New Aircraft Avionics installation and functionality - Essay Example It also describes and shows the block diagram, power source wiring, and the electrical cable routing for the three systems. The paper also details the operation and functionality of the remaining two systems in reference to their block diagram, power source wiring, and the electrical cable routing. The report describes the system in depth including the exact functions of the systems, detailing their peripherals and their form of redundancy. The chosen hypothetical avionics systems include communication and navigation system, cabin and cockpit information system, flight instruments (flight recorders), hazard detection system, and surveillance system. Discussion. Communication and Navigation Systems. Receivers and transmitters are widely used in aviation communication and navigation systems. The transmitters and receivers are used together with one ore antennae, which are responsible in implementation of the vital and crucial link between the ground stations, aircrafts, satellites, and other aircrafts. One of the devices used in facilitating navigation and communication is a simple radio communication system. The radio comprises of the receiver and the transmitted that uses the continuous wave signal. Communication is attained through keying or switching the radio frequencies on and off. Switching the radio signal is achieved through interruption of power supple or the oscillator stage, it is usually applicable within the stage of the driver operating at a modest power level. The oscillator stage of keying normally leads to impaired frequency stability. However, the appreciable currents and voltages appearing in the power amplifier stage also prove to be problematic. A simpler CW consists of the radio amplifier, audio amplifier and the detector. The detector stage mixes a domestic generated signal of the radio frequency that is produces by beat frequency oscillator with the coming signals that produces a signal within the radio frequency ranging between 300 Hz an d 3.4 KHz. Antennas are normally used for navigation purposes in aircrafts. There are various practical kinds of antenna used in aviation related applications that include vertical quarter wave antenna, vertical half wave antennas, and also 5/8th wave vertical antennas. Vertical quarter wave antennas produce an omnidirectional radiation pattern in the radiate vertically polarised systems and the horizontal plane. The antennas can be produced for the high HF and VHF bands but the length is prohibitive for usage on the LF bands and low HF (Lombardo, 1993). To produce a flat radiation design it is important to include an effective ground plane. At VHF, it can be attained by employing the 4 quarter wave radial elements. The vertical half wave antennas is voltage fed rather than the current fed. Antennas that are voltage fed requires resonant transformer that is connected between antenna’s end and low impedance coaxial feeder. The arrangement is liable to loses because it needs hi gh quality, and low loss components. It also requires careful adjustment in order to achieve results and therefore they are usually preferred. The5/8th wave vertical antennas offer a compact solution to the essentiality of an Omni-directional VHF. Radio systems: Antennae. Cabin and Cockpit Information Systems In the aviation sector, accessing the correct information in the proper place, at the right period, is important in supporting decisions and enhancing operations. The information system,
