App Description

A-EFIS is an Electronic Flight Information System for airplanes, which runs right on your iPhone/iPad. A-EFIS works perfectly with the internal sensors of your iPhone/iPad

The only difference of this, free, version with the paid version is that this version is in black and white.

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 AIRPLANES. NOT TO BE USED IN HELICOPTERS OR LAND VEHICLES BECAUSE INDICATIONS WILL NOT BE CORRECT. USE ONLY IN AN AIRPLANE!

Features:
- Artificial Horizon (AHRS)
- Ground speed (via GPS)
- Altimeter (via GPS)
- Vertical speed (via GPS)
- Turn coordinator
- Slip ball
- Compass
- True course indicator (via GPS)
- Deviation from true track indication

A-EFIS has been extensively tested on ultralights, LSA, general aviation and even 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 leveled flight. You will practically have the same flight data as the pilots in the cockpit!

IMPORTANT NOTICE: A-EFIS is not a certified aviation instrument. Do not rely on A-EFIS as your only navigation aid. Failure to comply to this warning may result in property damage, serious injury or death. You assume total responsibility and risk associated with using this application.
