Un buon materiale per il Freefly deve…
Articolo tratto da Parachutist marzo 2015
So you’ve decided to delve into therealm of freeflying, but you’ve bought a used rig that’s just a tadbig on you and one main-riser cover always opens during exit. Are those things a big deal?
Probably. Can they be fixed? Maybe. Will you have to buy a whole new setup? Not likely.
Let’s take a look at a couple of things toconsider before subjecting your body to the possibility of a premature opening at 150 mph.

Canopy Body Position
Words by: Brian VacherMon, 16 Sep 2013 at 8:19PM
Canopy body position correct
In all skydiving disciplines such as formation skydiving and freeflying there is a neutral body position that we always return to. This neutral body position is adopted and taught for good reasons - to be in control, to be safe and as a start and finish point for more advanced manoeuvres. There is also a neutral body position when flying a canopy.
Lower Body
Correct Position
The legs are symmetrical, positioned apart with the knees slightly bent, almost as if you were sitting on a bar stool.
Why?
This lower body position is essential for safety. The legs should be held similar to the position someone would adopt if jumping from a table to the ground. The legs would be slightly bent supporting our weight evenly.
This means we are ready for the approaching ground – ready to stand, walk or run. This lower body position also means we are ready to go immediately into a PLF (Parachute Landing Fall) if needed.
Secondly this lower body position is essential to know that the body is symmetrical in the harness and therefore not inducing a harness or body turn.
Often people complain of canopies ‘not flying straight’ and do not realise that an asymmetrical position in the harness will have a turning effect on a canopy.
The third and the best reason is that this lower body position differentiates a canopy pilot from a parachutist. A canopy pilot flies with the whole body. With this balanced, legs apart, slightly seated position the canopy pilot is using the body to actively fly the canopy. We are moving to what we call ‘Active Piloting’. The pilot understands the importance of learning and developing harness inputs and flying with the whole body. This neutral body position means the body is ready to make small corrections, to actively fly the canopy safely or to perform aggressive turns with a very efficient input.
Technique
To help to achieve this body position try to shift your leg straps a little lower after opening. Ensure at first you have a good canopy above your head as normal and any problems or nuisance factors are cleared. Do not loosen off the leg strap itself. In addition, if you feel comfortable, loosen (but do not remove) your chest strap to increase the effectiveness of the harness.
Loosening your chest strap also means that your centre of gravity can be forward for landing. This is naturally an easier position for landing as when walking or running your centre of gravity is normally to the front. A tight chest strap can restrict the centre of gravity and keeps it further back on landing.
Incorrect leg position 1:”Ankles crossed”
This ‘undercarriage up’ leg position is not ready for landing. It also means that the body inputs are switched off and encourages an asymmetrical seated position in the harness.
Incorrect leg position 2
One leg in front
This position is very dangerous if you misjudge your altitude when landing with one leg out in front. It can also be a pretty aggressive harness input causing the canopy to turn.
Incorrect leg position 3
Wide legs
This position is again not one that is ready for landing. Having long legs also encourages a person to reach out to the side with a leg on landing instead of trying to fly through the flare for as long as possible.
Upper Body
Correct Position
After checking your canopy and taking the toggles as normal in the hands, the neutral upper body position is to grip the rear risers as high as comfortable whilst the toggles remain in the hands. The hand position should not be full reach or too short above the 3-rings, but as high up the risers as feels comfortable. This will depend on personal preference. The grip is relaxed but firm – grasp around the rear risers as if you were shaking hands with someone. Be careful not to be pulling on the risers. Remember a relaxed grip!
Good arm position
Why?
This neutral upper body position - gripping the risers with the toggles in the hand - is essential to know that the canopy is flying on full drive and that we are not unknowingly deflecting the tail, even slightly, on either side of the wing with the toggles.
This hand position gripping the rear risers also helps the pilot to perform an even flare. Hands that are not gripping the rear risers are ‘wavy’ hands, making it more likely that an uneven flare will occur or that we have to adjust the flare during the landing process.
Finally a very important reason to fly with your toggles in your hands whilst gripping the rear risers is that we now have our hands on our controls. Similar to thinking of the ‘ten to two’ position on the steering wheel whilst driving a car, with this neutral body position we are ready to react and make inputs.
Incorrect arms: Riding the clutch
Incorrect Hand Position
Riding the Clutch
Wavy hands can put unwanted inefficient inputs into the tail, which then need to be corrected. This is similar to riding the clutch in a car.
Thank You
Summary
As with all disciplines when we start from a neutral body position our performance improves and we become more confident. Adopting the correct, comfortable and relaxed neutral body position under canopy, the pilot begins to feel how the canopy is truly flying.
The pilot is able to fly positively and actively instead of trying to steer and correct the canopy reactively to subconscious inputs. This body position should be flown from opening to landing whenever you are not making a specific input into the canopy. Think of your body position under the canopy and ask yourself these questions:
1) How do I look under my canopy?
2) Do I look like a parachutist or a pilot?

