fuck it, I'll swoop around the guy.

That's probably what Jessica Edgington thought....

I highly doubt it for two reasons:

1. I respect Jessica's decision-making
2. If she had seen the low canopy she certainly had the skills to avoid it.

The message to the OP is right .... learn from this experience. It is extremely important.

What is an ideal turn?

I'd say that would be the one that allows you to carry maximum speed through the gate, and with maximum accuracy.

Quote

So why do some pilots use a 630 or 810 degree turn from as high as 2000 feet?

I don't know the answer to that? Could you explain it?

Quote

I disagree that bigger turns make it harder to hit gates. To the contrary a bigger turn allows more opportunity to adjust and can be more accurate than a smaller turn.

The bigger turn also means that you are more subject to drift and may HAVE to adjust. Adjustment is something that you are doing to correct something that has deviated from the ideal, and is therefore performance-sapping.

I should re-iterate that I am not posting the above as fact, merely as my understanding of the situation.

My understanding of this (as very much an amateur) is that the ideal turn is one which builds steadily to canopy terminal velocity.

The turn is used to change the angle of the lift vector as far away from vertical as possible so that it is reducing that terminal velocity as much as possible.

Bigger turns make for harder accuracy when trying to hit gates and are, therefore, a necessary evil rather than a desired part of the swoop.

If the above is correct then the "reverse turn" fails in that it does not steadily build vertical velocity as when the turn direction is reversed, the canopy will start to recover and some element of the dive will be lost.

It may be that in the hands of a pilot who is not experience in bigger turns, the easier accuracy of two smaller turns tacked together outweighs the disadvantage in gaining speed.

Just my thoughts on the subject. I'd like to hear from someone who teaches CP.

Ian? Brian?

Doesn't sound like it is posted in the right forum.

Consistently being that far in the corner would likely earn a yellow card in competition, and possibly a red card if not rectified.

USPA U.S. National Canopy Piloting Championships Competition Rules

The first safety violation by a competitor will result in an YC from the Chief Judge to that competitor. YCs will be issued in general for unsafe actions, lack of sufficient canopy control or erratic canopy handling.

Now, why would I (or you) care for RSL saves.
What would be the difference in skydivng world without all those - saved by RSL?

This is a General discussion thread, try not to bother us with emotional response... please

Drunk post? Or sober and badly worded?

I don't understand the question.

I believe the correct name for the fasteners on the slider is "Hoppen poppers".

planform, aspect ratio

That is not borne out by PD's website which states that the aspect ratio is exactly the same.

Is anyone else having a hard time getting to the message in these videos?

I am not sure what I am supposed to have learned from them.

Any thoughts?

You're not ready for your 100th jump. You need to get at least 500 more jumps experience before you are ready for your 100th.




(good luck & enjoy)

... while kicking out of the line twist he untwisted the suspension lines but put the twist into the risers. but good job by him of landing it uninjured

That's quite an accepted technique. In theory it allows the canopy to spread more and fly giving you more control and potentially releasing the trapped brake lines.

In theory, again, bringing the twists down to the risers allows the spread canopy to pull the risers apart much more effectively than the jumper can do from below so if he had let go and got small he may have simply spun and unwound the line twists.

However, I don't suppose he wanted to try letting go and seeing what would happen as he was trying to land the canopy by that stage.

Using capital letters to start sentences is cool.
Maybe you could start with that?

If you're considering a JVX you should skip the Katana and go straight for a Velocity for 20-30 jumps then, when you're experienced with a cross-brace, get a Valkyrie.

If you insist on a Katana, please get a very small one.

Hi every one, i'm buying a new canopy and a can't decide if should buy Icarus Safire 169 2 or a PD Pulse 170... any info?

Stay safe

It's all down to personal taste; fly before you buy.

Assuming downsizing is actually what you should do (for whatever values of "should"), definitely demo a Pilot 150. I am about the same weight as you and felt like the difference from a 168 was dramatic (more so than 188 to 168 had been).

Try a Safire2 149 and Sabre2 150 as well - they all fly and land a bit differently; now that you have some jumps, your feeling for the differences will have evolved and so might your taste (or it might not - I started on a Pilot and still have one in my second rig, it's on its second reline ).

