AHRS Utility vs iEFIS Pro

AHRS utility is a free application designed to configure Levil devices before flight and to display Levil's AHRS data graphically and numerically. This application is only compatible with the Attitude and Heading Reference System from Levil Technology, model AHRS G mini, iLevil series and BOM series. Users must be connected to the wireless network of the Levil AHRS. The application will NOT display airplane attitude based on the internal gyros of your iPad/iPhone or GPS data. AIR DATA: Air data is only available on the AW model or BOM. If you have an iLevil SW, Air data will be derived from the internal GPS on the iLevil. Engine: You must have a compatible engine information system connected to the iLevil to display this information. This application is not meant to be used as a Primary Flight Display or for IFR flight.

i-EFIS simulates a modern glass cockpit for general aviation and provides the following features: 1. Display iOS iPhone and iPad sensor data: The attitude indicator is driven by the 3D MEMS chip, speed and altitude come from the internal or external GPS (only iOS devices with cellular connection have the integrated GPS!) 2. Or connect the iPhone to a iLEVIL „SW“, „AW“ or „Sport“ device (available at the LEVIL company or in many pilot shops) by WIFI device to get precise attitude and GPS data. 3. A 80 or 360 degree course rose (change with tap on airplane symbol) 4. Magnetic and True GPS track (display in white with with track line) 5. Magnetic or True Heading, heading data is provided by internal compass and is not always reliable. 6. iEFIS Pro version (simple upgrade via inapp purchase!) displays a worldwide airport database and always shows the bearing to the nearest airport from your position with distance, elevation and runway orientation of the main runway of that airport. How to use i-EFIS 1. Tap the speed window to toggle speed units: km/h - mph - knots. Speed displayed is a GPS ground speed 2. Tap on the altitude window to switch from feet MSL to Meters MSL 3.
