European Union
The A1/A3 test is the one almost every European pilot takes first. These ten questions come from the same bank the app uses, and each answer names the article it rests on.

Formats and fees move. Confirm both with the authority before you book, because the authority is the only source that counts.
Pick an answer and the page tells you straight away whether it was right, then shows the reasoning and the rule. There is no sign-up and no score to keep, so you can start over as often as you like.
1In the open category, what is the remote pilot's general obligation with respect to manned aircraft?
A. The remote pilot must give way to manned aircraft and avoid any risk of collision
The remote pilot is required to give way to manned aircraft and to take whatever action is needed to avoid a collision. This reflects the general principle that a small UAS is far more manoeuvrable and easier for its pilot to reposition than most manned aircraft.
Regulation (EU) 2019/947, UAS.OPEN.060
2In simple terms, what is the key difference between controlled and uncontrolled airspace?
C. Controlled airspace has defined boundaries where air traffic control provides a service to manned aircraft, while uncontrolled airspace generally does not
Controlled airspace has defined lateral and vertical boundaries within which air traffic control provides a service to aircraft operating there, while uncontrolled airspace generally does not have this service. Understanding this distinction helps a remote pilot appreciate why some areas carry additional restrictions or authorisation requirements for UAS.
Regulation (EU) 2019/947, Article 15
3EU drone regulation establishes three categories of UAS operation. What are they?
D. Open, specific and certified
UAS operations across the European Union are performed in one of three categories: open, specific or certified, corresponding broadly to increasing levels of risk and regulatory oversight. The open category, covered by this exam, is the lowest risk tier with the fewest individual authorisation requirements.
Regulation (EU) 2019/947, Article 3
4How can fatigue affect a remote pilot's ability to safely operate a UAS?
B. It can slow reaction time, reduce concentration and impair judgement, increasing the risk of an error
Fatigue is well documented to slow reaction time, reduce concentration and impair judgement, all of which increase the likelihood of an error during a flight. A tired remote pilot faces the same kind of performance degradation as any other pilot, and should treat significant fatigue as a reason to reconsider flying.
Regulation (EU) 2019/947, UAS.OPEN.060
5What is the general purpose of the C0 to C4 class identification marking system for UAS?
B. To indicate that an aircraft meets a defined technical standard, which in turn determines which open subcategories it is eligible to fly in
The class mark indicates that a UAS meets a specific technical standard defined in the product regulation, and this class in turn determines which open category subcategories the aircraft is eligible to be flown in. It says nothing about manufacturing country, price or ownership history.
Regulation (EU) 2019/945 Part 1
6A UAS operator fits a camera to their aircraft and records footage that includes identifiable people. What legal framework generally applies to this data, in addition to UAS specific regulation?
A. EU data protection legislation, since footage of identifiable individuals is personal data
Footage that shows identifiable individuals counts as personal data, which brings it within the scope of EU data protection legislation in addition to whatever UAS specific aviation rules apply. Fitting a camera to a UAS therefore introduces a distinct set of legal obligations on top of the operational ones.
Regulation (EU) 2016/679
7What is the general purpose of Regulation (EC) 785/2004 in relation to aircraft, including UAS, operating within its scope?
A. To set minimum insurance requirements so that victims of an accident have access to adequate compensation
Regulation (EC) 785/2004 sets minimum insurance requirements for aircraft operators so that anyone harmed in an accident has access to adequate compensation. It is an insurance regulation, not one that governs speed limits, pilot training certification or technical class marking.
Regulation (EC) 785/2004
8Why should a remote pilot take reasonable steps to prevent their UAS and controller from being stolen or accessed by unauthorised people?
C. An unsecured aircraft or controller could be used irresponsibly or unlawfully by someone other than the registered operator
An aircraft or controller that is stolen or accessed without authorisation could be used irresponsibly or unlawfully by someone who is not the registered operator, potentially creating safety or security problems that would then be traced back to the original owner. Reasonable physical security measures, such as not leaving equipment unattended, reduce this risk.
Regulation (EU) 2019/947, UAS.OPEN.020
9Why should airspace scanning for other traffic continue throughout an open category flight, rather than being treated as a single check performed before launch?
D. Other aircraft can enter the area at any point during the flight, so ongoing awareness is needed to maintain safe separation
Traffic conditions can change at any moment during a flight, with other aircraft entering the area well after takeoff, so a one time check before launch does not remain valid for the whole flight. Continuous scanning is part of the remote pilot's ongoing duty to maintain safe separation.
Regulation (EU) 2019/947, UAS.OPEN.060
10Why is following a consistent pre-flight checklist considered good operational practice, rather than relying on memory alone each time?
C. A checklist reduces the chance of forgetting an important step, even when the pilot is experienced or distracted
A consistent checklist provides a reliable structure that reduces the chance of forgetting an important step, regardless of how experienced the pilot is or how distracted they might be on a given day. Memory alone is more prone to lapses, particularly under time pressure or after many repetitions of a familiar task.
