Which immediate consequence results from airflow separation across an aircraft wing?

💡 Explanation

Flow separation prevents the wing from generating lift; this causes a stall because the boundary layer detaches from the wing's surface, dramatically reducing lift and increasing drag; rather than streamlined flight, catastrophic descent ensues.
