Not sure what this means and can't find the answer in the documentation. Almost every time I'm descending for a landing, I get the amber "Off Shed Descent" light on the cabin pressurization panel. I have the manual valve closed, the system set to auto and the landing altitude of my destination set.Anyone know what I'm doing wrong?Thanks in advance.

I think that means your cruise altitude setting for pressurization doesn't match the altitude you reached. So when you start the descent the controller is "off schedule." It is just an alert I believe.

It goes off if you don't reach the cruise altitude selected in FLT ALT window, but it also sets the pressurization landing altitude automatically to takeoff elevation. If you change the FLT ALT, then that "automatic abort capability" is lost.

Hi The OFF SCHED DECENT light on the cabin pressure controller on the overhead panel tells you that the system will control the cabin pressure for a return to the take-off field. The off shedule decent begins when the airplane starts to decent off schedule (before it gets to cruise altitude set in the FLT ALT window on the same contol panel).The OFF SCHED DECENT system only functions when cabin pressure system is in AUTO or ALTN mode not in the MANUAL mode. If you divert to a other field than the take-off field or continue's the flight other the scheduled flight level reset the FLT ALT to the current altitude and set LND ALT to the landing field elevation.Greetings Mark.
