We commonly have the 200+ pound newly A licensed jumper searching the classifieds for a rig with 190 main and room for downsizing. The newly A licensed jumper didn't decide on his own it was the right size. Changing the culture would help.

I didn't realize this was such an old thread.

Solar flare activity causing localized gravity storms. Gotta have something for when you funnel a formation.

I'm very interested in the Skylife Vega/Sirius/Orion. I understand you haven't used them, but do you know of their reputation?

A person must realize their situation and apply the right action. There is evaluating and responding going on. Many will see that as synonymous with a decision. Decades worth of evidence supports the ambiguity of the terms. An outsider would conclude new terms would likely work better than a new effort to train better.

It has been asserted there is obviously no decision made at the hard deck. Perhaps that is the source of the argument. If any of us tried to put on paper a hard deck algorithm, there would be diamond shaped decision boxes, correct? You could call them if-then boxes if you want, but a person must do the evaluation of the situation and make the correct thing happen as must be done at decision altitude.

How shall we fix the poor training, by telling the instructors to do it better? How shall we prevent people from giving their decision altitude when asked what their hard deck is? The misunderstanding has existed for as long as the terms have been used. The 3rd post especially shows how this has persisted. The use of these terms is a significant part of the misunderstanding.

If asked "what is your hard deck?" the reply of many will be their decision altitude. If asked for both, the distinction is forced.

Quite right, it isn't obvious when things are ambiguous, which makes it so dangerous. I think the use of the term "decision" in one of the terms, but not the other, because the hard deck doesn't involve a decision or whatever...is awful. Only a committee of overeducated experts could get such a lousy result designing the terminology which ought to be used.

First unit I received made no sound, same as another friend. They were very nice and promptly sent a second unit which worked. Certainly got the impression they replace many. My friend took his apart and found a solder connection of a wire to the speaker was bad.

The definitions should be dropped, new terms used, not revised. The OP showed us very clearly how the confusion has defied efforts at clarification. Let us learn the lesson and stop trying.

I already have one. I understand they are inexpensive and poorly made - bad wiring. Of course I'm looking for a cheap audible. The full feature VOG does nothing of much value extra, in my opinion. Multiple beeps do not a VOG make. Seemed reasonable to ask whether the basic version is actually being delivered.

The use of the terminology hard deck and decision altitude should be avoided. So many convinced of what it obviously should mean but it isn't so obvious.

For those interested in the cheaper version, has anyone actually known someone to have it? All of them seem to be the full feature unit, which is surprising. Are any of the cheaper versions out there?

Even with the best oxygen system, are pilots allowed to fly at those altitudes for only a short time? Doesn't this seem like an obvious question?

Extra "axis" in effect can be put on a chart similar to the attached. A graph could show speed on x-axis, altitude on the y axis, and still have curves on the graph representing different manifold pressures which are the other "axis".

Never needed glue. Did you try inserting the turned-back end into the other end? Doesn't need to be inserted as far as your pics show you doing. A bit bigger in dia than yours, but the overlapped section is shorter and fits at the base of the larkshead well.

For those resistant to using alternatives to rubber bands...have y'all ever had a had to replace a rubber band at a center locking stow location? Did it break while the lines were getting pulled free (no harm if it breaks then) or did it break long before line stretch? When they d-bag is accelerated upwards, when you absolutely do not want a locking stow to break, the Newton's 2nd law force from the hunk of nylon inside is focused on breaking that/those critical center locking stows. where all that force gets concentrated. A substantial portion of nasty hard openings may be due to this. The critical middle locking stows are the only location where I've used tube stows for 30 or so years. It isn't practical to double stow so the bite goes relatively deep. Regular bands do so much better for the outer 2 locking stows on my 4 grommet d-bag and the non-locking stows. The tandem mfgs obviously do not trust regular or even the super wide/thick tandem rubber bands alone for critical locking stows. The risk for the tandems is more severe because of the much heavier mass inside the d-bag, but the point still remains for smaller canopies.

The nose does not have to be oriented toward the side as originally laid down. The nose can be prepared just as when pro-packing, and it can be oriented to the floor as a pro-pack is.

It seems like my instructions are the opposite of the word document. I put the rolled up side into the other. The result is a larger diameter at the junction, which gets placed at the base of the lark's head knot when installed. It is a bit bulky, but doesn't bother me. No need for glue when there is so little tension when installed.

I sprayed/soaked a "F-111" PD210 with Scotchgard. It planed out much better for several years. Doesn't have to be zero porosity for it to be a significant improvement.

The use of ammonia as a carrier of hydrogen fuel for fuel cells is really interesting. The old ways of making ammonia might get a radical upgrade, along with new ways of getting fuel cells to use it more efficiently.

Customer service innovation, increasing their appeal on the used market.

Never had a Sabre, but the original Sabre had the reputation for hard openings, with many experimenting with slider pockets and such. The Sabre II had a reputation for not opening on heading, but did not have the hard opening reputation of the original. I have never heard of the association to the steering lines.
