## A-EFIS Black and White Description
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.

## A-EFIS Black and White Reviews in United States

### ***** "Legitimate!"
I am extremely impressed with this application!
Only using the free version for now but will be upgrading to the paid subscription the closer I get to finishing building my airplane. I am very thankful to have access to such a precisely formatted AHRS system as an augmentation to my primary flight instruments.
Highly recommended!
Many thanks to the developer!
-- Yellowhammer13, 2021-02-22

### ***** "Great App"
Simply the best out there simple and intuitive. Doesn’t try to do too much and does what it does very well.
-- DesertPilot.com, 2020-10-23

### ***** "Great!"
I have not flown with it yet, but if you think about it, a couple years ago it would cost big bucks to get this capability from Garmin or some of the other guys out there.
-- Auriga_5, 2020-05-02

### ***** "Love it!"
Has every thing I need to fly my Quicksilver MX. Groundspeed, altitude, rate of climb, G forces, compass etc. very good app
-- Chuck812, 2018-06-29

### ***** "Best bang for the buck"
This EFIS system is simply the best bang for the buck for entry level efis,sailplanes,sport planes, experimental and other aircraft. I have used this system for years. It is easy to use,dependable and most important, reliable and accuracy is top notch. I have seen this company develop new software every few months. They don't just initiate a new product;they are always adding new features which makes the flying experience even better.The developer offers this system for free but it's worth it to spend a few bucks and get the color version. Then when your used to the system buying the full efis version with airspeed and barometric altitude is well worth it. You won't find a better price. Spaceman
