Static line parachute automatic activation device

An apparatus for automatically deploying a reserve parachute, comprising:

• a first circuit to generate a first parameter indicative of a distance between a jumper and a jumping platform;
• a second circuit to generate a second parameter indicative of a rate-of-descent of said jumper;
• a third circuit to deploy said reserve parachute if said second parameter indicates that said rate-of-descent of said jumper is at or greater than a predetermined rate-of-descent threshold;
• and
• a fourth circuit to enable said third circuit if said first parameter indicates that the distance between the jumper and the jumping platform is at or greater than a predetermined distance threshold.

A parachute equipment comprising:

• a primary parachute;
• a reserve parachute;
• and
• an apparatus for automatically deploying a reserve parachute, comprising:
• a first circuit to generate a first parameter indicative of a distance between a jumper and a jumping platform;
• a second circuit to generate a second parameter indicative of a rate-of-descent of said jumper;
• a third circuit to deploy said reserve parachute if said second parameter indicates that said rate-of-descent of said jumper is at or greater than a predetermined rate-of-descent threshold;
• and
• a fourth circuit to enable said third circuit if said first parameter indicates that the distance between the jumper and the jumping platform is at or greater than a predetermined distance threshold.
