Possible Fix: Flight Path Not Displaying on MFD (787)

Hey everyone,

If you’re flying the 787 on PC and your flight path isn’t showing up on the MFD, there’s a quick fix that’s been working for a lot of people — clearing your ROLLINGCACHE.CCC file.

---

What’s happening?

A corrupted or bloated rolling cache can cause the MFD to fail to render your flight path correctly. Clearing it forces the sim to rebuild it fresh, which resolves the issue in most cases.

---

How to fix it

1. Close the sim completely before making any changes.
2. Navigate to your rolling cache location. By default, it’s usually found at:
   C:\Users[YourUsername]\AppData\Roaming\Microsoft Flight Simulator\ (or wherever you set your cache directory in the sim’s Data settings).
3. Locate the file named ROLLINGCACHE.CCC.
4. Delete it (don’t worry — the sim will automatically regenerate it on next launch).
5. Restart the sim and load your flight.

Notes

• This won’t affect your scenery add-ons, aircraft, or any other settings.
• If you’ve set a custom cache location, check the path you defined in Options > General Options > Data.
• If the issue persists after clearing the cache, try disabling the rolling cache entirely as a test to rule it out as the cause.
