Calibrating Sensors
Before you get started with the XC Vario or any other of theFlightVario vario apps it is highly recommended to calibrate the sensors of your phone!
Calibrating the sensors of your smartphone
Open the menu by either touching the menu icon on the lower left (touch the screen once to have it appear) or swipe from left to right. Choose Calibration and perform the following steps:
Move and rotate the phone around all axes to improve sensor awareness. This is optional but recommended especially if your phone has not been used for a longer time.
Put the phone on a flat surface like a table so sensor readings will not be affected by unintended motions.
Push CALIBRATE and wait till the calibration is finished
Activate AI Sense (for newer phones with barometer and inertial measurement unit like Pixel7 and Pro, Pixel 6 and Pro, Pixel 5, Pixel 4a, Samsung Galaxy S22, S21 5G, A71, S10e, S9+, S8, S8+, S7 Edge M32 5G, Sony Xperia XZ2 Compact, LGE LG G6, OnePlus 9 5G, Huawei Mate 20 Pro - based on user feedback)
Note: Do not move the phone around and do not open/close any doors or windows as this will affect sensor readings.
Calibrating the sensors of your phone is the most important things to enable your phone as a vario for paragliding. Since no phone and combination of sensors is exactly identical to another, it is crucial to measure sensor characteristics first. Calibration looks at the accelerometer, gyroscope, magnetometer and barometer also referred to as pressure sensor. Depending on the precision, latency and drift characteristics of these built in sensors, the instant vario feature might be used.
