FAA Airspace Authorization Grid Maps for Class E Airspace

In FAA Part 107, Waiver & Airspace Authorization by Enrico Schaefer

The FAA has made good on its promise to start releasing grid maps for controlled airspace, starting with lateral boundaries of Class E. Because drone pilots need airspace authorization to fly in Class B, C, D and lateral E, and because ATC permission through the FAA website is often painfully slow and uncertain, Part 107 drone pilots have been hampered in their efforts to launch successful and profitable drone services. What customer wants to wait weeks or months to learn the FAA won’t allow a flight at a certain location?


We will be writing more about the grid maps in coming days. For now, here is the link to the Class E airspace grid maps.  Zoom into your location and see if, and at what altitude, you can fly your drone. And understand you still need ATC permission, obtained through the FAA website here.  These grid maps are designed to make it easier for you to know ahead of time if the answer will be ‘no.’ and what altitude you are likely to receive permission.  This will make your requests for airspace authorization more standardized, and predictable.

Below is what a grid map looks like when you zoom in on the map.  You can see that areas around Pellston Airport indicate “0” feet.  Does this mean the FAA will not ever let you fly your drone at these locations?  Luckily, the answer is ‘no.’   This means you you can’t fly at these locations without additional risk mitigation measures included in your airspace authorization request.    [see blow for comments from the FAA news release discussing the grid maps].

Here is what the FAA said about the grid maps:

  • The maps depict areas and altitudes near airports where UAS may operate safely. But drone operators still need FAA authorization to fly in those areas.
  • The maps are informational and do not give people permission to fly drones. Remote pilots must still submit an online airspace authorization application.
  • The map viewer displays numbers in grid cells which represent the distances Above Ground Level (AGL) in one square mile up to 400 feet where drones may fly. Zeros indicate critical locations around airports and other aircraft operating areas, like hospital helipads, where no drone flights can be preauthorized.
  • Requests to operate in these areas will require further coordination and FAA safety analysis, which can result in additional safety mitigations to be complied with by the drone operator.
  • Remote pilots can refer to the maps to tailor their requests to align with locations and altitudes when they complete airspace authorization applications.
  • Altitudes that exceed those depicted on the maps require additional safety analysis and coordination to determine if an application can be approved.
  • Additional maps will be published every 56 days through the end of the year. The updates will coincide with the agency’s existing 56-day aeronautical chart production schedule (PDF). If a map is not yet available, it can be expected in future releases.
  • The next grid maps should be released on: 25-May, 22-Jun, 20-Jul

The digital maps being made public through the FAA UAS Data Delivery System include a grid overlay that depicts acceptable altitude limits for UAS operations near airports around the country. Remote pilots should use these maps to plan drone operations and drafting their submissions for airspace authorization requests.  We presume that requests that fall within the grid map parameters on location and altitude will  be more likely to achieve rapid approval by the FAA.
