This is a tiny suggestion for the next update. Shouldn’t have to be a major update, maybe just some QOL changes.

Maybe a system of alarms and sound making parts could be added for cars and detailed cockpits. A customizable horn could be used on car builds, while a designated “alarm” part could be used inside cockpits. You could change what it alerted you to, from stall warnings, TCAS warnings, Altitude readouts for landing (can’t think of the term for that)*, low fuel alerts, fire warnings, damaged landing gear or engine warnings, etc.

Edit: *GPWS CALLOUTS, THAT’S IT.
