The jet warp issue or warp bug, as it is better known, refers to arriving at the next waypoint in your jet aircraft after a WARP with your engine sputtering and out of fuel.  If you are flying with Unlimited Fuel selected, you will not experience this problem.   

Now this can happen for one of two reasons:

- You WARPED with your throttle wide open over a distance so far that you actually ran out of fuel. 

OR

- You are a true victim of the Warp Bug. 

This bug only occurs in jets using the FS2000 engine, or the FS98 engine with a lot of FS2000 entries remaining in the AIR file.

The Solution is fairly simple.   Replace the FS2000 engine in the AIR file with the FS98 engine, and remove all FS2000 entries from that file EXCEPT the CFS/FS2000 fuel tanks and the FS2000 Vacuum System.  If the plane already has the FS98 engine, then remove the FS2000 entries as above. 

If you need more information, or want help with a specific aircraft, let me know.

The AIR files of the jets in the Fox Four Korean campaigns are good examples of those that are Warp Bug Free.....the player aircraft, not the AIs.
