As all DJI drone users know, the DJI Go and DJI Go 4 apps provide a wealth of useful information about your past flights that can be accessed via the “Flight Recorder” option in your app.

You can review data on every individual flight and see how far and high you went on each flight. You can even see how much battery power was used and if you had any warnings in flight.

The app breaks down your data into some interesting chunks. But, argues the author, there’s even *more* you might want to know…

While this is a useful tool it has only two export options: One is a CSV file you can import into a spreadsheet app and the other is a single image that contains a map of the flight, with the distance and length of the flight time in text below the map.

Currently the DJI Go App can’t show you if one of your batteries is possibly getting hot in flight or if one battery is not lasting quite as long as another. It also can’t show you what the weather or wind conditions are during a flight.

A free online service called Air Data (previously called Healthy Drones) can do that and more.  The service allows you to upload your log files from your DJI drone and will provide you with even more granular detail.

The Air Data service currently supports logs from DJI Go / DJI Go 4 / Litchi / DroneDeploy / AutoPilot / Maps Made Easy / Ultimate Flight / Top Pilot. The exact way you export logs from each application into Air Map is slightly different, but none of them is difficult.

Regardless of app, the first step is to create a free account with Air Data. Then, if you’re using DJI Go or DJI Go 4 you can copy files off your mobile device and upload them to the server – or you can provide Air Data with your DJI Go account information and it will download the logs directly from your DJI account automatically. 

USE COMMON SENSE

Be aware sharing your account credentials with any third party is rarely the best option. For example, your DJI account may have access to stored credit card or other personal information if you use the same account to access the online DJI store. Air Data has a number of additional ways to sync your DJI flight logs through apps and other methods that do not require sharing any DJI account information.

In fact, Air Data dropped TDC a note explaining that “users can also use our app, HD Sync (https://app.airdata.com/sync-app). HD Sync on Android does not require any of the DJI credentials, and is very simple and easy to use. HD Sync on iOS does ask for the DJI credentials, as it can’t access the local flights on the iOS device.

“DJI user credentials are only used to download flights from the DJI servers, and are not sent to Airdata. As such, the HD Sync app is a good alternative for folks who would prefer to not share their login with us.”

Once your logs have been uploaded to Air Data, you can see a high-level overview of all your flights – or dive into detailed information on any specific flight.  You can also share your flight data with others and allow them to see as much (or as little) data about each flight as you wish to share.

Air Data has four levels of accounts. The free option is limited to your last 100 flights and will only store your flight data for six months. The additional tiers of service provide the ability to store more flights for longer periods of time, as well as provide additional functionality.

“FREE” IS A PRETTY GOOD DEAL
That said, the free service provides you with most of the important data and can show you sensors and control health, battery efficiency, minor and major battery voltage deviations, battery amperage reports and may other aspects of your flight. You can also download KML files that you can import into Google Maps or Dashware (a program that can be used for data overlays on flight videos).

Air Data can give you an insight into a potential battery or other drone issue that may be too minor for you to notice any other way. It can also show you communication errors that may indicate some of the locations you are flying in may have radio interference that you are not aware of.

Additionally, if you pay for the first tier of service for $3.00 US a month ($2.75 monthly on an annual plan) you remove the ads from the site and get wind direction and speeds that have been calculated based on the position, thrust and groundspeed of the aircraft. This allowed me to see that the Mavic Pro was able to hold its position nicely near a lighthouse in a wind stronger than 42 km/h (26 mph) – as you can see in the grab below.

Detailed reports like this show windspeeds at different points of the flight

Here’s a video taken from that flight!

For me this has been a valuable tool to help ensure my drone is healthy and working well every time I use it.  It’s also another great way to share data from successful flights with other drone enthusiasts.
