Which malfunction is prompted when aircraft landing gear doors fail?

💡 Explanation

Failure of landing gear doors causes increased drag at altitude because turbulent airflow from the open bay creates parasitic drag. This is due to increased form drag on the bay, rather than premature thrust reverser engagement since their activation is unrelated.
