Which mechanism drastically increases drag when airflow separates around an aircraft wing?

💡 Explanation

An adverse pressure gradient induces turbulent separation, which then drastically increases form drag. This occurs because flow reversal prevents pressure recovery, therefore raising drag rather than other effects associated solely with skin friction.
