New product from Sky Country – a rescue parachute SQ-33 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 in progress of certification in accordance with EN-12491 standard. At a weight of 120 kg sink rate is 5 meters per second. We allow the use of a parachute for a weight of up to 140 kg. Vertical speed will not exceed 5.5 meters per second.
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 SQ-33 users manual. We recommend re-packing of the parachute once every 6 months.
A square parachute with an area of 26 sq.m. with a flight weight of up to 110 kg, as well as light versions of both parachutes are in progress of development.

* – SQ-33 is certified with a load of 120 kg, but we consider it possible to use it with a load of up to 140 kg. At the same time, the descent rate will be 5.5 m/s.
