Tap the Settings icon (gear) in the top-right corner of the home screen. You’ll see threshold cards for each aircraft type: Glider, TMG, SEP, Trike, and Custom. Each card shows the current takeoff and landing detection speeds. Use the + and − buttons to adjust, or tap the value to type in a specific number. The default value is shown in brackets for reference. If you want to start over, tap the reset icon to restore the original values. These thresholds determine at what GPS speed the app recognizes a takeoff or landing, so adjust them to match your aircraft’s characteristics.
