Added IAS to CloudAhoy’s Glass Gauges

The airspeed tape of our glass cockpit now include IAS and GS, in addition to TAS.

Less than an hour after we published our previous blog post about the glass cockpit gauges, we started receiving emails requesting a display of the Indicated Airspeed (IAS) in addition to the True Airspeed (TAS). It’s available now. In the example below, IAS is 117 knots, ground speed (GS) is 104 knots and TAS is 120 knots.

If your flight is imported from Garmin G1000 or Garmin G3X, the IAS number is the actual indicated airspeed that was displayed in flight. If you are logging the flight in a different way, we display a computed IAS.



Note: the glass cockpit screenshot above was taken on a Macintosh. See this for its look on Windows and iPad.

Glass gauges – now in beta

We started beta testing of our glass-cockpit-style gauges, and would like to invite you to try them.

To add the gauges to your debrief, select Glass Cockpit from the Viewing Options menu.


  • You do not need AHRS information to display the glass gauges. CloudAhoy displays calculated attitude, rather than the measured attitude.
  • You don’t need to wait for your next flight; the glass gauges beta can be used when debriefing any of you past flights.

The gauges appear differently on different systems:
–  In 2D mode, and in 3D on the Mac, the gauges are displayed over the main window (A and C, below).
– In 3D on Windows, the gauges are shown in a resizable/movable window (B).

3D: Mac 3D: Windows 2D: iPad, Windows, Mac

Our current implementation includes an airspeed tape, attitude indicator, altitude tape, vertical speed tape, and a heading indicator.

As always, your feedback is very welcomed.  Please let us know ( how the gauges work for you.

Help is on its way…

A new addition to CloudAhoy – a comprehensive Help.  Click this to check it out.

We have collected our existing how-to articles, added many more, created some videos – and made it all accessible by clicking the Help button (see below).

help_homePageYou will find  tips for an effective VFR and IFR flight debriefing, tips for using your GPS, information about importing flights from ForeFlight or from Garmin G1000, and much more.​

This is a work in progress. We plan to continue to add more information and tutorials. One of the insights we brought back with us from Oshkosh in August was the realization that many of our users were not aware of important existing capabilities. This central repository for tutorials and help is a direct result of that realization.

ForeFlight’s route on CloudAhoy



When you import a flight track from ForeFlight , we now also import and display ForeFlight’s route. This provides you with a valuable tool to debrief “planned vs. actual”. You don’t need to do anything special to get this route – it’s part of our import process.

The example above shows CloudAhoy displaying ForeFlight’s route in magenta. The actual VFR flight followed the planned route from KISQ till KNMN, then deviated from the route to go around weather, and finally joined the route from RIPON to KOSH.

The following Q+A will explain it in more details.

Q: Remind me – how do I import flight tracks recorded by ForeFlight?
A: See this.

Q: I entered a flight plan into ForeFlight before takeoff, then modified it in flight. Which will be displayed in CloudAhoy?
A: The last one. CloudAhoy imports the flight path as defined immediately before landing, i.e., the path including all the changes made in flight.

Q: How is this feature related to CloudAhoy’s Intended Flight tool?
A: When we import the route from ForeFlight, we automatically create an Intended Flight segment, colored in magenta. After the flight’s import, you can of course modify the route, change the color, or delete it altogether. And you can use the magentaEye symbol to hide or show it.

Q: I see labels with coordinates. What do they mean?FF_intendedPathS2
A: Your ForeFlight path probably did not start or end at a known fix. See the example on the right; the pilot flew for some time (the southeast section of the flight) before setting ForeFlight direct-to KRUT. As a result, the displayed magenta route starts at a coordinate where the direct-to was set.


As usual, please email questions or feedback to us at

Importing flights from Garmin G3X

If your aircraft is equipped with Garmin G3X avionics, you can now debrief your flights using rich high-quality flight data captured by the G3X. It’s very similar to debriefing Garmin G1000 flights, which we described earlier.

The G3X writes flight data into an SD card. To debrief the flight you need to import that data into CloudAhoy. This blog described how to do it.G3X SD Card

Logging the flight
Important: please consult your G3X manual and/or the aircraft’s owner for details specific to your aircraft.

  1. Before turning on the avionics, insert an SD card into the SD Card slot. If you have both a PFD and an MFD, the card should typically be inserted in the master, i.e., the PFD.
  2. During flight, the G3X automatically writes the flight data into your SD card.
  3. After the flight, remove your SD card. You now have the flight data in the SD card.

Importing to CloudAhoy

  1. Insert the SD card in a card reader connected to your desktop or laptop computer. The SD card’s folder will appear on the desktop.
  2. G3X DataLogOpen the folder. It would typically contain a data_log folder, and in it the flight’s data file in CSV format.
  3. Open a web browser and login to your CloudAhoy account.
  4. G1000-SDCard-5Click the Flight Import button. Enter the flight’s pilot names, tail number and optional remarks (you can edit all these later), select the CSV file with the data, then click Import.
  5. The flight now appears in your flight list, and is ready to be debriefed.

Debriefing G3X Flights

CloudAhoy can display the rich G3X data in graphical as well as numeric forms. The screenshot below has profiles showing a specific maneuver as the aircraft is pulling 2.4G while making a 62° left turn.

CloudAhoy can display about 40 different flight profiles for flights imported from G3X, such as OAT, IAS, EGT and even transponder codes used during the flight. For more information about advanced flight profiles, see G1000 and G3X flight data with CloudAhoy profiles.
