Radar Aéreo is an Android application that allows users to track aircraft in real-time on a map in some regions of Brazil while listening to pilots' communication on the radio. By clicking on an aircraft, users can view data such as flight, registration, aircraft model, and, when available, origin and destination of the flight. The app also provides daily news about aviation in Brazil, including logs and alerts on the movement of aircraft and interesting situations at airports across the country.

One of the best features of Radar Aéreo is the ability to view moving aircraft in real-time and listen to the radio communication of the pilots. Users can also access news about aviation and forum logs with information on interesting aircraft, flight situations, and airports. However, it is important to note that the app can only track aircraft equipped with an ADS-B transponder, and the radio coverage is limited to a part of the southeastern region due to antenna range limitations.

Overall, Radar Aéreo is a great app for aviation enthusiasts and those interested in tracking aircraft in Brazil. The app is free to use, and users can visit the developer's website for more information and to provide feedback or report bugs.
