It is a flight debriefing service for pilots. CloudAhoy’s free iOS or Android app collects
flight data during the flight. After the flight a pilot can debrief the flight from the web or from the iPad
Instead of using our apps for flight logging, you can also import flights logged by other devices or apps.
CloudAhoy integrates weather information, airport and navigation information, aircraft information and a knowledge about flight operations. It has specialized analysis modules for fixed-wing planes, rotorcraft and gliders. More...
CloudAhoy Standard is free for 35 days after the first flight.
Afterwards CloudAhoy Standard is $45/year, or use CloudAhoy Free for cloud-based flight tracks. More...
The abbreviated answer is that your information (including email)
and flight data will never be
disclosed to anyone outside of CloudAhoy (and its contractors who are bound by written obligations of
confidentiality), unless you agreed to it, or CloudAhoy is required to disclose information by law. For the
Yes. Download from Apple's app store, or from Google Play You can log your flights using either the iOS or the Android CloudAhoy app.
CloudAhoy is available in every country on the globe, with very few exceptions. We have customers in every continent except Antarctica.
CloudAhoy's accounts are individual accounts, and must be created individually for the instructors and for the students.
The recommended way of using CloudAhoy in a school environment is to use CloudAhoy Groups, each with its own policy. Example: a CFI may define a group and invite all his or her students to the group. The CFI will set up a policy whereby only he can see the flights shared with the group, and the students cannot see each other’s flights.
Note that in a dual flight both the student and the CFI can have the flight automatically listed in their flight list.
Yes. CloudAhoy logs X-Plane flights over WiFi, no additional hardware or software needed. It can also log Microsoft Flight Simulator's flights. You can also log your simulated flight on other apps, such as ForeFlight, and import the data to CloudAhoy.
No. CloudAhoy is designed for debriefing flights, and flights only. When using it you must be actually taking off, climb, cruise and then descend and land.
Download the CloudAhoy app from Apple's app store or from Google Play, and
sign up. Or you can sign up from the web by clicking the "Sign Up" menu above.
After submitting the sign-up form, you will receive
an email with an activation link. Check your email, click the link, and your account will be
Next, run the CloudAhoy app and login to your account using the email and password that you have used for sign-up.
You are now ready to log your first flight.
Instead of using our apps, you can also import flights logged by other devices or apps.
Start the CloudAhoy app, enter your aircraft’s tail number and the name of the
pilots. Use the "swap" button to swap between the pilot and co-pilot names.
Before starting the engine, tap START in the CloudAhoy app. Make sure the GPS signal strength indicator in the app turns green.
If you are using your iPhone, iPad or Android’s internal GPS, make sure the device has good sky visibility. If you use an external GPS, place it for maximum sky visibility.
We highly recommend adding a “Start CloudAhoy” item in your checklist. We have added a "Start CloudAhoy" item to our checklists, just before engine start. In this way, the sum of ground and air times reported by CloudAhoy is approximately the Hobbs time. So just before starting the engine, start the CloudAhoy app on your iPhone or iPad, verify that the flight information is correct, tap START and if needed, secure the device in place. Then forget about CloudAhoy until after you land.
You can debrief the flight directly from the Debrief tab in your iPhone or iPad CloudAhoy
app (not available in the Android apps),
or by signing in to your account from any computer including Windows, Mac and Android. You will see the flight in your flight list. Click The
Debrief icon to debrief your flight.
Don't worry about it -- our apps' data logging stops automatically after you land,
taxi to the ramp and park. You can always stop the logging manually by tapping the STOP button.
No. After take-off the app stops all communications with the CloudAhoy server. After landing the app waits until the iOS device has cellular or WiFi connection, and then uploads the flight data to a CloudAhoy server.
Yes. Read this.
It's very important for getting good data for your debrief.
Every iPhone has an internal GPS. Only cellular-capable iPads have an internal
GPS. Most (but not all) Android phones have an internal GPS.
The iPhone’s internal GPS is disabled in Airplane Mode, so make sure you disable this mode. Both the iPhone and the iPad’s internal GPS have a reasonable lateral accuracy, and so-so altitude accuracy. Luckily, CloudAhoy's digital filters significantly enhance the internal GPS's accuracy, so when you debrief your flight the lateral and altitude values are pretty accurate.
→ The device should see as much of the sky as possible, including when the aircraft banks.
→ Do not fry the GPS with direct sun radiation. Protect it and keep it as cool as possible.
→ Like any object in the cockpit, the iOS device should be secured for safety.
Yes. You would need to use an external GPS. See below.
Two possible reasons. One: you are using the iPhone/iPad's internal GPS, and
you have Airplane Mode. If so, turn Airplane Mode off. Two: you declined to let CloudAhoy access the GPS
data. To check if this is so and to fix the problem, open your iPhone/iPad's Settings, Tap Location Services,
and verify that Location Services is On, and that CloudAhoy is also On.
Unless you use an external Bluetooth GPS device (in which case you can put the
iPhone/iPad anywhere in the cockpit), the iPhone should be located such that it can "see" as much of the sky as
possible. For example, you can secure it on the glare shield, farthest from you. In sunny days, we recommend
covering it with paper, (e.g., an aviation chart, or inside an envelope) so it is not exposed to direct sun's
radiation and is thermally shielded from the hot dashboard.
An external bluetooth GPS provides a superior accuracy compared to the internal
GPS. Also, an external GPS is easier to place for optimum sky visibility. This is especially true for iPads
which are typically placed far from the window, e.g., on the pilot’s laps.
In principle, CloudAhoy can work with any bluetooth GPS device.
If you have used an external GPS which did not work well with CloudAhoy, please let us know.
CloudAhoy was tested and works well with the following external GPSs:
GNS 5870 MFI, GNS 1000 MFI
Dual 150, 160, 170
Bad Elf GPS Pro
Note: because the Bad Elf GPS is physically connected to the device, we only recommend it for cases where the device + GPS can be placed with good sky visibility.
Yes, but not directly. CloudAhoy cannot access the Status GPS, but you can log the flight with ForeFlight and then export the flight track to CloudAhoy.
Yes. For example, you can run an EFB app like ForeFlight Mobile HD, Garmin Pilot or WingX Pro, and run it simultaneously with CloudAhoy. To do so,tap START on CloudAhoy, then switch to your other GPS-based app. CloudAhoy will keep running in the background and will log the flight.
There can be several reasons why a flight is missing from the flight list, or is only partially
recorded. Read this.