Paracadutista atterra “senza aprire” il paracadute 2012
Evento indimenticabile del 2012, che segna un punto importante per il paracadutismo.
A dom.14 ott il nuovo tentativo record per Felix Baumgartner
Tutto rimandato a domenica 14 ottobre come sempre presso l’aeroporto Roswell-USA.
Born in Salzburg, Austria in 1969, Felix began skydiving at the age of 16 and polished his skills as part of the Austrian military’s demonstration and competition team. In 1988, he began performing skydiving exhibitions for Red Bull. The company’s out-of-the-box thinking and Felix’s adventurous spirit clicked, and they’ve collaborated ever since.
By the 1990s, Felix felt that he’d gone as far as he could with traditional skydiving, so he extended his canopy skills with BASE jumping - parachuting from a fixed object or landform. He finds that the lightning-fast reflexes and precise techniques required by such low-altitude feats also enhance his high-altitude skydiving technique.
Felix has made world-record BASE jumps and has been nominated for a World Sports Award and two categories in the NEA Extreme Sports Awards. He is also a prominent advocate for the nonprofit Wings for Life Spinal Cord Research Foundation. And, while he acknowledges that the Red Bull Stratos mission is a step into the unknown, his determination to reach the edge of space and break the speed of sound is unshakable. “If Red Bull Stratos is successful, we can share data that hasn’t been available ever before,” Felix states. “I would be proud to be able to make such a contribution.”

Below is some helpful information about your skydiving rig and how to make it last.
* Familiarize yourself with the location and shape of your main pilot chute, cutaway and reserve handles on the ground. These handles might be in slightly different places than the rigs you used during student status because the rig was custom-made to fit you.
Paracadutismo grandi progetti
Nel 2012 si sta vivendo un momento di grandi progetti nel paracadutismo, con 2 progetti simultanei sposorizzati da una lato da Red Bull e dall’altro da grandi Enti Spaziali Europei con il Freefly Astronaut Project, visibile su Facebook.
Felix Baumgartner e Olav Zipser i 2 protagonisti con l’obiettivo di oltrepassare il record attuale di quota di lancio di circa 33.000 m stabilito negli anni 60, il record di velocità massima di un uomo in caduta libera arrivando a circa 1000km/h
Insomma tanto impegno porteranno di certo a scoprire nuovi orizzonti per il ns. meraviglioso sport: Il paracadutismo!!!

Dopo l’apertura del paracadute
Effettuati i controlli accertarsi che la vs. vela sia idonea per un atterraggio in tutta sicurezza, è necessario essere sicuri che la direzione di volo che ci porterà all’atterraggio, non interferisca con la “zona di apertura” dei parà in decollo con noi.
Approfondiamo: l’aero lancerà i vari gruppi in aereo, AFF-Tandem-FCL-Free fly-etc., con un distacco tra di loro determinato da una serie di parametri: velocità dell’aereo, vento in quota, differenza di volo delle varie specialità in caduta libera. Comunque in media il distacco è tra i 5/10 secondi, anche se in condizioni particolari aumenta.
Se prendiamo in esame il numero di gruppi, la media nel Pilatus è intorno ai 3/5 .
Moltiplicando la differenza media di 8 secondi di distacco per 5 uscite , otteniamo che se il primo ad aprire è paracadutista con poca esperienza , si troverà a vela aperta a 1400m ,dopo circa 50 secondi di caduta libera, l’ultimo ad uscire ha da poco lasciato il Pilatus. A questo punto se l’allievo si dirige verso il punto di apertura dell’ultimo si può creare una situazione di pericolo, perchè nei circa 40 secondi di volo l’allievo può anche percorrere la distanza che lo separa da questa “zona di apertura”.
Allora sarà sempre una buona regola dopo l’apertura dirigersi appena possibile a 90° rispetto la direzione dell’asse di lancio, possibilmente sopravvento, finchè gli altri paracadutisti dopo di noi non hanno aperto i loro paracadute.
All’interno del mio Manuale del Corso AFF potete anche visionare un semplice schema forse più chiaro delle sole parole, rivolgetevi comunque ai vostri istruttori per approfondire l’argomento.

Paracadutismo Sportivo:2 record in Caduta Libera
Nel fine settimana del 8-9 ottobre c.a. presso il “Centro di Paracadutismo Skydivetoscana Arezzo”
Marco Arrigo e i partecipanti al Progetto Phonix hanno raggiunto il loro obiettivo.
In una splendida giornata di sole con vento moderato è stato possibile stabilire il nuovo Record Nazionale imbattuto da 11 anni. Il precedente era stato stabilito ad Udine nel 2000 con 48 elementi.
Come dice lo stesso Marco Arrigo ” con 58 elementi , di cui 22 alla prima esperienza di grandi formazione si notava subito l’energia giusta per il grande risultato.
Si inizia a volare a bordo dei 4 aerei disponibili: 1 Skyvan “Nemo” da 24 parà, 1 Turbofinist da 10 e 2 Pilatus “Tigro e MIke Bravo” anche loro da 10 posti ognuno, pilotati da Marco Carrara, Peter, Ilario De Marchi e Christian Ascani che nonostante l’arduo compito sono riusciti a volare sempre in formazione perfetta.
Al primo tentativo si realizza una formazione a 46, ma si percepisce la possibilità del record.
Insieme ai 4 operatori video per ripendere l’evento dopo le prove a terra si procede al 2° lancio che si chiude con lo stesso risultato del primo.
“ Al terzo tentativo”,aggiunge Marco, “nella prima fase la base, formata con 6 Centrali e 12 Zipper ha qualche problema di livello.
Potrebbe dipendere dalle entrate degli Esterni, ma …..improvvisamente la grande “figura” si stabilizza con l’arrivo degli ultimi paracadutistii.” E’il Record!!Rimane solo Roberto Marroco come operatore video, in quanto i posti degli altri operatori sono stati occupati da altri paracadutisti per il nuovo tentativo di record! Fantastico la formazione si forma in modo omogeneo e arriva il 2° record del giorno…53!!!
Grande festa tanta emozione e si pensa già al nuovo traguardo….100 paracadutisti!!
