Which risk increases when ice accumulates unevenly on an aircraft's turbine fan blades?

💡 Explanation

Uneven ice accumulation raises the risk of engine vibration and imbalance because mass distribution changes during rotation initiate destructive resonances, therefore generating instability rather than consistent compressor behavior, differing from fuel flow or thrust issues.
