  • continue to maintain a list of bugs, requests, fixes and workarounds. I personally have a D2 Air device so I should be able to confirm bugs and fixes as they appear.


    I've bolded anything that would generally consider to be a serious issue that impedes use of the watch or included functionality (ie. reboots versus display or other issues). Reply below with comments and I'll keep the list updated.

    Outstanding issues / bugs:

    • [WATCH] Measurement of PulseOx is inconsistent during flight (with FLY app)
    • [WATCH] GPS is incredibly slow to acquire an initial fix (up to 60 seconds) compared to other D2 devices
    • [GPS] TO BE CONFIRMED - cannot receive a GPS fix within the flight deck of an Airbus A-320 (and several other aircraft)
    • [CONNEXT] none


    Feature requests:

    • none at this time


    Fixed issues:

    • [APPS] The activity stops on FLY app after ~2 minutes at slow speeds when Flight Timer is set to 'Manual' [fixed in 2.60]
    • [WIDGETS] Waypoints widget doesn't handle single direction runways (eg. Rwy 23 at EDDW) [fixed in 2.60]


    Old issues [could not be confirmed or appear to work as expected]:

    • none at this time
