Airspace Management & NOTAMs Flashcards

What is the correct process for a commercial drone operator to obtain airspace permission to fly within a controlled aerodrome's ATZ?

Answer: Contact the aerodrome's air traffic control (ATC) or AFIS unit directly and obtain verbal or written permission before flight

To enter an Aerodrome Traffic Zone, the drone operator must contact the ATC or AFIS unit responsible for that aerodrome and receive explicit permission. This permission is usually verbal, and the operator should record details in their flight log. Some aerodromes may require advance notice.

Where can a commercial drone operator obtain official NOTAMs for pre-flight airspace planning?

Answer: The NATS NOTAMam service, the CAA AIS portal, or CAA-approved drone apps that aggregate NOTAM data

NOTAMs are publicly accessible through NATS (National Air Traffic Services) AIS (Aeronautical Information Service) and the CAA's information portals. Multiple approved drone apps such as Altitude Angel and NATS Drone Assist aggregate this data in a more user-friendly format for drone pilots.

A NOTAM contains the time code 'B) 2603151400 C) 2603151800'. What does this indicate?

Answer: The restriction is active from 14:00 UTC on 15 March 2026 to 18:00 UTC on 15 March 2026

NOTAM time codes use the format YYMMDDHHMM in UTC. B) indicates the start time and C) the end time. So B) 2603151400 = 14:00 UTC on 15 March 2026, and C) 2603151800 = 18:00 UTC on 15 March 2026. Drone pilots must decode these correctly to determine when restrictions are active.

What is Airspace Coordination Notice (ACN) in the context of commercial drone operations?

Answer: A system for drone operators to notify ATC of planned operations in certain airspace, improving awareness for both parties

Some drone operators use coordination notices or formal pre-notification systems (such as those offered through drone traffic management platforms) to share flight intentions with ATC and other airspace users. This voluntary coordination improves safety by reducing surprise encounters between drones and manned aircraft.

What does 'Class D' airspace mean for a commercial drone operator planning a flight?

Answer: Controlled airspace where ATC clearance is required; drone operators must contact the relevant ATC unit and receive permission before entry

Class D is controlled airspace, commonly surrounding busy regional airports and approach paths. All aircraft, including drones, require ATC clearance to enter. Commercial drone operators must establish two-way radio communication or an approved equivalent and obtain clearance before operating in Class D.

What is U-space in the context of UK drone airspace management?

Answer: A framework of digital services designed to support safe drone integration into airspace, including registration, geofencing, and traffic management

U-space is a set of services and procedures designed to allow safe and efficient access to airspace for large numbers of drones. It includes services such as drone registration, flight authorisation, weather information, geofencing enforcement, and drone traffic management — enabling coexistence of manned and unmanned traffic.
