The canopy has a non-inflatable weather seal and an inflatable pressure seal. The
pressure seal is pneumatically inflated using cooled engine bleed air tapped off the
anti-G system. The one piece, seamless pressure seal is automatically inflated as
soon as bleed air inflow is available (e.g., engine on and bleed air inflow switch
NORM or HI) and weight is off the right main landing gear.
CANOPY OPERATING PROCEDURES
To close the canopy from the inside:
WARNING
Make sure only one occupant is operating the canopy handle, to avoid
