The AF-2500 is a complete aircraft monitoring and data acquisition system designed for aircraft with 4 or 6 cylinder engines. The system continuously monitors and displays all aircraft engine data on a sunlight readable color LCD display, and checks current engine readings against user-adjustable set points. Unlike other systems, the display can be customized to the user's preference. Any of the standard instruments can be eliminated or added to the screen.
