The EASA ATPL062 radio-navigation foundations study guide has 3 sections and about 1,352 words.
01Conventional radio aids and displayed guidance
Radio navigation requires separating a transmitted signal, the quantity derived from it and the instrument presentation. A correct frequency or familiar symbol is not enough to establish that a facility is suitable, identified and available for the intended use. This foundation bank teaches principles and interpretation. It does not replace current charts, notices, aircraft documentation or an approved instrument procedure.

Satellite navigation combines signal measurements, a position solution and information about whether that solution meets the required use. Seeing plausible coordinates does not establish accuracy, integrity or approval for an instrument procedure. Separate the receiver’s capability from its current performance, installation eligibility, database and operational requirements. These are related checks, not interchangeable labels.

Radio signals interact with frequency, geometry, terrain and the receiving installation. Many VHF and UHF aviation applications are largely limited by line-of-sight geometry, while lower-frequency or HF signals can involve different surface and ionospheric propagation. A theoretical horizon calculation is a model, not a guaranteed usable range: interference, service volume, terrain, equipment and the required integrity still matter. Wavelength equals propagation speed divided by frequency when units are consistent.
