Which risk increases as jet fuel viscosity decreases?

💡 Explanation

Lower jet fuel viscosity yields less lubrication protecting moving parts, because increased pressure results in easier formation of vapor bubbles. Therefore, the injector pump is more prone to cavitation, rather than effects involving combustion thermodynamics.
