Narrative:

On a student x-country training flight returning to grr, engine began running rough, and requested priority landing from grr tower, on non-active runway. Possible causes of rough engine: carburetor ice, contaminated fuel, low fuel in one tank, possible fuel leak. Actual cause of problem not determinable at this time. However, fuel management on x-country flying should emphasize continuous in-flight monitoring of fuel supply.
