Which risk increases when a jet engine exceeds design RPM?

💡 Explanation

Exceeding design RPM increases flutter because a blade's resonance frequency is approached; this aeroelastic instability leads to catastrophic failure. This is more likely than opaque plume, which signals incomplete combustion, rather than overspeed, and stall is a different instability.
