OK, so now try comparing a slow 360 with a fast 360 and level flight for a time so that both take the same overall time. Which costs the most altitude? If you use toggles, then I think that the fast turn will cost more altitude as it induces more drag, and is less efficient. Front risers? Rear Risers? Body position?

Yes, I agree that 10hpa is approximately 300 feet, but that doesn't mean that the AAD will fire at 450 or 1050 feet. It fires at a pressure equal to 750' height above arming altitude. If the unit is 10hpa low, then it reads 1003 hpa at ground level (if the true pressure is 1013) and it fires at a pressure of 1003 less 29hpa, i.e. at very close to 750'. The key here is that absolute accuracy isn't as important as relative accuracy - think of an inaccurate altimeter - you adjust it to zero on takeoff - at 13000 feet it reads 12500 feet - its much more than 10hpa wrong, but at 750 feet its reads 721 feet, not 250 feet.

I don't think this is a correct interpretation. Standard atmosphere pressure is 1013 hPa. Since the Vigil (and other AADs) calibrate themselves when turned on, a 10 hPa error in calibration will only make approximately a 1% difference in level as the AAD is looking for a pressure relative to the pressure at turn on. So while a 10hpa error in absolute pressure reading is of concern, since it indicates something astray in the unit, it does not indicate that it will fire 300 ft away from it's design altitude.

Docked formations: How far can we take this one....

Agreed, I wasn't really thinking of a long rope, but rather a flexible gripper maybe 20cm long with only one end attached. The difference between stupidity and genius is that genius has its limits." -- Albert Einstein -

strop45 replied to mccordia's topic in Wing Suit Flying
How about a different type of dock, e.g. trail a short piece of rope from each leg. This would give somewhere to dock on where you could make small adjustments/movements without disturbing the formation?

If you think para-gear's customer service is so bad, the answer is easy, buy from someone else who has better customer service. That way both you and Para Gear will be happier. Not sure why you have backed yourself into this corner, but don't think you will find many people who read your posts and have any second thoughts about buying from Para Gear, indeed they are actually good endorsements for Para Gear.

Jumper Integrity & Logbook Veracity
strop45 replied to GLIDEANGLE's topic in General Skydiving Discussions
Agreed. My point is that the requirements of 2m don't necessarily assist with off-landings and that maybe requirements for touching down and stopping moving would be more appropriate if the object is to assist jumpers with backyard landings. BTW to the OP question, my answer is that we all lie, the questions are how much, whats at stake and who gains from it. Personally I couldn't see any good reason to fake entries in my logbook, but don't always get them signed, and one day....

Jumper Integrity & Logbook Veracity
strop45 replied to GLIDEANGLE's topic in General Skydiving Discussions
Not disagreeing, but note that its easier to ensure that you don't have to jump at night, than to be sure you will never want to parallel park. I don't really have an issue with the accuracy requirements, but do think that they aren't the complete answer to off-landings. When trying for accuracy, I usually use double front risers to give more speed and a longer plane out. Its then relatively easy to 'touch' down near the spot. Landing out is a different game altogether. From my limited experience, I have found it difficult to judge wind without the usual visual clues and this factor alone makes accuracy more difficult. With a round, clearly the ability to land in a backyard was very important, with a modern canopy it is less so? It seems to me that provided that you make a decision high enough, you will generally find something better than a backyard. Perhaps I'm wrong, how many people have actually landed their modern canopies in backyards? The difference between stupidity and genius is that genius has its limits." -- Albert Einstein -

Agreed, getting down safely without hurting myself or anyone else is no 1 priority. Now at the risk of being flamed, what does 'landed within 2 metres' actually mean? Is that first touch the ground within 2 metres? The difference between stupidity and genius is that genius has its limits." -- Albert Einstein -

looking for the lightest decent stills camera

my understanding is that the short answer is no.

Places to sport jump in New Zealand...

Kia Ora - Skydive Abel Tasman in Motueka, Pudding Hill (near Methven), or Fox Glacier would be my recommendations. Wayne The difference between stupidity and genius is that genius has its limits." -- Albert Einstein -
You were lucky. We lived for three months in a paper bag in a septic tank. We used to have to get up at six in the morning, clean the paper bag, eat a crust of stale bread, go to work down t' mill, fourteen hours a day, week-in week-out, for sixpence a week, and when we got home our Dad would thrash us to sleep wi' his belt.

Thank you for that. Your description and Hellis' picture show the scenario well. One further question, if you are doing a pin check on a low time jumper (say 50 jumps) who packed their rig, do you normally pull the bridle out and trace it from the pin to the PC?

Quote See Here QuoteYip, saw that, don't understand it or see how it can be done. My pin is only about 15mm long. Not sure you you could insert it and leave less than 15mm of slack in the section of bridle from the pin to the D-bag. It seems to me that the section of bridle from the pin top to the PC is the most critical piece. The difference between stupidity and genius is that genius has its limits." -- Albert Einstein

Ok, so a couple of questions: 1) how do you mis-route your bridle so that it causes a container lock? 2) how do you check for this when you are doing a pin check? There has been considerable discussion over these questions in the incidents forum, however there isn't any clear consensus. At least poster replied to question 1) with the way I close my rig every jump. Its worked for the last 400 or so jumps, so I guess I must have luck on my side? Frankly I can't see any easy way you can achieve a container lock without making it extremely obvious(e.g. taking bridle back under flap then over flap to bottom of container.)

So is it or is it NOT your opinion?? Make your mind up. Having more or less experience doesn't alter the fact that its your opinion?? Also having more experience doesn't always make you right.
