Leia vs Safire 4

JYRO Leia · JYRO Safire 4 · Canopy explorer

Manufacturer facts side by side, with the source on every row. Nothing on this page says which canopy to choose or what wing loading to fly — that is a conversation for you, your canopy coach and your drop zone.

What differs — read from the data

  • Leia and Safire 4 are both made by JYRO.
  • Planform: Leia is listed as elliptical; Safire 4 as semi-elliptical.
  • Leia has 7 cells; Safire 4 has 9 cells.
  • Leia is cross-braced; Safire 4 is not.
  • Leia is listed in 59–99 sq ft; Safire 4 in 109–189 sq ft.
  • The listed size ranges do not overlap.
  • JYRO's recommended wing-loading range: Leia 2.2–2.8 lb/sq ft, Safire 4 1.0–1.6 lb/sq ft. A range is a manufacturer envelope, not a target.

Structural facts only (manufacturer, planform, cells, bracing, sizes, chart system). How each wing flies is described below in the manufacturer's own words; how it flies for you is a question for a canopy coach.

Flight wording is quoted or closely paraphrased from each manufacturer's own documents; where a manufacturer publishes nothing for a row it says "not published". No airspeed figures are published by either manufacturer.

Your wing loading on each size

Enter an exit weight to see exit weight ÷ size for every listed size of both canopies and where each number sits on the manufacturer's own chart.

Wing loading = exit weight (lb) ÷ size (ft²). PD's chart lists the MAXIMUM exit weight per skill category — the category shown is the lowest one whose maximum covers your weight, by PD's own rule. JYRO's range is a manufacturer envelope, not a target. The two systems are never translated into each other.
