A-EFIS black & white APK

A-EFIS is an Electronic Flight Information System for airplanes, which runs right on your smartphone/tablet. A-EFIS works perfectly with the internal sensors of your device and it is an ideal EFIS to always have as a backup.

This is the free version of A-EFIS. The free version is fully functional with the exception that the main EFIS display is in black and white only.

A-EFIS makes use of digital filtering methods and state-of-the-art stochastic models in order to achieve exceptional accuracy and robustness.

ATTENTION: A-EFIS ONLY WORKS ON FIXED-WING AIRCRAFTS. NOT TO BE USED IN HELICOPTERS OR GROUND VEHICLES OF ANY KIND. USE ONLY IN AN AIRPLANE, OTHERWISE INDICATIONS WILL NOT BE CORRECT!

A-EFIS has been extensively tested on ultralights, LSA, general aviation and airliners. Hint: To use A-EFIS in an airliner, just sit close to a window (in order for the device to be able to receive the GPS signal), put the device in a stable position and press "AHRS calibration" when the aircraft is in levelled flight. You will practically have the same flight data as the pilots in the cockpit!
