Delivery
Every ADVANCE paraglider has to be flown by the dealer before delivery to check for correct settings and trim. The dealer finally enters the date of the first flight on the type placard fastened on a rib at the centre of the wing. This entry confirms that defects in the product that can be attributed to manufacturing faults are covered by the ADVANCE warranty. Register your new ADVANCE product in your MyADVANCE account no later than 10 days after purchase to benefit from the extended ADVANCE warranty. More information under "Warranty".
Scope of delivery
The delivery of the SIGMA 12 DLS includes a COMPRESSBAG DLS, a repair kit, a mini-windsock and a «Getting Started» booklet.
Basic settings
At delivery the basic set-up of the SIGMA 12 DLS will be the trim settings that the ADVANCE test team found to be best. Certification was also gained in this condition. Any alterations or changes to the paraglider, such as altering the line lengths or fitting different risers or quicklinks, will result in a loss of the glider’s certification.
Adjusting the brake lines
Leave the SIGMA 12 DLS in its factory settings. The brake line lengths have been set for optimal handling, as established by our test team. The free travel of the brake lines makes sure that the trailing edge remains unbraked during takeoff, in fully accelerated flight and when using the C handles.
Speed system
Speed Performance Indicator (SPI)
Optimal cross country glide between two thermals requires an ongoing choice of glider speed as a function of current headwind component, expected next climb quality and the influence of sinking air. The SIGMA 12 DLS speed (accelerator) system has a Speed Performance Indicator (SPI) which helps the pilot make this choice of ideal speed-to-fly. Three positions are indicated on the back of the rear risers: neutral/0 %, 50 % and 100 %. Depending on the relevant parameters the chosen SPI position can be accurately set. Red tabs on the front risers indicate the selected position relative to the SPI markings.
Each of the SIGMA 12 DLS SPI positions has an icon with a value for headwind, expected climb and sink rate. These indicated positions are effective for only one of their three values, taken in isolation – considered by itself. This means that either the headwind, or the expected rate of climb, or the sink rate applies to that position. The SPI principle is based on the simple (using headwind and sink) and the extended (including expected climb rate) McCready Speed-To-Fly theory
Setting up the speed system
The Speed Performance Indicator (SPI) gives you an indication of the relationship between your accelerator range and your wing’s polar curve, and it also indicates whether your speedbar/loop application is symmetrical. It also helps you set up your speed system. Set the length of your speed lines so that you can use the full travel of the speed system, and that the red indicator shows 100% when the second rung of the speedbar/loop is fully extended. This setting should mean that the first rung reaches approximately the 50% position.
