AFF vs S/L?

Recommended Posts

Why? With airplanes going routinely to 15k, do we have to burn up every bit? Those still on a decision height of 2500 (As) shouldn't be opening at 3. Bill Dause, btw, uses 4k after 10s of thousands of jumps.
People shouldn't view the min deploy heights like speed limits - as a starting point to be pushed.



I don't want to push this forum off on a tangent, so will be brief. The reason people need to be comfy with 3 grand is because you will inevitably find yourself on bigger loads with more people where you will simply have to track longer - and lower. You may also find yourself at a really busy boogie with multiple airplanes on parallel jump runs disgorging loads all over the place and management may tell you not to open above 3 grand. If people want to pull at 3500 or 4 grand on routine small loads at the home DZ, that's fine & God bless. But safe separation is just as important, and the more people on a load, the harder you have to work at it. Maybe comfy's not the right word, maybe I should've said confident. You don't have to like it, but you should be confident of your ability to take it down lower when conditions warrant.

Bill uses 4k as a BREAK OFF, or deployment? Most organizers use 4k as a break off. That means you have to turn and track, so you deploy around 3k.

he deploys.

I think WFFC's requirement not to be in the saddle above 3 is fine - a throw out at 3.5 meets that, still gives time to deal with issues.

I know a lot of people pressure others in a nice lemming fashion to separate at 4 and deploy at 3, but doesn't mean people have to follow. The second day I had my dytter the third alarm went off (set to 2k) when we were a bit late on our 4.5 breakoff. Seems that others just didn't track much. I was in the saddle right at 2, which is unneccesary risk for anyone (imo, of course)

Encouraging low alts because 'no one will jump with you otherwise' is as nice a practice as encouraging people to downsize.

Not trying to get off track....And I agree that jumpers should ALWAYS stay inside their comfort zone.

But it is true that some people will not jump with you if you want to break really high. YOU have the right to say no and jump on another load. Even if its wrong to pressure people....You can not ignore that it does happen.

So I am dangerous if I am in the saddle at 2 grand? I disagree.

i went through aff , sl isnt even offered where i learned. but i think the benifit to aff is you learn to fly your body better and faster than on static line. i was doing back flips and tracking on my 5 jump, can you do that on s/l and as far as the h&p fear goes yeah it was a little scary jumping out low but you have to realize aff students have to deploy from boc if i was s/l on the jump it wouldnt have scared me as much. after i got my a i had to do one in a real emergency when plane lost a engine haveing the confidence to be able to deploy at a low alttitude when emotions are already high is a great benifit, as for cost aff cost me 1600(10 jumps) and the coaching after cost 1600(15 jumps)

If you believe in an 1800' decision ceiling, planning to be in the saddle at 2 is unwise. A 1s delay in the throw or a snively or spinup on the opening and you have essentially no time to do the canopy check.

It's obviously unwise for my mal free history, but I don't see the wisdom in planning little margin for anyone else either. It's another one of those pick your risk questions - I'm content with just 11-12000 ft of freefall.

Just like you don't think that a 4,000 break off is safe, does not mean that it is UNSAFE given more information.

2,000 feet is fine as a deployment altitude for me and a bunch of other people. It might not be good for you, thats is your call. But a 4,000 foot break off is yours and MY call as well. 4,000 feet can be a safe break off altitude, or dangerous depending on WHO is in the dive.

This right here is an example of the difference between AFF and Static line. AFF grads seem to really hate being low. Years ago when I was at a SL DZ if there were clouds at 2 grand we still jumped. Today of there are clouds at 5 grand the plane sits on the ground.

Ron, you didn't really address my first line referencing the decision altitude. I'm interested in your thoughts there. To me, that height drives the rest of the decisions on deploy and b/o points.

I don't think it has much to do with sl versus aff, not when/if SL jumps are done as high as 3500.

I agree that the hadr deck should drive all other choices....100%

But I don't agree that 2 grand is automaticly dangerous.

SL folks do not seem to be as afraid of low altitudes as AFF folks. You are saying you like 4 grand as a deployment....Well SL folks take a delay from 4 grand.

I grew up at cessna DZs and launching 4 ways from 4 grand is pretty common. (Lots of cloudy days in the NW)

Nowadays you see AFF grads riding the plane down if they only get 4 grand....

Personally I think riding the plane down is more dangerous;)

My s/l progression was this:

Jumps 1-2: Static Line
Jumps 3-5: Static Line w/PRCP
Jumps 6-7: 5 second delays
Jumps 8-9: 10 second delays
Jump 10: 20 second delay
Jump 11-25: All from 10,000'. Two were 3 ways, three were 4 ways (one which got 8 points!), eight were 2 ways, 1 was first jump on the transition rig (hand deploy and smaller canopy so I pulled high (4000')), and 1 was a tracking practice jump.

