GmapAir is a digital map of U.S. airspaces for VFR flight that is compatible with your GARMIN GPS (Oregon, Colorado, Dakota, nüvi, eTrex, and GPSMAP).

The airspaces, their boundaries, altitude ranges, etc., are presented in an easy-to-understand fashion even for areas where several airspaces overlap.

GmapAir is competitively priced for casual use or as a backup to more specialized aviation GPS devices. It can be particularly useful on craft that are not well instrumented, such as ultralights, hang gliders, paragliders, and balloons.

Click here to see a detailed picture of the airspaces covered by GmapAir. The following categories are covered across the U.S. (including Alaska, Hawaii, and Puerto Rico):

Prohibited, Restricted, Warning, and Alert Areas
Military Operations Areas (MOAs)
Special Federal Aviation Regulation (SFAR) Areas
Class B Airspaces
Class C Airspaces
Class D Airspaces

These are presented on your GPS unit in a manner similar to VFR sectional charts. See Display Sample.

The altitude range (upper and lower limits) of an airspace are displayed on the borderline in two- or three-digit numerical values that represent multiples of 100 feet (MSL).
For instance, the altitude range of an airspace extending from 5000 feet (upper limit) to the surface (lower limit) is presented as "50/S".

If you touch* the display anywhere within the borders of an airspace, GmapAir will display the altitude range, airspace class or type, airspace name, and primary frequency of control authorities.
(in class D / see right)

* For models that do not have a touch-sensitive panel, move the cursor over an airspace and press the ENTER button.

An altitude without a suffix represents the altitude above MSL (Mean sea level), and an altitude with an "a" suffix is AGL (above ground level).
"S" indicates an airspace that extends from the surface.
"U" (Unlimited) indicates an airspace without an upper limit.
The prefix "F" indicates the flight level.
And a minus sign in front of the number indicates that the bounds are not included. (Ex., "-30/-15" means the airspace extends from 2999 feet to 1501 feet.)

Around class B and C airspaces, the VFR approach control frequencies are displayed in a manner similar to VFR sectional charts. If you touch the display over a complex region with several airspaces, you can then select the list button** to view information on all the airspaces in that region on the list screen (see below).

** This operation may vary with the device model.

GmapAir uses the WGS84 coordinates published in the NFD (National Flight Database) by the FAA/NACO (Federal Aviation Administration/National Aeronautical Charting Office). GmapAir is updated every 28 days to synchronize with the NFD. Therefore, the customer will purchase a one-year update of GmapAir (13 issues = USD 32.00).

The current version (date and volume number) of GmapAir is presented at the top line of this page. Once this version is updated, customers can download the latest version from the specified URL at any time. The update schedule may be found at the following link:

As a prerequisite to use the NFD, the FAA requires us to notify all GmapAir customers of a new update or correction to data. In compliance with this requirement, we announce all normal updates on this page and, in the event of an unscheduled correction to data, will send e-mail notifications to our customers.

We do not sell or give away personal information of our customers or publishers. We also do not send promotional e-mail. We will only send you e-mail to notify you about urgent data corrections, as required by FAA regulations, and respond to your questions. Please click here to see our full privacy policy.

Use GmapAir only as an aid for navigation at your own risk.
It is dangerous to rely solely on GPS and electronic devices in flight. Information necessary for flying should be procured from the official government authorities.

Any errors in the NFD will be reflected in GmapAir. If you encounter any such errors, please report them to our support team by e-mail. We will forward this information to the FAA.
