7which is too narrow between the karabiners, would provide less feedbackbut also increase any risk of developing a twist in during a large collapse.2.5 SPEED-BARThe speed-bar is a means of temporary acceleration by changing theflow over the profile.The speed system comes pre-installed on the risers and is notmodifiable as it conforms to the measurements and limits stipulated in itscertification.The ARTIK 4 P includes a speed system with maximum travel dependingon its size (see Full speed-bar).The speed system is engaged when the pilot pushes the speed-bar - notincluded as standard with this glider model - with their feet. The pilotmust install and adjust the speed-bar and connect it to the risers (See2.5.1: “Speed system assembly”).The speed system uses an action/reaction system: released, the speed-bar is set to neutral. When the bar is pushed using the feet, the wingaccelerates. The speed can be regulated by varying the pressure on thebar. Once the pressure on the bar is released, the speed system returnsto the neutral setting.The speed system is efficient, sensitive and precise. The pilot can use thesystem whenever they want during the flight. In the neutral position, thewing is flying at standard speed and glide. With full speed-bar, the gliderwill fly at maximum speed but the glide will be worse.• Released speed-bar: the A, B, C, D risers are aligned.• Full speed-bar: the difference between the A - C risers is:Size 21 - 10.5cmSize 23 and 25 - 15cmSize 27 – 14cmPLEASE NOTE!The use of the speed system results in changes to the speed but also thereactions of the wing. For more information, see the certification report.2.5.1 Speed system assembly.The speed-bar consists of the bar that the pilot pushes with their feet, aswell as the two cords that connect it to the speed system componentson the risers. Once the pilot has chosen the type of speed-bar theyprefer, they must install it. Some considerations:• The pilot should use the type of speed-bar that they considerappropriate, depending on the type of harness, preferences, etc.• This accessory is removable to facilitate its connection and / ordisconnection to the risers as well as subsequent adjustment.• It is important to follow the manufacturer’s instructions during thespeed-bar installation. The majority of harnesses have a speed systempre-installed.• The standard connection of the speed-bar to the speed system is viaBrummel hooks, where two slots in the hooks are interlocked, makingtheir connection / disconnection easy. However, any safe connectionsystem can be used.
