In simplest terms, there are two forces involved. The drag force capability of the pilot chute and the force required to extract the bag. Certainly, the ability of the pilot chute must be greater than the retention of the container. This demands that we know the capability of the pilot chute. To know this requires testing with instrumentation. However, we can calculate the size requirement of the pilot chute and measure the bag extraction force without doing sophisticated tes

The purpose of this article is to illuminate on the facts necessary for jumpers to make an informed decision
