FishBike Posted October 6, 2014 Posted October 6, 2014 I'm not sure what I am missing, but for some reason I'm unable to get the Sabre's cockpit to pressurize properly. I verified I have the canopy closed, the "press/ram" switch in the "press" position (on the left console), and the pressure switch at 2.75 psi (though it's the same at 5 psi). What I see is that cockpit altitude = actual altitude, oxygen gets used up quicker than expected, and toggling the pressure switch between 2.75 and 5 psi doesn't seem to do anything. I must be missing a step somewhere.
