I agree. So why doesn't the BSR allow for tandem flybys when permissions are granted and planning is performed? Ah yes, they aren't qualified to make that decision...right? ***I do not believe that tandem students should be subjected to the added risks, and solo students are (IMHO) not qualified to evaluate the risks and requirements of being involved in a close fly-by. Are tandem students qualified to evaluate the risks of having a video flyer present? How about a handcam on the TIs wrist? Why do we allow tandem students to consent to adding some risks to their jump, but not others? What makes a qualified video flyer in proximity to a tandem any different than a qualified wingsuit flyer? The answer, I believe, is that outside video and handcams drive revenues. Money talks. If the USPA applied this rule to any revenue-generating activity the DZs would be up in arms. Wingsuiters however, have a very poor lobby in the USPA. FWIW - I'm not in favor of handcams, but that's a topic for another discussion. Outside video, in addition to its financial and entertainment value to the student, is also very useful as a teaching aide. So we permit it with minimums, qualifications and coordination with the TI. There is (or is intended to be) a very low speed delta between the Tandem and Vidiot. To me (and I'm open to new opinions) this is closer (at least in closure rate) of saying that the vidiot can start out 5 seconds behind and get the dramatic footage as he passes us in an angle dive... Finally, while there are certainly very skilled wings out there, there are also many whose skills are more wishful thinking. (YES I know, the same can be said for vidiots and we do have that problem too... but again, the closure rate is a big difference IMHO) This is proximity flying with a moving target where mistakes endanger the other individuals... and no, I don't think T-students are qualified to make an informed decision to take on that unnecessary risk without benefit to their jump.

The is absolutely no reason that a wingsuiter needs to get within 500ft of anyone under canopy without pre-jump flight-planning and permission from all involved. I do not believe that tandem students should be subjected to the added risks, and solo students are (IMHO) not qualified to evaluate the risks and requirements of being involved in a close fly-by. No offense to birdmen, but I don't like surprises especially when I perceive a risk to my health/well-being. Just my $.02 JW Always remember that some clouds are harder than others...

I am hoping that his posting was along the lines of "You won't believe what I found..." rather than "it'll be fine for a while yet..." JW Always remember that some clouds are harder than others...

Look nice... what (if anything specific) do you wear for your top? JW Always remember that some clouds are harder than others...

So how was that split-tail 5-cell to fly?? Always remember that some clouds are harder than others...

Years ago I asked Ted about the system and he showed me a mock-up of the system, but I got the impression he didn't have anything more than that on hand. PM me if/when you get the risers, I'd like to see the complete functional set. JW Always remember that some clouds are harder than others...

Other's will have better answers than I... my largest being 6'x10', but I have picked up a few points that my be useful... The weight I needed varied quite a bit based on: - flag/fabric type and construction... both varied the amount of drag the weight had to overcome. (the weight of the flag itself helps, but usually at a greater cost in drag). - canopy speed changes the equation a lot as well. The higher the speed, the greater the weight needed to keep the same/equivalent suspended angle/bow. A final note given me about big flag (haven't had the chance to test this yet...) many report that the big flags fly much better/straighter when the weigh is integrated along the leading edge (think a multi-compartment tube of lead shot sewn to that edge) rather than a large weight at the bottom. As always, flying flags is a completely different type of canopy flight and should be treated as its own discipline with all the thought/consideration and focus on the new safety issues that come with it.

For myself, I got the Strong rating because at the time there really were only two options (Strong and Vector) and RWS/UPT required that you have an instructor (SL or AFF) rating prior to taking the TI course. Having none, and no real desire for either, I went the Strong route. I did however have to take the BIC (for those that remember it), as it was a new requirement. But got the brand new USPA TI rating when the Strong TI was completed. JW Always remember that some clouds are harder than others...

With apologies to the OP, this was too good a question to leave floundering with what quickly became apparent as too limited a list of options... So, what ratings do you hold? In the comments it would also be interesting to know: What do you actively use? Is the choice of what ratings dictated by where you work, or do you choose where to work based on the ratings you have/rigs you like? Did I miss a brand?... yep, likely... don't know them all, but this might give a better representation.

D@MNN!!! Moderator - please kill this thread. I swear I configured it for multiple options, but it didn't take. I'll repost as such, but this one needs to die. JW Always remember that some clouds are harder than others...

I'd rather pack a round than a ram-air reserve any day... JW Always remember that some clouds are harder than others...

