JohnSherman 1 #101 December 21, 2011 Quote First there is no FAA approved standard or requirement for field riggers to do this. Second, there is not an approved testing measure in the PTS to assure riggers are competent to do this. Third, the regulations state that the rigger shall have enough knowledge, skills, and equipment to do the work at hand. The pertinent information would be put in the owners manual. As such you would be required to follow it. Quote We are one of the largest rigging lofts out there in the field and we do not do this, nor have the equipment set up for this, nor any training to assure proper test results. You don't have a scale which will go to 100 pounds? How do you measure ripcord pull force? Quote With that said, do you actually think smaller lofts and riggers working out of their car trunks do this? The answer is a big "NO"... I guess they can't afford a fish scale either. Quote Fourth, it is the manufacturer's responsibility to determine what works with what in the aviation world. ANY aircraft part has an application list as to what it will fit, works with and is certified for. The manufacturer would determine the Effective Square Footage of their pilot chute and placard it as such. They would also placard the container as to what the "Effective Square Footage" of the pilot chute to be used must be. The rigger would confirm the compliance of the ESF relationship then they would use a fish scale to measure the extraction to confirm the compliance of the pack job.

riggerrob 558 #102 December 22, 2011 Wouldn't it be simpler to just state "maximum free-bag extraction force of "X" pounds when pulled at such and such an angle?" Trying to refer to "effective pilot-chute area" involves complex technical terms that are way over the head of the average rigger. Fancy aerodynamic terms are best left to diploma'd engineers.
