Which outcome occurs when a commercial airliner mechanically locks landing gear during extension?

💡 Explanation

Locked landing gear creates local form drag that can disrupt streamline flow and generate turbulent airflow because the mechanism of boundary layer separation increases. Therefore buffeting occurs, rather than asymmetric roll from the gear, or changes to primary flight characteristics.
