A-EFIS black & white

A-EFIS Black & White is a comprehensive Electronic Flight Information System designed specifically for fixed-wing aircraft, running directly on your smartphone or tablet. Utilizing your device's internal sensors and GPS, it provides critical flight data such as an artificial horizon, ground speed, altimeter, vertical speed, turn coordinator, slip ball, compass, true course, and deviation from the true track. This free version offers all functions with the main EFIS display in black and white.

Employing advanced digital filtering and stochastic modeling techniques, A-EFIS ensures accuracy and robustness suitable for ultralights, LSA, general aviation, and even airliners when positioned near a window for GPS reception. Note that A-EFIS is not certified for aviation use and is intended only as a backup instrument; it should never be used in helicopters or ground vehicles.
