SQ
Reserve square parachutes with a manual deployment, designed for paragliding pilots
New product from Sky Country – SQ series of rescue parachutes of square shape. Square parachutes have a number of advantages over traditional round ones – they are more stable when descending and have a higher drag coefficient — sink rate is lower with the same surface area. SQ-33 is certified in accordance with EN-12491 standard. At a weight of 120 kg sink rate is 5 meters per second. We allow the use of SQ-33 for a weight of up to 140 kg. Vertical speed will not exceed 5.5 meters per second. In 2019 we certified the lightweight parachute SQ-23LT – it weighs 1 kilogram, maximum weight in flight is 95 kg.
To reduce weight, the thin lines Liros RL Safety Line Dyneema 1.3 are used – as the number and length of the lines is higher compared to the traditional parachute.
Packing of a square parachute is almost identical to that of a round parachute – the instruction is in the users manual. We recommend re-packing of the parachute once every 6 months.
