Airspace authorization and LAANC

Airspace is three-dimensional. A map pin alone does not answer the question: determine the exact site, planned altitude, nearby boundaries, and the vertical limits of each airspace layer. Part 107 generally requires prior ATC authorization for operations in Class B, C, and D airspace and within the lateral boundaries of the surface area of Class E designated for an airport. Other airspace may not need that particular authorization, but restrictions, TFRs, national security areas, and local operational hazards can still apply.

Class B, C, and D areas commonly relate to towered airports, but visual appearance or tower status alone is not a reliable classification. Class E can extend to the surface at certain airports; on a sectional chart, the magenta dashed boundary is a key clue. Class G is uncontrolled airspace, but 'uncontrolled' does not mean risk-free or unrestricted. Use the current sectional, chart supplement when needed, FAA UAS Facility Map, NOTAMs, and official authorization tools together.

Low Altitude Authorization and Notification Capability (LAANC) automates qualifying requests in participating areas. UAS Facility Map grid values show altitudes at which authorization may be available through LAANC; they are not automatic permission to fly at that altitude. A request is not an approval. Wait for the actual approval and review its geographic footprint, maximum altitude, effective time, and any conditions before launch. In some circumstances, a further coordination request can be submitted, but approval is not guaranteed.

Where LAANC is unavailable or a request does not fit its automated parameters, use the FAA's current DroneZone process or other FAA-published route for airspace authorization. Processing times and procedures can vary, so plan ahead. The authorization is tied to the specified operation; moving a few blocks or changing altitude can cross into another grid or airspace volume. Confirm location precision, datum, altitude reference, and time zone when translating a work order into a request.

An airspace authorization is different from a waiver. Authorization permits a specified flight in controlled airspace; a waiver grants relief from a listed Part 107 provision subject to its conditions. You may need both for one mission, and neither necessarily covers the other issue. A waiver cannot replace a separate airspace authorization when one is required. A property owner's consent likewise does not grant access to controlled airspace or override a federal restriction.

Check NOTAMs and temporary flight restrictions close to the operation because status can change after a request is approved. Review special-use airspace and security-sensitive sites carefully, and follow current FAA guidance where boundaries overlap. Preserve the approval and brief the crew on abort conditions if the aircraft approaches a limit. If electronic tools conflict or the operating area is ambiguous, stop and resolve the discrepancy with authoritative FAA information before takeoff.
