XPlaneMonitor is a free app that gives you a quick and easy way to find out important information about your aircraft. It displays the latest data about the plane's brakes, flaps, landing gear, reverse thrust, G-forces, time, and distance to NAV1, without having to look around the cockpit.

It is useful for both pilots and passengers, and works with many aircraft from different manufacturers. It is free to use.

If you are a pilot, it is useful to know the status of the aircraft. If you are a passenger, you can use it to know the status of the plane and the conditions in the air.
