Is there gono be any demand for avionics engineers in aviation
Yes given today's experience, the demand for me to respond to 3 logbook write ups distracted me from my internet surfing 3 times.
Little humor, I have recieved about 4-6 weeks continual training that applies to my fleet as a avionics engineer in the usa, not counting the online and on the job recurrent testing I recieve.
To your question, my airline operates aircraft developed from the 60's to the new century.
Being in an avionics department myself MGT understands that our department will be responsible for the majority of our newer fleet for the most part. It is the leading edge of aircraft maintenance.
But the nuts and bolts requirement of these machines is someting that will never go away.
Practical experience with any machine is and will allways be an asset.
