What is the function of the drogue chute?

The function of the drogue chute is to help stabilize and decelerate the ejection seat during an emergency ejection. When an ejection occurs, the drogue chute deploys first, creating drag that slows the seat's descent and stabilizes it, preventing tumbling or spinning. This stabilization is crucial for ensuring that the ejected pilot has a controlled descent and can effectively manage the deployment of the main parachute at a lower altitude.

The other options do not accurately represent the primary role of the drogue chute. For example, the drogue chute is not meant to guide the plane, as it is specifically designed for ejection scenarios. It does not serve to increase the seat's altitude; rather, it assists in a controlled descent. Additionally, while the drogue chute is associated with the deployment of the main parachute, its primary function is not to deploy the main chute itself but to ensure that the ejection seat reduces speed and stabilizes the pilot for safe parachute deployment afterward.