This is the sensible answer.

Beg, borrow or steal different models to try. Nobody (not even the internet people) can tell you what you will like the best so jump everything appropriate to your skill level that you can lay your hands on.

You are missing the point. It has nothing to do with jumper size/wing-loading.

The USPA SIM (Section 5-3) says:

Quote

Any parachute 150 square feet or smaller is considered a high-performance parachute and falls into the D license guideline regardless of the wing loading.

The OPs question was (quite reasonably):

Quote

Could someone help me understand why canopies of 150 square feet or less are deemed high performance?

The intent of the SIM is quite clear that it is not WL dependent.

I think the sensible way to start this discussion is to define exactly what "high performance" means, otherwise we are talking about something that is open to interpretation.

There are a number of things that, IMO, go into "high performance":

- high altitude lost in a turn
- high rate of turn
- steep glide angle
- high speed at full flight
- high stall speed

The above list is not exhaustive, but all the listed parameters make for a canopy that is less forgiving of mistakes and takes more skill & finesse to fly and land safely in all conditions and over a significant number of jumps.

Many of these parameters also increase with a decrease of canopy size. Therefore, for a given canopy model and jumper, a smaller wing will be higher performance.

Why 150sq ft?
That seems to me to be an arbitrary size because not all 150s will behave equally. For example, a Stiletto would have higher turn rate than a Sabre2 150, but would lose less altitude in a turn.

150 sq ft was probably chosen for the SIM as being canopy that the USPA don't want low experience jumpers using, regardless of their weight.

I do have to ask, if you all think this method is so superior then why don't we see it on student gear.

I don't know for sure, but possibly because of the fear of a dropped pud (a fear which IMO is way overplayed).

A system that is superior, or higher performance in some way does not necessarily make for a better student equipment choice.

For example, collapsible PCs are frequently omitted from student gear because there is one less thing to go wrong.

For the rings, yes you want them below slinks on the risers.

I think (hope) you meant below the toggles?

There is a concern that if you don't pull the rings right down to the bottom of the risers, they could interfere with the operation of the toggles.

OK then.

Pull-out solves a problem that doesn't exit. Use an appropriately short closing loop, ensure your bridle is protected, don't pack your PC in a way that allows slack to work it's way out.

In other words, do a bunch of things that aren't necessary with a PO?

Don't forget inspect and maintain your BOC, pack your PC so it doesn't bunch up in the pouch and don't sit in the plane so your PC can work its way out of the pouch.

I understand that people have their own preferences, but to say that POs only solve problems that don't exist is just burying your head in the sand.

****** That would be the one that gives you an out of sequence deployment every time.

That same out of sequence deployment that reserves use, right?

i wasnt aware that pull-out's also used a compressed spring.. i should probably check with my rigger!



You're right, it is slightly more reliable than the reserve system in that you physically place the PC in the airstream instead of hoping that a spring launches it out of your burble.

That would be the one that gives you an out of sequence deployment every time.

That same out of sequence deployment that reserves use, right?

It's not out of sequence in the sense that with a PO that is the intended sequence.

When I was researching with a view to swapping to pull out, the biggest downside appeared to be more strength required and increased shoulder injury.

With more than 5000 pull out jumps under my belt, I would suggest that anyone having the above problems should change their techniques.

I agree. This problem seems to stem from people using a throw-out type motion with a pull-out system (ie. straight arm pull out to the side all from the shoulder).

The technique I use is as follows:

1. Reach back and grasp the pud firmly
2. Extend the elbow, thus moving the hand down directly towards the feet (ie. NOT out to the side)
3. Feel the pin release.
4. Now that the container is open and the PC is free, move the PC out to the side into the air stream with a straight arm.
5. Release the handle promptly as the PC will inflate and rip the pud from your hand (vs. a TO where the PC will not inflate).

The above procedure means that all the force to free the pud and open the container comes from triceps contraction/elbow extension and probably places less force on the shoulder than a throw-out..

Why not start with an RS (which also offers some tangible benefits with a Katana) and then leave the full RDS for when you are ready to go x-braced?

I assume that's the eventual goal as full RDS is pretty much a balls-out CP thing.

Just a thought.
