Frequently Asked Questions

Skylicence Europe is an AI-powered web application designed to help aircraft maintenance students and certifying staff prepare for the EASA Part-66 basic knowledge examinations.

It covers all licence categories — A, B1.1, B1.2, B1.3, B1.4, B2 and B3 — across the 17 Part-66 modules (Mathematics to Propeller), with realistic module simulations, detailed explanations, and an AI tutor.

All eight Part-66 licence categories:

• A — Line Maintenance (aeroplane turbine and piston)
• B1.1 — Aeroplane Turbine
• B1.2 — Aeroplane Piston
• B1.3 — Helicopter Turbine
• B1.4 — Helicopter Piston
• B2 — Avionics
• B3 — Light Helicopters and Small Aeroplanes

Each category maps to its official module matrix (which modules you must pass) and the Appendix II exam specs.

Skylicence Europe adjusts question difficulty based on your performance:

• Score 80% or higher on a set of questions → difficulty increases (EASY → MEDIUM → HARD)
• Score below 50% → difficulty decreases

This ensures you are always studying at the right level to maximise learning efficiency.

Skylicence Europe is a web application optimised for desktop and mobile browsers. You can study anywhere, anytime from your phone, tablet, or computer — no app download required. The responsive design adapts to any screen size.

The AI Tutor is an interactive chat feature that helps you understand difficult concepts. When you encounter a question you do not understand, you can ask the AI Tutor for a simplified explanation.

It uses AI to break down complex Part-66 topics — from electrical fundamentals to gas turbine engine theory — into clear, digestible answers.

The Part-66 basic knowledge syllabus has 17 modules:

• 1 Mathematics
• 2 Physics
• 3 Electrical Fundamentals
• 4 Electronic Fundamentals
• 5 Digital Techniques
• 6 Materials and Hardware
• 7 Maintenance Practices
• 8 Basic Aerodynamics
• 9 Human Factors

• 12 Helicopter Aerodynamics/Structures/Systems
• 13 Aircraft Systems (B2)
• 14 Propulsion (B2)
• 15 Gas Turbine Engine
• 16 Piston Engine
• 17 Propeller

Each module has an official question count and time limit per category (Appendix II), and the pass mark is 75%.

No — you only pass the modules required for your licence category. For example, B1.1 (aeroplane turbine) requires 13 modules, B2 (avionics) requires 12, and B3 requires 13.

Skylicence Europe shows the exact module matrix for your category so you know precisely what to study.

Per the official Appendix II examination standard, essay questions are included in:

• Module 7 (Maintenance Practices) — 2 essays
• Module 9 (Human Factors) — 1 essay
• Module 10 (Aviation Legislation) — 1 essay

All other modules are multiple-choice only.
