creatre all of the following modules and lessons in uk english please. do not change the couse structure=What is RNAV?
Area Navigation (RNAV) defined

Difference between conventional navigation and RNAV

Role of waypoints and navigation specifications (e.g., RNAV 1, RNAV 5)

Key advantage: aircraft can fly direct routes, not limited to ground navaids

📝 Quick Quiz: Why is RNAV more flexible than traditional ground-based navigation?

🟦 Module 2: The Technical Backbone – Satellite Navigation
What satellites do: trilateration vs triangulation

Space segment (satellites), control segment (ground stations), and user segment (aircraft receivers)

GNSS overview: Global Navigation Satellite Systems

📊 Diagram: Satellite constellation → receiver in cockpit → RNAV route guidance

🟦 Module 3: The Big Four GNSS Providers
GPS (USA): Most widely used; 24–32 satellites; dual-frequency now becoming standard

GLONASS (Russia): Slightly less accurate but provides redundancy; independent ground control

Galileo (EU): Civilian system with high precision; interoperable with GPS and GLONASS

BeiDou (China): Expanding rapidly; regional to global coverage; strong signal reliability

💡 Quick Fact: Most modern FMS systems use multi-GNSS receivers that blend GPS + Galileo + GLONASS.

🟦 Module 4: RNAV in Practice
Flight Management Systems (FMS) and RNAV route loading

RNAV SID/STAR procedures

Required Navigation Performance (RNP) vs RNAV – what’s the difference?

Error types: Path Definition Error (PDE), Flight Technical Error (FTE), and Navigation System Error (NSE)

🧠 Scenario: What happens operationally if a satellite signal is lost mid-flight?
