Part of the problem with bulging of the forward part of the
Legacy canopy may also be due to the inflatable canopy seal. As supplied
by KCI, the pressure switch is usually set at 15 -20 psi. Lowering that
pressure to 10 - 12 psi significantly reduces the stress on the canopy, and
still provides adequate sealing in flight. To change the setting, there's
an adjustment screw on the switch, but you have to set up some sort of manometer
system to check the on/off pressure setting as you're adjusting the
screw.
