Getting the app

How do I get VNAV?

Open the VNAV page on the App Store on your iPhone or iPad and tap Get. VNAV is free to download.

I can't find VNAV on my iPhone or iPad

VNAV runs on iPhone and iPad with iOS or iPadOS 17.6 or later. Search for “VNAV” in the App Store, or open the link above on your device. If it doesn't appear, open Settings → General → Software Update and check that you are on 17.6 or later.

Feedback

How do I send feedback?

Use the feedback form on this site, tap Send feedback in the app, or email us. Tell us how your descents actually went. That's the most useful thing you can send.

We send a thank-you email to the address you give when your feedback arrives. If you don't see it, check your junk folder.

Devices and GPS

Which iPhone or iPad do I need?

Any iPhone running iOS 17.6 or later, or any iPad running iPadOS 17.6 or later. To check, open Settings → General → About and look at the software version.

For live GPS, every iPhone has GPS built in. On iPad, a cellular (Wi-Fi + Cellular) model has GPS built in, even without a data plan. Wi-Fi-only iPads have no GPS, so they need an external GPS receiver connected over Bluetooth. Without GPS you can still plan by typing in distances.

Does VNAV need internet in flight?

No. VNAV works fully offline from your device's GPS. Load your routes before you fly. Nothing in the app needs Wi-Fi or cell data in the air.

Why doesn't my altitude match the altimeter?

Your device gives GPS altitude, which is not pressure altitude. The difference changes with temperature and pressure. VNAV lets you enter an altitude offset (the difference between your altimeter and the GPS reading) so the path lines up with what you're flying. Always fly your altimeter.

Using VNAV

My airplane has a G1000. Do I need VNAV?

Probably not. VNAV is built for airplanes without vertical navigation in the panel. If your avionics already provide VNAV, they should stay your primary source.

Will the top of descent alert work if I switch apps?

Yes. With Alert in background turned on in VNAV’s Settings, you get a chime and notification at top of descent even when your screen is locked or another app, like ForeFlight, is in front. It also comes through Do Not Disturb and most Focus modes.

Allow notifications and location when VNAV asks. You’ll see the blue location indicator while an alert is armed. It goes away after the alert. The alert won’t fire if you force-quit VNAV by swiping it away in the app switcher.

Where does the navigation data come from?

VNAV includes FAA fix data for the United States, built from the FAA's 28-day cycle. The app shows which cycle you have and warns you when it expires. Install the latest VNAV build to get current data. Data outside the US isn't included yet.

How do I report a wrong result?

Tap Report a wrong result in the app. It prepares an email with the planner values on screen, and you can read and edit it before sending. If you email us directly, include:

  • Your aircraft and the descent profile you used
  • The fix, altitudes, ground speed and angle or fpm you entered
  • What VNAV showed and what you expected
  • A screenshot, if you have one

Your data

What does VNAV collect?

The app collects nothing. Your location and saved data stay on your device. Feedback you send through this website is used only to read and reply to it. See the privacy policy for details.

How do I delete my feedback or beta request?

Email [email protected] from the address you used and ask us to delete it.

Planning aid only. VNAV is not certified and is not a navigation or flight-control device. Check every result against your avionics, charts and approved procedures.
