← TechnologyWhich outcome occurs when a fixed-wing drone stalls?
A)Lift decreases abruptly and drastically✓
B)Thrust increases due to engine surge
C)Drag is minimised for autorotation
D)Angle of attack matches airflow
💡 Explanation
When sufficient angle of attack causes boundary layer separation, the lift degrades rapidly due to *stall*. The lift coefficient plummets because the airfoil is no longer effectively generating lift, therefore lift drops drastically, rather than allowing improved autorotation found in rotary aircraft.
