Which mechanism primarily limits maximum achievable rotor lift in helicopter hot-and-high operations?

💡 Explanation

Decreased air density at high altitudes and temperatures reduces the rotor's ability to generate lift because the profile power increases via higher blade angles of attack, therefore lift is reduced rather than engine power loss being the primary limitation.
