Canopy Body Position

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.
The legs are symmetrical, positioned apart with the knees slightly bent, almost as if you were sitting on a bar stool.
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.
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.
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
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.
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
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.
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?

Ci dirigiamo verso la drop zone di Ravenna con l’entusiasmo alle stelle, chiamo il mio socio Sansi già alle prime ore del mattino, nonostante una pioggia battente.
Arriviamo ed iniziamo subito le presentazioni con Mattia e il Masi. Di corsa in decollo per assaggiare l’aria del “Pull Out”.
Intanto sono arrivati anche altri piloti di Tuta Alare, siamo ormai 15, non rimane che iniziare a formare i gruppi di volo. Cominciamo con un 6 che si rivela una base perfetta, ma per una serie di motivi nei lanci successivi verrà sostituita con difficoltà di rateo verticali considerevoli.
Grazie ad Edward e la sua esperienza del record del mondo a 100, terminiamo la giornata con 4 lanci di allenamento e tante cose nuove imparate.
Ottima cena tutti in compagnia in drop zone con il mitico Lele degno Masterchef!!
Domenica ore 8.30 pronti al 1° decollo per un lancio a 8 con ..mamma li turchi!!
Superato anche questo si parte per il tentativo a 10!! E questo è il lancio giusto!!! Quota di lancio 4200m, cielo limpido, aria fresca ottima visibilità.Chiudiamo in breve tempo una bella base stabile che permetterà la formazione a 10…E’ RECORD!!!!
Grazie a tutto lo staff del Pull Out, Mattia e Masi, ai piloti di Wing Suit partecipanti…Forza ragazzi ci aspetta adesso un nuovo record!!!
