2.6 LAANC and Airspace Authorization

LAANC and Airspace Authorization

The Low Altitude Authorization and Notification Capability (LAANC) is the FAA's automated channel for granting drone authorizations in controlled airspace. It is the tool you will use most often in the field and a reliable source of exam questions.

What LAANC Is

LAANC is a partnership between the FAA and approved private companies that:

• Automates the application and approval of airspace authorizations.
• Returns approvals in near-real time, frequently within seconds.
• Operates through FAA-approved third-party apps such as Aloft, Airspace Link, and others.
• Covers roughly 726 airports and the associated ATC facilities nationwide.
• Serves both Part 107 pilots and recreational flyers (who must also pass TRUST), and has served recreational flyers since July 2019 (not 2024).

How a LAANC Request Flows

1. Request: enter your area, altitude, date, and time window in an approved app.
2. Automated cross-check against the FAA UAS Data Exchange: UAS Facility Maps, active TFRs, NOTAMs, Special Use Airspace, and airport/airspace-class data.
3. Decision: if the requested altitude is within the map's ceiling for every cell you cover, approval is automatic and near-instant.
4. Fly: operate within the authorized area, altitude, and time window only.

UAS Facility Maps (the Backbone)

UASFMs define, per grid cell, the highest altitude LAANC can auto-approve:

The FAA updates these maps periodically based on traffic analysis around each airport. Cells nearest the runways are lowest; cells far from the approach and departure paths trend toward the full 400 ft.

When LAANC Cannot Help

The Manual DroneZone Process

When automation falls short, use the FAA DroneZone portal (faadronezone-access.faa.gov):

1. Submit a detailed request describing the operation.
2. Plan for processing that has historically taken up to eight weeks — start early.
3. The FAA can grant altitudes above the UASFM ceiling when the operation justifies it.
4. Approval typically carries specific conditions you must honor.

Worked Scenario

You need 350 ft AGL for a roof inspection inside Class D. The UASFM shows 200 ft for that cell. LAANC will auto-approve only up to 200 ft. To reach 350 ft you submit a LAANC further coordination request at least 72 hours ahead (an air traffic manager reviews it) or a DroneZone request weeks ahead, or you re-plan the mission to stay at or below 200 ft and get a near-real-time LAANC approval.

Best Practices and Traps

• Request before you arrive — do not gamble on field-side approval.
• Read the UASFM during planning so you know the ceiling before you commit.
• A LAANC approval is not a Part 107 waiver: it grants airspace access only; the 400 ft AGL ceiling, VLOS, and weather minimums still apply.
• Common trap: thinking LAANC’s automatic approval reaches above the map ceiling. It does not; above the map (up to 400 ft) you need a further coordination request, reviewed by an air traffic manager and submitted at least 72 hours ahead, or a DroneZone request.

Authorization vs. Waiver — A Distinction the Exam Tests

Candidates routinely confuse an airspace authorization with a Part 107 waiver, and the difference is worth nailing down. An authorization, whether through LAANC or DroneZone, simply grants permission to enter controlled airspace; it does not relax any operating rule. A waiver (filed through the FAA’s Aviation Safety Hub) is a separate instrument that permits operating outside a specific Part 107 rule — for example, flying beyond visual line of sight or over people without meeting the standard category requirements.

The exam likes to ask which document you need: to enter Class D you need an authorization; to fly beyond VLOS you need a waiver. Mixing these up is a frequent error because both used to be filed in the same DroneZone portal.

Picking and Trusting a LAANC Provider

LAANC is delivered through FAA-approved third-party apps rather than a single FAA website, so the practical workflow is to keep one trusted app installed and verified before heading out. When you submit, the app cross-references the live UAS Data Exchange, so a TFR that popped up an hour ago will block the approval even if your chart is current. This is why a LAANC check doubles as a partial TFR check — but it does not replace a dedicated NOTAM and TFR review, because not every restriction flows through the same feed. Treat LAANC as your airspace gatekeeper and the FAA NOTAM system as your independent confirmation.

Worked Scenario

You arrive at a Class D site and your LAANC app returns an instant approval to 200 ft AGL valid for the next four hours. Mid-shoot you realize you need to drift the operation half a mile and climb to 250 ft. Because both changes push you outside the granted area and altitude, the original approval no longer covers you; you must submit a new LAANC request for the new cell and altitude before repositioning. If the new cell shows 0 ft, you stop and re-plan rather than fly on the expired terms. The exam rewards the pilot who understands that an authorization is bounded by its exact area, altitude, and time window.
