The Cockpit Command Center: A Deep Dive Into Aircraft Avionics
Aircraft avionics are a pinnacle of modern aviation design, coming in the form of various devices that allow pilots to optimally control and monitor various functions of an aircraft. Within this blog, we will provide a brief introduction to common types of avionics that are found in typical aircraft, exploring their functions, evolution, and maintenance considerations. This information will provide the insight necessary to find optimal solutions for projects, so read on to learn more.
What are Avionics?
Aircraft avionics are simply aviation electronics, encompassing the various electrical systems that provide pilots with critical information and control capabilities. Avionics have been in use since World War I, with modern aircraft now featuring a wide variety of systems and devices that perform distinct functions.
Common Types of Avionics Found in Aircraft
Navigation Systems
GPS, inertial navigation systems (INS), and radio navigation systems are all forms of avionics that help pilots determine an aircraft's position and guide it along its flight path. Precise navigation is essential for all flights, so such equipment is regularly depended on.
Communication Systems
Communication systems, including VHF radios, HF radios, and satellite communication systems, serve to provide pilots with the ability to communicate with air traffic control and other aircraft.
Fuel Systems
Avionics like the Fuel Quantity Indication System (FQIS) are useful for keeping track of fuel volume, where sensors are leveraged to keep accurate readings. The Fuel Control and Monitoring System (FCMS) is another form of avionic system on aircraft that monitors levels, though it also provides transfer capabilities to move fuel between tanks.
Weather Systems
In order for aircraft to account for potential weather phenomena and make adjustments to maintain optimal flight paths, various forms of weather systems are implemented on modern aircraft. Generally, equipment like weather radars, lighting detectors, and wind shear detectors are common.
From Mechanical to Digital: The Evolution of Aircraft Instrumentation
The Era of Mechanical Instruments
Early aircraft often relied on mechanical instruments to provide pilots with essential flight information. These instruments, which included airspeed indicators, altimeters, and compasses, used physical mechanisms to measure and display flight parameters. While reliable, these instruments would often require increased maintenance and made information gathering a more complex process.
The Integration of Digital Avionics
With the development of microprocessors and advanced electronics over the past few decades, digital avionics systems emerged to replace traditional mechanical gauges and displays. These systems often integrate various functions, such as navigation, communication, and flight control, into a unified platform, increasing efficiency, reducing pilot workloads, and enhancing safety.
How to Troubleshoot Aircraft Avionics
Troubleshooting aircraft avionics generally requires a systematic approach and a thorough understanding of the systems being worked on.
The Basic Troubleshooting Process
A typical troubleshooting process will involve identifying the reported problem with the use of equipment, gathering information on the issue, performing tests, and isolating the faulty component. A logical approach is essential so that nothing is overlooked or improperly done.
Using Maintenance Manuals and Diagnostic Tools
Maintenance manuals and proper diagnostic tools are essential resources for carrying out troubleshooting for aircraft avionics. These resources will often provide detailed information about the systems and safe procedures for testing them.
Importance of Proper Training
Proper training is crucial for technicians who troubleshoot aircraft avionics, as such systems are often complex and require specialized knowledge to service.
