Avionics Technology Crash Course

Avionics are the electronic systems used in spacecraft, artificial satellites and aircraft.

Avionic systems include communications, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions.

One of the hottest topics in the aviation industry is how to use artificial intelligence (AI) in avionics. This has become important because as the number of commercial aircraft in our skies continues to increase dramatically, and the separation between aircraft decreases, this is placing a greater workload on aircraft pilots.

Also, in the defense sector, sixth-generation military fast jets are being developed which will be capable of operating in an autonomous mode.

These trends point toward the need for increased intelligence of automated systems, to reduce the workload of the pilot (or even replace the pilot) by analyzing information and making decisions, rather than presenting it to the pilot for them to make a decision – this requirement will drive the adoption of AI/ML in the cockpit.

AI in the aviation market is growing at around a 46% compound annual growth rate (CAGR). And while virtual assistants currently dominate the AI landscape in aviation, there’s more to the story than chatbots on a smartphone app or IFE screen.

The Internet of Things and devices like inflight sensors are giving AI systems more and more data to work with. And airlines are already using AI to analyze that data for things like predictive maintenance scheduling to optimizing fuel emissions.

Like all technology, avionics is constantly evolving. One of the more interesting developments is the creation of the electric hybrid aircraft, an aircraft with a hybrid electric powertrain, as the energy density of lithium-ion batteries is much lower than aviation fuel, it effectively increases the range compared to pure electric aircraft.

In 2018 there were something like 30 electric hybrid aircraft projects underway with a target date of 2032 for short-haul hybrid-electric airliners.

There’s also a plethora of more down to earth advancements in avionics technology. Current research and development in avionics and controls is expected to result in operational solutions to many of the problems anticipated because of air traffic growth.