Again, that depends on what is going on before the jump... I've spent 30min all under 1000' on a scenic flight. If the pilot is burning to get you up for a jump (as mine did), no problem. But a scenic flight with a jump a the end could be a real problem. Just sayin', JW Always remember that some clouds are harder than others...

And on a typical day at the DZ (where the LZ is in the same location) this "set-it and forget-it" approach works well for 99% of the people 99% of the time. But like anything new(er than Terry ) you must know more about them than just that, or the 1% of the time will catch you. (and I'm as potentially guilty as the next well-informed guy... glad the OP started this discussion...) Unfortunately, each electronic altimeter type device will have its own auto-zero behavior and thresholds. Since its what most of you have on your rig... anyone know (without looking) how the Cypres-2 knows if its to be in 'on-a-jump' mode??

Wow, thanks for that. Another reason I'll stick to analog. Me and Jerry may be the last ones. One of the reasons I still have a chest-mount analog... I just wish they read the same in freefall... (same in the plane, same under canopy and on the ground, but 1k' different in ff ) JW Always remember that some clouds are harder than others...

You too will cross the threshold into old age. Best of luck when you get there, Jerry Baumchen “Old age, in short…One day, perhaps, it will happen to you…if you are lucky….” As to the original question - yes, a digital altimeter (audio/visual/AAD) could be susceptible to thinking it is still (or back) on the ground with a simple barometric change. Hold an any one altitude long enough and I suspect all of them would unless/until they determine that they are in flight mode (for those that do). Climb slow enough and it may not get to that mode either. BUT, the behavior/thresholds are going to be different based on the programming of each brand/make/model/update-rev. (at which point anecdotal discussion will not give you your best answers) If you are concerned about your specific equipment, ask the manufacturer about it and what climb/hold parameters would be a problem. If you're going for a balloon jump and the pilots climbs out smartly and simply ascends til jump time, there should be no problem. If you're going for a long balloon flight/excursion with a jump at the end, then you may have issues. For your visual altimeter, I would read up on whether you can readjust it in flight. If so, check against the balloon pilot's alt. You could also borrow an analog alt from the local DZ as backup... My bigger concern would be to ensure my AAD behavior was compatible with the intended flight profile. (should be, but check) They're a lot of fun, wish I was going.

Yep... very different situation than your initial post implied. JW Always remember that some clouds are harder than others...

But if, as seems to be normal in the US, you only have 4-6 hours on one day before your first AFF/SL jump, there is only so much a student can be expected to absorb during the class. Each approach has its advantages, but with the choice on class length comes choices as to what the student can be expected to remember. JW Always remember that some clouds are harder than others...

Um... no. Is stupid and reckless. JW Always remember that some clouds are harder than others...

Even this commonly accepted technique fails to include the most critical data of all - the difference in wind speed and direction between the exit altitude and the planned deployment altitude. Agreed... hence the caviot that its "the best method we have so far"... This is where (in addition to looking/paying attention) the feed-back loop is essential... jumpers both on the ground and in the air should note how well things are working and get the next load to adjust their spot/jump-run/timing/etc... to get the necessary location and separation. Its bad enough when one load has issues, repeating it on the next (few) is just wrong. JW Always remember that some clouds are harder than others...

You don't use it because it doesn't work? Or just doesn't work as well as counting? Also, "usually" means there are cases where at least one person does not use the counting method. What method does that person use? Mark The 45degree method (which I was taught when I started) has been mathematically, computationally and empirically proven not to work. The person who does not count, is relying upon past experience and luck to given them the separation we need. The best method we have so far seems to be a GPS derived ground speed on jump run, separation count chart with notations for larger groups/higher breakoff with longer tracks, and a calm/reliable count. Note: if you are counting and THEN starting your climb-out, u're doin' it wrong. The full separation count should INCLUDE your climb-out and exit count time. If you're the last out, whatever... but in the middle of a large plane this can be an issue. JW Always remember that some clouds are harder than others...

Agreed, I think it is secure. Though to the OP... in the shadow it is hard to tell directly. JW Always remember that some clouds are harder than others...

Follow on question here... For those that say (on this, or ANY other issue) that "its the rigger's job".... have you discussed with YOUR rigger what (s)he does consider their job? _I_ do inspect/clean/lubricate the cutaway cables and exercise the main risers, if they are present... but several folks bring their system to me without the main and/or cutaway cable there... Other riggers feel that they are working on the TSO'ed portions only (not the main) unless specifically asked because, that's the owner/operator's job... Want to know what your rigger does? ASK?!?
