Good evening,

Some of the Canadian airports I've been flying into lately, the runway heading illustrated on the EHSI is off by 20 degrees or more. This is also corroborated by the FRONT CRS heading displayed in the FMC when shooting an ILS approach. Where is the CS 767 II pulling this information from so I can attempt to fix this? It's pretty bad for situational awareness when flying on VATSIM.

Using the example in the attached image, the arrival airport is CYYR. The runway is 08. According to the charts, the runway heading is 76 degrees. But as you can see from the screenshot, the CS 767 II thinks the runway heading is 98 degrees. It shows 98 degrees in the FMC. It also draws the runway on the EHSI as 98/278 degrees.

Thank you in advance,
Jason Boche

After much troubleshooting and testing, I found the problem. It's a bad AIRAC cycle 2312 from Navigraph FMS Data Manager specifically for the Captain Sim 767 II aircraft. I restored to AIRAC 2311 and all is well again. The bad data is in the file Runways.db.

I've created a forum post at the Navigraph support site:
