Radio wave Propagation Radio Wave Transmission Radio waves propagate or travel as Ionospheric and Non-ionospheric propagation Ionospheric layer is found in the upper levels of stratosphere in atmosphere Radio waves travel or propagate with or without use of Ionosphere Non-Ionospheric propagation takes place without use of ionosphere Ionospheric propagation takes place using the ionospheric layer Non Ionospheric Propagation Non-Ionospheric propagation does not pass through Ionosphere Ground waves propagate without passing through Ionosphere Ground waves are sub-divided into Surface and Space waves Surface Waves Low, Medium and High Frequency waves from…

Radio Aids for Navigation is an important subject for Student Pilots. In this section, you can learn about the various Radio Navigational Equipments used in Aviation.
Electro-Magnetic Waves (EM Wave)
Electro-Magnetic Waves Electrical and Magnetic Field in EM Waves EM waves are created by movement of Alternating current (AC) in a wire Radio aids in aviation use Electro Magnetic Waves (EM Waves) Alternating current creates a magnetic field perpendicular to electric field EM Radiation is transmitted through air if the wire is connected to an Ariel EM Radiation consists of electrical and magnetic components Electrical field in the same plane of the ariel Magnetic field perpendicular to the electrical field Electro Magnetic Spectrum EM waves has a wide spectrum with…
