Question

One purpose of the four line jettison system on the automatic back parachute is to ________.

1) increase stability during descent
2) reduce the risk of entanglement
3) decrease the rate of descent
4) improve the opening sequence

Answer 1

2) reduce the risk of entanglement. The purpose of the four line jettison system on the automatic back parachute is to reduce the risk of entanglement.

Step-by-step explanation:

The purpose of the four line jettison system on the automatic back parachute is to reduce the risk of entanglement. When a parachute is deployed, the lines can become tangled, which can lead to instability or failure. By jettisoning, or releasing, the four lines, the risk of entanglement is significantly decreased.

This system does not affect stability, descent rate, or the opening sequence of the parachute. Instead, it is specifically designed to address the issue of entanglement.