$730 and a signed and stamped proficiency card later, I was a licensed skydiver.

I think it should be each individual's decision as to what they deem appropriate for their pull altitude. When I first started jumping it was 3500'. When I started doing multiple ways, we tracked at 4500, that way if I went a little low before tracking, I was still within my comfort zone. On one of my last jumps I did on the manta I made the comment to one of my instructors that either things are slowing down in my mind or it's taking longer and longer for the manta to open. After that comment they put me on the transition rig, which after about 10 jumps, also seemed to get slower and slower openings. For me, when things start to slow down in my mind, that's when I know I can go a little lower to pull because I'll be able to recognize a malfunction earlier, evaluate, react and execute a plan. But any time I downsize or change canopies, I'll increase my pull altitude again until I notice things slowing down again.

I personally think being able to do a hop 'n pop without any worries is very valuable. What if there is an a/c emergency at 2000' or 1500' feet? I know that I can leave stable and pull immediately without any problem. If I was nervous about getting out at 3500' or 4000', I couldn't imagine what would go through my mind if I had to leave at 2000' with an a/c emergency. I think it's more important to be able to do this than having more ff time.

And as for the learning "curve" of AFF vs static line, from what I read on here, AFF is like 8 jumps, then you're signed off to jump by yourself as they try to cram "everything you need to know to jump in 8 jumps", but you still have to fullfill your class A requirements. With static line (aka my experience with static line), is that you're taking one step at a time, and tend to have more instruction. For me, it's easier to learn step by step where one or two things are added, than like in AFF were many things are added to a single jump.

All just my opinion! No, you can't change it. I just just curious on how others, especially instructors, rate/compare/contrast the two.

I think a mix of S/L and AFF is the best way to go. I did straight static line, but I may have picked things up faster if I had competent instructors with me on long delays to assist and observe body position first hand.

I like the flexibility of the ISP in this regard. You can switch disciplines to meet certail learning goals. If your student is having difficulty with canopy control, put them out on low cost static lines with radio assistance. Freefall troubles? Transition to AFF or Tandem.

Our dropzone recently noticed that we were having fewer and fewer people graduate the AFF program. They decided to reintroduce static line at a low price and guess what, a bunch of people signed up for static line jumps. Many decided to transition to AFF after only a couple of S/L jumps, but I believe that having the lower cost option available helped people enter the sport without fear of wasting money.

BTW, I knw a young jumper (~75 jumps) who has never exited an aircraft below 10,000 ft. She is too scared. Not good.

Especially if someone signed off on her A license card.[:/]


As for the original question, I started with SL, and ended up in a bit of a hybrid AFF/SL program because I was having trouble with exit stability on my first 5-second delays. Despite those early challenges, living in the Northwest, I've come to know and love hop & pops and will at times choose to do them even on a nice day. Lowest I've exited is about 2,500 feet - I'd rather get out higher, but I am glad I challenged myself on that day of low clouds - if I ever NEED to get out of the plane that low or lower, it's nice to know I've done it before, by choice.

just wanted to correct you on what aff does. its eight jumps one tandem and seven levels of training after the seventh level you have three solos two from alt. and one hop and pop from 3500 ft, after that you have 12 to 15 coaching jumps, you can not jump with anyone but a coach untill you have 25 jumps and must use the student gear untill you are finished, were i learned they also make you spend 10 min in wind tunnel before your fjc and you also take a packing class and jump a pack job

yea, AFF differs at different DZs.

At mine, it was just 7 lvl's...then as many coached jumps as you need to get your A-license card signed off. Then you can go solo, or with a coach for to get your jump count to 25.

I have been on many loads where break off starts as high as 6,000 feet or higher and some are required to dump below 2500. To do other wise would be unsafe. You pick your gear to match the type of dive you are doing. 1000 foot snivels and twitchy 97 sq. ft. canopies are frowned upon.

On bad weather days we used to practice 10 speed stars from 4500/5000 feet. Exit, dock, track and pull. The whole team would be in the saddle by 2000.
My idea of a fair fight is clubbing baby seals

I wholeheartedly agree. She did not go through her AFF at our dropzone. I don't know where she did it.

She has been strongly encouraged by the staff to do a few hop and pop's, but is resistive. Maybe they should force her to, it is not under my control.

Funny how your thread got hijacked from AFF vs SL into H&Ps and low exits/break-offs/pull altitude....

Bottom line seems to be:
1. Similar costs in the long run
2. Better skills in some areas vs others
My reality and yours are quite different.
I think we're all Bozos on this bus.

popsjumper---IMO, I don't think it got too off topic. The discussion regarding hnp's and pull altitude are related to the differences in AFF and S/L.



Agreed.

I'd be curious if there are any other discussions that could stem from an AFF vs S/L debate.
