Chapter 11: Communication & Navigation › Instrument Landing Systems (ILS) › Marker Beacons
Figure 11-110. Components of an instrument landing system (ILS). Some ILS approaches have an inner marker beacon that transmits a signal modulated with 3000 Hz in a series of dots only. It is placed at the land ... usually incorporate marker lights or indicators close to the glideslope display near attitude director indicator. [Figure 11-117] ILS radio components can be tested with an ILS test unit. Localizer, glideslope, and marker beacon signals are generated to ensure proper…

Chapter 11: Communication & Navigation › Radio Navigation › VOR Navigation System
part of the same avionics unit as the VHF communication transceiver(s). These are known as NAV/ COM radios. Internal components are shared since frequency bands for each are adjacent. [Figure 11-99] Figure 11-95. A VOR ground station…

Chapter 11: Communication & Navigation › Reducing Radio Interference › Shielding
control systems, AC power lines, and voltage regulators all produce potential damaging fields. Shielding wires to electric components and ignition systems dissipates radio frequency noise energy. Instead of radiating into space, the braided conductive shielding guides unwanted current flows ... ground. To prevent the build-up of electrical potential, all electrical components should also be bonded to the aircraft structure (ground). Figure 11-159. A bonding jumper is used to ground an equipment rack and avionics chassis around…
