Drone Theory Test Study Guide for the UK

Why There Is No Single Answer Sheet

If you have searched for the exact answers to the CAA drone theory test, you should know that the question bank rotates. Each time you take the test, the specific questions may differ from a previous attempt. Publishing a fixed list of answers would be unreliable and potentially misleading.

The good news is that the test is open book. You are allowed to look up information while answering, so thorough preparation is more about knowing where to find the right information than memorising every possible question. The CAA designed the test as a learning tool, not a trick exam.

With 20 multiple-choice questions and a pass mark of 16/20, you can afford up to four mistakes. If you understand the core principles outlined below, you should pass comfortably.

Essential Knowledge: Altitude and Airspace

Altitude rules appear frequently in the theory test. The key figures to know are:

• Maximum altitude: 120 metres (400 feet) above ground level for most drone operations in the Open category
• Flight Restriction Zones (FRZs): Protected airspace around airports and airfields where drone flight is either prohibited or heavily restricted. You must check for active FRZs before every flight
• NOTAMs (Notices to Air Missions): Temporary restrictions that may apply to specific areas. Check NOTAMs before flying, as they can create new no-fly zones at short notice

A common mistake is confusing the altitude limits between different drone categories. In the Open category, 120 metres is the absolute ceiling. Some questions may reference the Specific category, which can involve different altitude permissions under an operational authorisation — but for the Flyer ID test, the Open category rules are the primary focus.

Essential Knowledge: Distance and Separation Rules

Questions about how far your drone must be from people, buildings, and congested areas are a staple of the test. The specific distances depend on your drone's class and subcategory:

• Open A1 subcategory: Drones under 250g can fly over uninvolved people (but not crowds). Heavier class-marked drones can fly near but not over uninvolved people
• Open A2 subcategory: Must maintain at least 30 metres horizontal distance from uninvolved people (reducable to 5 metres at low speed with certain drones)
• Open A3 subcategory: Must fly in areas where no uninvolved people are expected, and maintain 150 metres from residential, commercial, industrial, or recreational areas

Make sure you understand which subcategory your drone falls into. The test may present scenarios where you need to identify the correct minimum distance for a given situation.

Essential Knowledge: Privacy and Data Protection

The Data Protection Act 2018 applies whenever your drone captures images or video that could identify individuals. Key points the test may cover include:

• You must have a lawful basis for processing personal data (which includes filming identifiable people)
• The Information Commissioner's Office (ICO) provides specific guidance on drones and surveillance
• Flying over private property with a camera can raise privacy concerns even if the airspace above is not restricted
• If someone asks you to delete footage of them, you should understand your obligations under data protection law

Privacy questions are among the most commonly underestimated topics. Many pilots focus heavily on airspace rules and overlook their legal responsibilities around data capture.

Common Mistakes and How to Avoid Them

Based on the topics the CAA emphasises in its guidance material, these are the areas where test-takers most often go wrong:

• Forgetting FRZ checks: Always check for Flight Restriction Zones before flying, not just NOTAMs. FRZs are permanent, while NOTAMs are temporary
• Confusing categories: The Open, Specific, and Certified categories have different rules. The Flyer ID test focuses on the Open category, but questions may reference the others to test your understanding
• Ignoring insurance requirements: While not legally required for all hobbyist flying, insurance is mandatory for any commercial drone operation. Questions about insurance may appear
• Underestimating weather: Wind speed limits, visibility minimums, and the effect of weather on battery performance are all fair game
• Overlooking emergency procedures: Know what to do if you lose signal, if your drone enters a fly-away, or if you need to perform an emergency landing near people

Best Study Resources

The following resources will prepare you thoroughly for the theory test:

• The CAA Drone Code: Available on the CAA website. This is the single most important document to read before sitting the test
• CAA drone guidance pages: The CAA website has detailed sections on each category of drone flying, registration requirements, and operational rules
• The Air Navigation Order 2016: The primary legislation. You do not need to read the entire document, but understanding the key articles that relate to drones is helpful
• Drone community forums: Other pilots share their experience of the test and discuss tricky topics. These can help you identify knowledge gaps

Remember that the test is free to retake with no limit on attempts. If you do not pass on your first try, review the areas where you were uncertain and try again immediately.
