How are the two batteries ventilated during ground operations?

The correct response highlights that during ground operations, the two batteries in the Dassault Falcon 2000LXS are ventilated by a battery-powered blower when the BAT 1 switch is activated. This method ensures efficient airflow and temperature management around the batteries, which is crucial for their performance and longevity.

When the battery-powered blower is engaged, it actively moves air around the batteries, aiding in the dissipation of heat generated during their operation. This active ventilation system is particularly important in ground operations where natural airflow might be limited.

In contrast, while aerodynamic airflow and natural convection can contribute to ventilation in various situations, they do not provide the focused and efficient cooling that the blower system does. An active cooling system, as mentioned in one of the alternatives, suggests a more complex setup that involves additional components designed to cool systems actively, which is not the case for battery ventilation in this context. Thus, the use of a battery-powered blower effectively addresses the need for controlled ventilation during ground operations.
