humanflite 0 #76 April 17, 2012 QuoteQuotethis the same guy?? Thanks for posting that link, it's a fun video. I always get a kick out of newbies who jump out of the plane and then check their altimeter 2 seconds out of the door. News flash pal, you're 100 ft lower than when you jumped 2 seconds ago. It's also fun to watch the rapid-fire alti checks right down to pull altitude. I guess if you can't figure out that you have a few sconds and then pull, you could just 'lock on' to the thing and wait for your pull altitude to come up, but I'll never understand the need to look, turn it away, look again, turn it away, look again, turn it away, and then pull. Beyond that, if a simple brake fire is going to force the guy to chop and dump his reserve on his back, he has no business jumping a Velo. Of course, having 300 jumps, and lying to the DZO is aslo a good sign he might be in over his head. Bit of a stupid thing to be suggesting that he shouldn't have cut away from a 'simple' brake fire.. He didnt have a great deal of height left and under a spining main (regardless off why the spin was caused), armchair quarterbacking his decision will lead other newish jumpers to think 'well Im not meant to chop a brakefire or I will get teased'... Even if he had cleared the other brake the canopy might have been spinning too hard with twists to salvage it before he impacted the ground. So I say he made totally the right decision as he walked away from it. Whether he will walk away from jumping a velo at 2:1 with 300 jumps.... maybe for a while. But as has been said his bell is gonna get rung for sure. Quote Share this post Link to post Share on other sites

Joellercoaster 6 #79 April 17, 2012 I'm late to the party, but: great job. It can be hard to do the right thing when the tone of the criticism is so harsh, most people get defensive. But the tone is harsh because the realities are harsh, and the critics have seen them first hand. It must be even harder to come on here and say that, and I salute you for doing it.

Quote Yes. Some do. Personally, I don't use a mental "clock". I use my eyeballs. I learned that on my first 5-second delay when the 5 seconds I counted turned out to be 11 seconds that the JM counted. I was addressing the youngsters who may not have yet developed that situational awareness. Two different situations and so I stand by my post. Yes, doing these things will help them get to the point that you and I have already reached. In this thread we are dealing with a guy that is supposed to be beyond student status yet shows, by his decision-making, that he is not as far beyond as he thinks he is. Just like EP's, you should have those altitudes engrained in your brain before you get on the plane. Talk to an instructor if you don't know when to bail out and when to stay with the plane. Quote Yes. You should. Note that I said "reasonable". Instruction on the ground is one thing. Telling them how the parachute is going to act on a quick deployment after bail-out is one thing. Actually doing it is another. Personally, I consider that threshold to be a personal thing and is different to different people. What my threshold is may be, and quite likely is, different than yours. So how does a young jumper determine what is "reasonable" for him and his comfort level...they jump, they check their altitude loss on exit and SEE how much altitude they lose before they pull and SEE how much altitude is lost for opening. Now they have a real point of reference to determine their own personal threshold. You've seen it. You've seen posts here about it. "I'm gonna dump my reserve because my main takes 800 feet to open!" You and I know that doesn't happen on a bail-out with a throw right out the door. Checking their altitude on that exit will SHOW them the reality of the opening process on a quick deployment. THAT will help them set their own "reasonable" threshold. And being too altimeter dependent is UNCOOL and dangerous. Key word "too". Yes. For God's sake we don't want eyes locked on the alti from exit to pull time! Again, I am talking young jumpers here. What you are addressing is situational awareness as related to altitude. Youngsters don't have it so what to they have to help in developing it? The altimeter. Yes, we all want them to develop that sense. We want them to train their eyeballs. But yes, until they do, the altimeter is all they have...and yes, it a a tool to help them learn as well as a life-saving instrument. If it takes checking an alti every two seconds for one to maintain awareness, then so be it and good on you! I've watched more than one jumper take it down too low with a broken alti. I hear of people "missing the beeps" on their audibles. Hey, the ground is there on every jump. Don't be surprised when it comes up at you. Yep...and I've seen many, many more "take it down too low" by losing altitude awareness using (not using) altimeters of whatever sort. Thanks, John for you comments. You are correct for experienced people. The guy in the thread isn't as experienced as he thinks he is. To all: Sorry for the hijack. Altitude awareness was mentioned and I felt it import to provide some info for the youngsters. Let's all get back to the topic at hand, eh?My reality and yours are quite different.

And for the first five seconds you are for all practical purposes in a vacuum because the air does not affect the acceleration profile until that point. See the attached chart that shows what I mean; as soon as you hit five seconds (about 85mph), your rate of acceleration drops off significantly as air resistance becomes a factor, and by the time you get to seconds 8-12, you're only accelerating about 4 feet per second per second. The "vacuum formula" does work for the first five seconds, though, especially if, unlike Dave and me, you can do basic math. 44 SCR-6933 / SCS-3463 / D-5533 / BASE 44 / CCS-37 / 82d Airborne (Ret.)
