Re: [TransientCW] LOWEST FF WITH A 42
Also depends on canopy size.
When I was active, I used a 42 quite often in the 220 range with canopies in the c.260 range, after some experimentation I found 42 gave more consistent initial inflation. I experienced a PC hessi once from a delay off 220, with a 46 (never a 42), that made my head pump, properly thought I was going in.
There was also a PC drag table knocking around during that time (I may still have it), that gave some data to this question.
Rule of thumb though was generally 250 upward with a troll 265 I used a 42, without issue.
Some see 42s <300 as "skull collecting", but myself and a couple of others played with this quite a bit and just found our comfort here, YMMV.
Was it sensible, probably not looking back, just made sense to us at the time.
@Pendragon - I always used 120 for SD calcs, seemed to test quite well.
