Päävarjo

Päävarjo is a Finnish term that translates to "main parachute" or "reserve parachute" depending on the context, but most commonly refers to the main parachute in the context of parachuting. It is the primary canopy deployed to slow a skydiver's descent. Unlike a reserve parachute, which is designed for emergency use and is packed by a certified rigger, the main parachute is packed by the skydiver or a designated packer and is intended for routine deployment.

The design of a päävarjo has evolved significantly over the years. Early parachutes were often square or rectangular, but modern main parachutes are typically elliptical or rectangular with a distinctive wing-like shape. These ram-air canopies allow for steering and control, enabling skydivers to navigate towards a designated landing area. They are constructed from lightweight, durable fabrics like ripstop nylon and are designed to inflate rapidly and predictably when deployed.

The deployment of a päävarjo is a critical phase of a skydive. Skydivers are trained to execute specific procedures for deploying their main canopy at a predetermined altitude. This involves pulling a pilot chute, which in turn extracts the main parachute from its container. Once deployed, the parachute opens and inflates, creating drag that significantly reduces the descent rate, allowing for a safe landing. Regular maintenance and inspection of the päävarjo are essential to ensure its reliable performance.
