  1. if we have a canopy exceeding a air permeability of 30 cfm it is ok if it is a round canopy even from the 40s

    if it is a strato star well let´s look at the wingload :/

    if it is a small competition velo it is not a perfect decition

    the manual of a given ram air reserve manufacturer states the reserve is build of 0-3 cfm fabric material.
    if the fabric has more than that (e.g. assymetric 10 cfm or left to right more than 25% difference or simply 30+ cfm ) it is ...?

    are there anny borderline readings in the cfm topic available?
