Hello, I had a problem with my IXEG 737 in the coroute section in the fmc. But today, I have encountered another problem but this time is from the cabin altitude alert. Whenever I spawn at a high elevation airport, the takeoff alert starts beeping and I can only mute it with the ALT horn cutout. If somebody can help me set the cabin altitude thing I would be thankful since im new in the 737.
