute screens in EFB
Good Luck
