A2 exam
C4 class drones in the EU framework
Aircraft class and operational category must align - buying the wrong class blocks legal flights.
Contents
1. What C4 means
C4 is a manufacturer assurance class with defined mass and capability limits under open category rules.
2. A1 operations with C4
Typically supports flying over uninvolved persons with light aircraft under strict conditions - read your manual.
3. When A2 is still required
Heavier missions near people with C2 aircraft need A2 competency - class alone does not replace certificates.
4. Exam relevance
Questions contrast classes C0-C4 and link to subcategories - study comparison tables.
5. Buying advice
