Radio Navigation – Index

The discussion on Radio Navigation starts with the basics of Radio waves and propagation. Basic Radar Theory is examined next right from the principles to the airborne use of primary and secondary radar systems. Thereafter, we shall learn about the various Radio Navigational Equipments used in Mordern Aircrafts.

In the category of Radio Navigation, we would understand the principles and use of basic Radio Aids to Navigation like Ground D/F, ADF, VOR, DME, ILS and MLS. Finally, we shall provide a overview of advanced cockpit intrumentation like GPS and FMS. The discussion of radio aids would be covered under the following posts.

  • Properties of Radio Waves
  • Radio Propagation Theory
  • Modulation
  • Antennae
  • Doppler Radar Systems
  • VHF Direction Finder (VDF)
  • Automatic Direction Finder (ADF)
  • VHF Omni-directional Range (VOR)
  • Instrument Landing System (ILS)
  • Microwave Landing System (MLS)
  • Radar Principles
  • Ground Radar
  • Airborne Weather Radar
  • Secondary Surveillance Radar (SSR)
  • Distance Measuring Equipment (DME)
  • Area Navigation Systems (RNAV)
  • Electronic Flight Information System (EFIS)
  • Global Navigation Satellite System (GNSS)

In this post, we have understood the scope of Radio Navigation Syllabus for Pilots. Let us start our discussion of Radio Navigational Aids by understanding about Electro Magnetic Spectrum.
