Which circumstance will cause aircraft stall during flight?

💡 Explanation

Aircraft stall happens because exceeding the critical angle of attack causes airflow separation. It's called stall *angle exceeding* rather than turbulent conditions, because stall occurs predictably at a specific angle regardless of airspeed within normal operational ranges, therefore resulting in loss of lift.
