Which outcome occurs when increased air density affects helicopter rotor blades?

💡 Explanation

Increased air density results in increased aerodynamic lift because the rotor blades encounter more air molecules per rotation; therefore lift improves, rather than decreasing rotor speed or causing engine problems, which occur under different performance constraints.
