LAANC: The Complete Guide to Drone Airspace Authorization

Flying in controlled airspace -- Class B, C, D, and some Class E -- requires authorization from the FAA. Before LAANC, that authorization took days or weeks and involved paperwork. LAANC changed that: most controlled airspace authorizations are now available in under a minute, through a phone app.

Understanding how LAANC works, where it applies, and what to do when it does not apply is fundamental knowledge for any drone pilot -- recreational or Part 107.

What LAANC Is

LAANC stands for Low Altitude Authorization and Notification Capability. It is a collaboration between the FAA and approved UAS Service Suppliers (USS) that provides automated airspace authorization for drone operations below published altitude limits in designated grid cells.

The system works because the FAA has pre-defined altitude ceilings for drone operations at specific locations -- the LAANC facility maps. These maps divide controlled airspace into grid cells with published maximum altitudes ranging from 0 to 400 ft AGL. When you request authorization for an operation within a grid cell at or below the published ceiling, LAANC grants it automatically.

Operations above the grid ceiling, or in grid cells with a 0 ft ceiling, require manual FAA Part 107 authorization through DroneZone -- the traditional process that can take 90 days.

How to Get LAANC Authorization

Step 1: Check the LAANC facility map. Before using any app, look up the LAANC facility map for your area. The FAA publishes these maps at faa.gov/uas/programs_partnerships/data_exchange. The map shows which airports participate in LAANC and the altitude ceiling for each grid cell.

UAS SkyCheck shows LAANC availability and the altitude ceiling for any checked location. A check result showing "LAANC Available" with a ceiling of 200 ft means you can request authorization through any USS app for operations up to 200 ft AGL at that location.

Step 2: Request authorization through a USS app. The FAA approves the UAS Service Suppliers that grant LAANC, and the FAA keeps the current list at faa.gov/uas/getting_started/laanc. Providers have joined and left the program since it opened, so the FAA's page is the place to look rather than a name remembered from a forum post. Every approved app requests against the same FAA facility-map data and grants the same authorization; pick one that runs on your phone, create the account before you are standing in the field, and expect a near-real-time authorization under the cell's ceiling in well under a minute.

Step 3: Complete the authorization form. The app will ask for your operation area (GPS coordinates or map selection), planned altitude, date and time, duration, and your FAA registration number. Accuracy matters -- the authorization is valid only for the parameters you submit.

Step 4: Receive authorization. Standard LAANC authorizations arrive in seconds via email and in-app notification. Save the authorization record -- you are required to have it available during the flight.

What LAANC Covers and Does Not Cover

LAANC covers:

• Operations in designated LAANC facility map grid cells at or below the published altitude ceiling
• Both Part 107 commercial operations and recreational operations
• Same-day and advance authorizations (you can request future-dated authorizations)

LAANC does not cover:

• Operations above the grid cell altitude ceiling (requires Part 107 manual authorization)
• Locations not covered by a LAANC-participating facility (requires manual authorization or operations are in Class G)
• Active TFRs -- LAANC authorization does not override a TFR
• National parks, wildlife refuges, and other land-based restrictions
• Waivers for operations that violate Part 107 limitations

Key point: LAANC provides airspace authorization. It does not resolve restricted zones, TFRs, or any other restriction. A LAANC authorization in a location with an active TFR is not valid for that operation.

LAANC Grid Cells and Altitude Ceilings

The altitude ceiling in any given grid cell reflects what the FAA has determined safe for drone operations at that location relative to manned aircraft traffic patterns.

• 400 ft ceiling: Areas away from final approach paths and departure routes. Operations to the standard Part 107 maximum.
• 200 ft ceiling: Moderate proximity to airport operations. Most common ceiling near Class C and D airports.
• 100 ft ceiling: Closer proximity to traffic patterns or busier airspace.
• 50 ft ceiling: Near the airport boundary or approach paths.
• 0 ft ceiling: No automated authorization available. Manual authorization required through DroneZone.

When your planned altitude exceeds the LAANC ceiling, you have two options: fly at or below the ceiling, or apply for manual authorization.

When LAANC Is Not Available

Some controlled airspace does not participate in LAANC, some airports have 0 ft ceilings throughout, and some specific locations require manual authorization regardless of the general LAANC grid.

Manual Part 107 authorization (DroneZone). Applications are submitted at faadronezone.faa.gov. The process requires a detailed description of the operation, proposed coordinates and altitude, safety justification, and contact information. Standard processing is 90 days, but some authorizations are reviewed faster depending on the facility and the complexity of the request.

For operations that are time-sensitive, apply for manual authorization as far in advance as possible. Some facilities have standing processes for common operation types (tower inspection, construction monitoring) that move faster than completely novel requests.

Checking with the ATCT. For operations near an airport with an operating control tower, calling the tower directly is sometimes the fastest path for simple, short-duration operations at low altitude. Not every controller will coordinate this way, and it is not a substitute for formal authorization, but it is worth understanding as an option for straightforward situations.

Authorization Record-Keeping

Under Part 107, you must have your authorization documentation available during the flight. For LAANC authorizations, this means:

• The authorization email from the USS app
• Or the in-app authorization record

Have your phone charged and the authorization accessible if asked by law enforcement or FAA personnel. An authorization you cannot produce during the operation is functionally the same as no authorization from an enforcement standpoint.

Record the authorization in your flight log alongside the flight details. Captain-tier pilots can note authorization status in UAS SkyCheck's flight log entries.

Recreational Pilots and LAANC

LAANC is available to recreational pilots operating under 44809 as well as Part 107 certificate holders. The authorization process is the same through the same apps. Recreational pilots must still obtain LAANC authorization before flying in controlled airspace -- the recreational exemption does not eliminate airspace authorization requirements.

When Your LAANC Authorization Is Denied

Automatic LAANC denial occurs when:

• Your requested altitude exceeds the grid cell ceiling
• The grid cell has a 0 ft automated ceiling
• A TFR is active in the area (LAANC systems check for active TFRs)

If automatic authorization is denied, review the reason and either adjust your operation parameters (lower altitude, different location) or apply for manual authorization if the operation is essential.

UAS SkyCheck shows LAANC availability, altitude ceilings, and the authorization status for any location in a single check. Verify before every controlled airspace flight at uas-skycheck.app.
