Key Concepts

Notices to Airmen (NOTAMs) and Their Role in Flight Restrictions

NOTAMs (Notices to Airmen) are the primary system for providing timely information about flight restrictions and hazards. The NOTAM system communicates changes to airspace status, hazards such as temporary flight restrictions (TFRs), or issues like runway closures, special events, disasters, or other time-critical information that is not published on formal aeronautical charts. Before any operation, especially for a remote pilot flying under Part 107, it is essential to review all NOTAMs affecting the proposed flight area to avoid violations and ensure safety[7]. NOTAMs can communicate flight restrictions for high-profile events, wildfires, space launch activities, aerial demonstrations, national security areas, and more.

Failure to comply with flight restrictions disseminated through NOTAMs can result in regulatory violations and enforcement action. For remote pilots, reviewing NOTAMs should be a standard preflight planning step, alongside checking aeronautical charts and weather[6][7]. Flight Service Stations (FSS) and online systems provide NOTAM access during briefings or self-briefings.

Types and Sources of Flight Restrictions Communicated by NOTAMs

Several types of airspace restrictions are designated by NOTAM. Common examples include Temporary Flight Restrictions (TFRs), which may be established for reasons such as natural disasters, movement of dignitaries, large public events, or national security interests[7]. These zones introduce explicit geographic boundaries, altitudes, effective times, and operating limitations. NOTAMs will state who is authorized to operate within the area and under what conditions, if any. Remote pilots must be aware that TFRs are commonly established with very little advance notice.

Airspace near certain government facilities or during special operations may also be subject to restrictions not always charted on permanent maps[7]. NOTAM communication is therefore the authoritative notification for these temporary or rapidly changing areas. The system also relays hazards like aerial firefighting operations, rocket launches, or even wildlife activity near airports[8]. Knowledge of the NOTAM system’s coverage is critical for all pilots, including UAS operators.

Preflight Requirements and Practical Considerations for Drone Pilots

Regulations compel pilots to make themselves aware of all pertinent NOTAMs before flight[6][7]. This means checking NOTAMs must be part of every responsible preflight process, and solely relying on charts is insufficient—charts are only revised on regular cycles, while NOTAMs can be issued at any time[7]. During FSS-provided preflight briefings, both weather and current NOTAMs will be summarized and tailored to the specific flight plan. However, briefers do not automatically provide all NOTAMs affecting special instrument procedures unless specifically requested, underscoring the importance for pilots to request relevant details[7].

For remote pilots, failing to check for NOTAM-based airspace restrictions could inadvertently lead to airspace incursions, legal penalties, or potentially hazardous situations such as flight into active aerial firefighting operations or proximity to aerial demonstrations. Remote pilots operating near airports should also be alert to NOTAMs about wildlife hazards, temporary closures, and special activity advisories[8].

Pilots are advised to use only the latest issue of aeronautical charts and supplement them with a thorough review of current NOTAMs relevant to their route, area of operation, and time of flight[7]. Only through this comprehensive, habitual check can a drone operator anticipate temporary restrictions, avoid violations, and ensure flight safety.
