How can I help?

We recommend that Readers be powered off during a flight and not used for scanning a Sensor, if restricted by flight regulations. Aviation regulations dictate that a flight crew may decide that they do not want any electronic devices powered on during a flight regardless of device. In general, the FreeStyle Libre 2 Reader and FreeStyle Libre 2 Plus Sensor are not restricted by flight regulations and can be used since it meets the RTCA guidance of use of medical devices on planes.

The strip port on the Reader can be used to take blood glucose or ketone readings during flight. Turning on the Reader with the Home Button will activate the radio.  Users must turn on the Reader by inserting a test strip so as to not activate the radio.
