Stane Krajnc founded Atair in 1992 together with his wife Magdalena.Over the past 15 years Atair has manufactured thousands of parachutes that have been sold all over the world. Many of the canopies were sold under different names through private labeling (Alpha, Impulse, Cobalt etc.). Now all of the Atair product line is available directly from the Atair website and also via our dealer network.
The long and productive career of Stane Krajnc is one of aviation's most interesting stories. His legacy as a designer extends all the way from hang-gliders in the early 70's, paragliders in the late 80's, to high performance skydiving and BASE canopies from the 90's up until the present day. Perhaps more amazing is the fact that Stane is a self-taught engineer who learned the art and science of glider and parachute design through sheer aptitude combined with 30 years of flying experience.
Stane is not only an expert BASE jumper, paraglider and hang glider pilot, but is also active in many other adventure activities including: rock climbing, kayaking and snowboarding.
Atair is located in Sovenia, a small European country, which borders Italy and Austria.
The Troll DW is now the worlds most popular BASE canopy. Fast on heading openings, crisp handling, good deep brake flight and a powerful flare make the Troll an excellent all round BASE canopy perfect for slider up and slider down jumps. The Troll was created using specialised computer software for designing and analysing low speed airfoils and wings. The 3D wing is transfered into 2D top and bottom panels and ribs. Using Advanced Technology AIR foil shaping methods, it is possible to obtain a parachute wing which has desired airfoil shape over the whole wing span not only at the ribs.
Although the aspect ratio generally has a much greater effect on parachute performance than airfoil design, the Troll's airfoil section is used to tailor the flight characteristics to suit the intended use.
The Troll is also available with the MDV valve system (Mono Directional Valve). The valves consist of a tubular shaped funnel attached to a mesh inlets on cells 2,3,4,5 & 6. This design allows the air to flow in to the cells during deployment and also during deep brake descent. The valves close during normal flight and do not have an effect on glide ratio. The MDV inlets allow the canopy to inflate and pressurise faster when jumping slider down, giving the jumper a controllable canopy quicker whilst also using less altitude. Troll is constructed using the highest grade materials available. Each parachute is hand made to meet finest quality standards. All materials are fully inspected and traceable.
The Trango is a state of the art, light weight, low pack volume canopy designed for Alpine BASE jumping and serious performance flying (tracking and wingsuit). The Trango utilises a revolutionary new fabric that reduces the weight and packing volume of the canopy by 25%! The smaller pack volume improves the aerodynamic shape of the container whilst the lower weight greatly reduces the fatigue from carrying the rig on long hikes.

The Trango is constructed from the highest quality materials. Each parachute is hand made to meet finest quality standards. All materials are fully inspected and traceable. The Trango is for slider up BASE jumps only. The lightweight fabric has a slightly shorter lifespan than regular F111, refer to the user manual for more details.
NOTE: From July 2008 the Trango will be manufactured with a grey light weight fabric and a ZP leading edge.
Atair is proud to introduce the OSP Slider Down BASE canopy, its design is *O*ptimized for *S*lider down *P*erformance. The canopy utilizes a revolutionary new leading edge slat technology to keep the air flow over the canopy attached even during very steep deep brake approaches. The OSP also incorporates a new thicker profile to further improve deep brake flying characteristics as well as a shorter line set to promote faster openings and better on-heading performance. The OSP design also has the advantage of reducing the forward speed of the canopy after opening which helps object avoidance in the case of an off heading opening. A steeper descent on the order of one to one is desirable as for slider down jumps the landing area is generally underneath or close to the object. Thus not only is a low forward speed beneficial, but a low descent rate also. The canopy profile of the OSP has been specially selected to enable steep landing approaches, generating high lift even when the flow is partially separated.
The maximum lift coefficient is further increased through the use of a SLOT formed by a leading - edge auxiliary airfoil called a SLAT. The first 10 % of the leading-edge is made of ZP fabric which covers the leading edge of the canopy and creates the slot. The air flows from inside of the canopy through the slot and over the airfoil. This results in a delay of airflow separation. Use of the SLAT allows the airfoil to be flown at a higher angle of attack before stall will occur and thus achieves a higher maximum lift coefficient . The SLATs are applied to the leading edge of cells #3, #4 and #5, because rectangular wings stall in the middle first. The OSP is intended for slider down and sub-terminal slider up jumps (ideally for 5 to 8sec delay slider up). Jumping the OSP for full terminal jumps is possible but not recommended as the openings may become uncomfortable.
