Do canopy bottom skin vents (number, and configuration) give rise to differences in heading control for delays of PCA through 3 second? I was just looking at the Flik II, BJ and OSP. The canopies are 3-vent (cells 2,4,6), 4-vent (cells 2,3,5,6) and 5-vent (2,3,4,5,6) respectively. Is venting solely related to inflation speed or does it seem to affect heading for short delays? At the same wingloading, is it a false assumption to say the BJ (4-vent) would open and get flying faster than a Flik II (3-vent)?
