Introducing the G-chute
Introducing GIN GLIDERS’ G-chute and the G-chute pocket – What is it, how’s it installed and how do you use it?
The GIN GLIDERS G-chute is an easily deployed drag parachute that reduces the g-force that occurs when making a spiral dive to reduce height.
The G-chute enables the pilot to achieve a higher rate of descent with fewer turns and less G-force.

The G-chute is installed in a pocket in the harness, the riser is attached to one of the main hang point carabiners or to a dedicated connection point on the harness and only deployed to use during a spiral dive.
After the spiral, the G-chute can be killed by pulling on the middle line and stored for re-use.
Depending on glider and sink rate, a G-chute can reduce the G-force up to 30%.
The G-chute is particularly effective with high aspect ratio wings and is recommended for pilots who fly with the Genie Race series harness or similar and a competition glider.
The G-chute can be used on any harness and with any glider. Having said that, high aspect ratio gliders profit the most from the G-chute use due to their longer lines and higher resulting forces.
Installing the G-chute
Many competition and XC harnesses like the Genie Race will have a special G-chute pocket, inside which you will normally find a small dedicated maillon to connect your G-chute riser to.
If your harness doesn’t provide a similar dedicated pocket, you can store your G-chute in any suitable pocket of your harness and connect the G-chute to one of the main carabiners of your harness or you can use the optional GIN G-chute pocket shown below. Again, connect the riser of the G-chute to either the left or the right main carabiner.
Flying with the G-chute – Preparation for us
Check the condition of your G-chute and other flying equipment before every flight. Prepare for launch by checking the following:
- Is the G-chute fabric free from tears or other damage?
- Are the lines and net free from knots, tangles or other damage?
- Are the maillons connecting the lines and risers closed and secured?
- Is your G-chute correctly installed in your harness or in the G-chute pocket?
- Will you be able to reach the G-chute handle in flight to kill the chute?
- Make sure the G-chute does not interfere with your rescue at any time
WARNING: Double check that your G-chute can’t under any circumstances interfere with your rescue parachute or your reserve handle.
Pre-deployment, Inflight check:
Check the following before you deploy your G-chute in flight:
- Are you high enough to safely use the G-chute?
- Are there any other aircraft near you that might get too close to you while you descend?
- Only use the G-chute if you are in good physical and mental condition.
Deploying and using the G-chute
- Make sure you are flying straight and level at trim speed.
- Take the G-chute out of the G-chute pocket and release it on the side of the harness that it is connected to.
- Release the G-chute handle so that the chute opens and causes drag.
- Start your spiral dive on the same side to which the G-chute riser is attached. If your G-chute is connected to the left main carabiner, make sure you make the spiral dive to the left and vice-versa.
- Get yourself used to the G-chute. Start with a moderate spiral and adjust it to your needs with the outside brake.
- To exit the spiral, check your weight is centred (or slightly towards the outside) and progressively release the inside brake.
- As the glider starts to exit the spiral, make sure you control any pendulum moment.
- Once you are back in normal flight, kill the G-chute by pulling on the G-chute handle that is connected to the centre line.

You can now put the G-chute back into the pocket for re-use, taking care not to allow the G-chute to re-inflate when stowing.
- Don’t deploy the G-chute if your glider is wet or if there is any other risk that your glider might go into deep stall.
- Don’t make the spiral dive to the opposite side of the G-chute riser attachment.
- Don’t deploy your G-chute in any other flight state other than trim speed in straight and level flight.
- Don’t use the G-chute on the final approach or landing.
Material stress: Even though the G-chute is designed to reduce the G-force, strong spiral dives can cause a lot of stress to your gear.
Final tip: Bent legs and a loose, spread open cocoon enhance the drag effect, reducing speed and the resulting g-force 🙂
