A-EFIS black white is an Electronic Flight Information System (EFIS) designed for airplanes and available on Android platforms. This free version of A-EFIS offers a fully functional experience, with the exception that the main EFIS display is in black and white.

A-EFIS utilizes digital filtering methods and state-of-the-art stochastic models to provide exceptional accuracy and robustness. It includes features such as an Artificial Horizon (AHRS), ground speed, altimeter, vertical speed, turn coordinator, slip ball, compass, true course indicator, and deviation from true track indication.

It is important to note that A-EFIS is only compatible with fixed-wing aircraft and should not be used in helicopters or ground vehicles. The application has been extensively tested on ultralights, LSA, general aviation, and even airliners. However, it is not a certified aviation instrument, and users should not rely on it as their sole navigation aid.
