In addition, it is very beneficial to be able to turn your head left and right without losing balance before attempting this drill. To practice this, get in a head-up position and focus on maintaining heading while isolating your head movements from your torso. Imagine balancing a book on your head while looking at landmarks near the horizon.
The arm motions required to perform a heading change while upright are similar to those used to make an advanced arm turn (mantis position) on your belly, as the relative wind strikes your flight surfaces from the same angle. The main difference is that the position of the arms relative to the torso is wider (to prevent your legs from burbling your arms).
The elbows remain in a static position relative to the shoulders as you move your hands and forearms up and down in opposite directions. As the forearms pivot around the elbows, you will create a noticeable pressure difference. You’ll deflect the relative wind in such a way that your body will turn in the direction of your high hand. As you turn, attempt to look over your shoulder, not under your armpit, which will help keep your spine straight.
You can apply these arm motions to a variety of head-up postures (see “Foundations of Flight—Head-Up Variations,” December 2012 Parachutist).
Do not attempt to turn with your upper body by banking your arms as if you were in the belly “boxman” position. This will result in your body rolling on its side, similar to a cartwheel. Instead, keep your spine straight and use your forearms like rudders. If the combined motion of both arms is too difficult at first, try the move using only one arm, but anticipate a very slow response.

On October 23, Advanced Aerospace Designs issued reminders of approaching deadlines for compliance with its last two service bulletins.
PIA released Service Bulletin PSB-10092020 affecting after-market tandem main risers constructed with obsolete RW2 rings. All sport tandem main risers produced with RW2 rings, or equivalent sized rings, are affected regardless of the hardware manufacturer, the date of manufacture, the material type or the forging process used. This PSB does not affect "solo" main risers that use RW2 rings. Compliance is MANDATORY – REPLACE BEFORE THE NEXT JUMP.
The FAA is adopting a new airworthiness directive (AD) for certain Uninsured United Parachute Technologies, LLC (UPT) parachutes. This AD results from reserve pin covers (RPCs) catching on the parachute container flaps and preventing the reserve parachute from deploying. This AD requires modifying the RPC before the next parachute jump and replacing the RPC at the next reserve parachute packing. The FAA is issuing this AD to address the unsafe condition on these products.
It’s no secret that more and more people are turning to giving gifts of experiences instead of material things.
Strong Enterprises issued Service Bulletin #35 mandating inspection of the 3-ring attachment on tandem drogues manufactured between June 22, 2020, and February 2, 2021 whose last three digits of the serial numbers between 625 and 714. Status is MANDATORY. Compliance is IMMEDIATE – before the next jump.
