062 ATPL subject guide
Radio Navigation
Radio Navigation rewards students who understand what the aid is actually measuring and what can distort or limit the indication. Memorising acronyms alone is not enough.
Difficulty
Hard
What the paper tests
Mixed theory, signal behaviour, and equipment use
Why it matters
The subject combines signal behaviour, equipment interpretation, and operational usage. Questions often probe the limitations of the navigation aid rather than the definition alone.
Best next step
Use timed practice and spaced recall together so weak areas come back before they decay.
Key topics
- VOR, DME, NDB, and ADF principles and errors
- ILS, marker beacons, radar, GNSS, and RNAV concepts
- Signal propagation, range limitations, and operational application
How to study it
- Study each navaid through signal source, cockpit indication, and limitation.
- Use comparison tables so you stop mixing look-alike aids and errors.
- Practise operational interpretation, not just theory definitions.
Common traps
- Confusing what the station transmits with what the aircraft equipment computes.
- Forgetting limitations such as slant range, line of sight, or atmospheric distortion.
- Treating GNSS and RNAV as identical concepts in every context.
