Standard-7 cell
Let’s talk about one of the most important parts of your equipment. Try skydiving without it and, let’s just say, it’ll be a challenging situation!
So, the reserve. Is there anyone who doubts the importance of this part of the skydiving equipment? It’s not a coincidence at all that the reserve canopy is located neatly packed in the upper portion of the skydiver`s gear, has an optimal design, and meets the requirements all pilots need!
A special place among the variety of Skylark’s parachute designs takes the STANDARD-7. It’s a 7-cell rectangular ram-air pressurized gliding canopy. It has an optimal aspect ratio (span to chord ratio) and a modified wing profile shape. Due to these design features, STANDARD-7 achieves a good glide & flare performance intended for providing a stable descent and a soft landing in case of a main parachute malfunction.
The STANDARD-7 has a thoroughly thought-out design and proven reliability. The canopy has been tested according to TSO-C23d requirements with a performance margin under various conditions. For all possible scenarios, in which a skydiver would use the reserve, numerous tests have been performed. For either manual or automatic activation, either immediately or after any delay, at altitudes up to 4500 m above sea level and after separation from the aircraft at indicated airspeed from 0 to 292 km/h. [Tests were also conducted for mass and speed values exceeding the specified values by 20%]. The max force you experience momentarily upon the reserve opening is 8.6 G.
Make your canopy selection based on canopy performance characteristics according to parachutist skills and activity.

The entire canopy of the STANDARD-7 is made of low-porosity F-111 nylon fabric (PIA-C 44378. Type IV) and reinforced with standardized tapes (MIL- standards) that are widely used in the parachute industry. Optionally, the parachute can be made of PN-9 fabric if a smaller pack volume is required (saving approximately 11-13%).
Main suspension lines are made of Spectra / Microline 725 lb, lower steering lines are made of Spectra / Microline 1050 lb. A slider has a hole in it to make the parachute opening more stable and to decrease the opening shock. Maintenance requirements for the reserve parachute STANDARD-7
You don’t have to perform any specific operations when taking care of your parachute, but it is mandatory to complete the required maintenance of a reserve canopy in order for skydiving gear to retain the characteristics and the declared service life. When not in use, you must stow away your reserve parachute in a parachute pack in a dry, cool, clean and UV ray’s free environment. An ambient temperature must be from -30℃ to +30℃ and a relative humidity not greater than 80%.
STANDARD-7 was designed to last a maximum of ten times if properly maintained as per the manufacturer’s recommendations. Designated use period – according to the technical condition within the designated service life. Storage time up to 20 years.
Fly safe!
