It’s important before each flight to properly configure the iPad’s wireless radios, especially when using a Bluetooth or WiFi accessory. This will help to both maximize battery life and reduce the potential for interference with the panel-mounted avionics. Here are our recommended wireless settings for various iPad and accessory combinations:
iPad with plug-in Bad Elf GPS
iPad with Garmin GLO, Dual XGPS or Bad Elf Bluetooth GPS
iPad with Stratus ADS-B/GPS Receiver
Cellular iPad with Internal GPS Receiver
IMPORTANT: After the iOS 11 update last year, turning off Wi-Fi or Bluetooth using the control center shortcut doesn’t actually disable those radios when you turn off the switch. Rather they only disconnect a Bluetooth or WiFi device, while keeping the radios active. Because of this, we recommend configuring these settings from the main iPad Settings app, and not the control center shortcut before flight.
