Support / FAQs

We hope you can find all the answers to your questions in our comprehensive FAQs. We have also created helpful videos that can answer many questions about using our apps.

    Do I need 3G or 4G (cellular) to use ForeFlight?

    Good question! The short answer is "no".

    Download all the charts and data you will need for your flight over a Wi-Fi Internet connection prior to takeoff.

    If you have a Wi-Fi only iPad, then you will be able to access charts, data, and your planned route while in the air, however you will not have any moving map display with ownship position. You need a GPS source for this.

    There are two options for your GPS source: a built-in iPad GPS or an external accessory.

    When choosing which iPad to buy, note that you have a choice to buy a Wi-Fi only or a Wi-Fi + Cellular model. Two big reasons to choose the Wi-Fi + Cellular option over the Wi-Fi only version are:

    1) The Wi-Fi + Cellular models include an internal GPS receiver that can be used to power ForeFlight's moving map display. And,

    2) You can use the Cellular Data feature to access the Internet where there is no Wi-Fi available. Check with your cell phone service provider for available data plans.

    In addition, a couple of things to keep in mind when using a Wi-Fi + Cellular iPad: You do not have to activate/use your Cellular data plan to simply use the built-in iPad GPS receiver. And we recommend that you put your device in Airplane Mode during flight. Airplane Mode turns off the cellular radio (so that you do not potentially use up your data plan while inflight), but leaves the GPS receiver on.

    If you choose a Wi-Fi only iPad, then you have several options available to connect to an external GPS receiver. Check out our Buying Guide for more information.


    Are external GPS receivers supported?

    You can use any external Bluetooth GPS receiver that is certified by Apple as MFi (Made For iPad, iPhone, or iPod). The Stratus ADS-B external receivers also provide GPS information to ForeFlight using a Wi-Fi connection. Please review our buying guide for the latest recommended gear.


    Should I use an external GPS with my iPad or iPhone?

    The answer depends on the aircraft you fly.

    If you fly a typical GA aircraft at less than 200 knots and below 12,000', then we recommend the 32GB iPad Air 2 or iPad mini 4 with Wi-Fi + Cellular. The Wi-Fi + Cellular model adds two things: cellular Internet access and an internal GPS chip. The internal GPS chip is fully adequate to provide moving map position information for the aircraft described above.

    Please note that you do not need to activate/pay for a data plan to simply use the internal GPS feature.

    If you fly a pressurized fast-mover at the flight levels, then you might consider using an external GPS. Visit our Buying Guide page for more details on recommended iPad models and GPS accessories.


    Why can't I get a good location fix?

    Please view these tips. If you are using a first generation iPhone or an iPod touch (or the wifi-only iPad) then a location can only be determined when you are near cellular and/or WiFi stations. Even when that is the case, your location may be off by as much as a few miles. On the newer iPhones (3G, 3GS, and 4) and the iPad 3G the built-in GPS receiver gives much better and faster location information, however GPS only works when you are near a window or outside. This GPS receiver is required in order to show speed, course, and altitude.


    Can I use barometric pressure to correct the GPS altitude?

    If you have an iPhone 6, 6+, an iPad Air 2 and newer, or a Stratus 2S, you will be able to see Pressure Altitude in the Instrument Panel within ForeFlight Mobile.  What is displayed will be the pressure altitude as sensed by the barometer sensor.  This altitude, however, is currently based on the standard atmosphere of 29.92 in hg (1013.25 Hpa).  Because of this, pressure altitude will not always indicate your correct altitude above Sea Level.  The barometric pressure can not be used to adjust GPS altitude displayed within ForeFlight Mobile.

    Of interest, the altimeter in your aircraft is measuring a pressure level, not necessarily altitude above mean sea level.  GPS altitude is a geometric altitude, which is a measurement of your actual altitude above the earth.

    Pressure altitude and GPS altitude differ more and more the higher you climb (as they are measuring different things).  To learn more, here is an well written article on pressure altitude vs. GPS altitude:

    Will the Flight Guide Fly-Wi GPS receiver work with ForeFlight?

    The Flight Guide Fly-Wi GPS receiver does not work with ForeFlight.  You can use any external Bluetooth GPS receiver that is certified by Apple as MFi (Made For iPad, iPhone, or iPod). The Stratus ADS-B external receivers also provide GPS information to ForeFlight using a Wi-Fi connection. Please review our buying guide for the latest recommended gear.

    What does "Direct Connection" mean for bluetooth GPS devices like the Dual or Bad Elf?

    "Direct Connection" means that ForeFlight Mobile will bypass the normal method of communicating with the GPS. This is helpful if the device shows as "connected" in System Settings but is not working in the app. When "Direct Connection" is used, the device name will show in the Accuracy instrument at the bottom of the Maps view.

    The switch for managing "Direct Connection" is available when connected to the device. Use the Devices view in ForeFlight Mobile and tap the bluetooth GPS to view its details and settings.

    When "Direct Connection" is off, the GPS signal will be of the exact same quality/accuracy/frequency even though the Accuracy readout on the Maps view in ForeFlight Mobile may show a higher value. That higher value is simply due to reporting limits in iOS, and does not reflect that the accuracy is, in fact, much better.

    The recommended setting is "Direct Connection" OFF whenever possible. That will maximize the speed and reliability of the app without compromising GPS fix quality in any way.


    Can I feed GPS data from a flight simulator into ForeFlight?

    Yes! If you are the developer of a flight simulator and would like to integrate its GPS and/or traffic feed into ForeFlight Mobile, this page describes how.
