Well ive not done what you are asking for but i did study aviation electronics in highschool. I probably forgotten about 60-70% or more on what i have learnt but i still remember some memorable experience i had in my school trip to a hangar just 20mins away.
I have visited a maintenance and overhaul base for a tour around the facility, visited a panasonic electronics company who specializes in in-flight entertainment. Pretty much my only school trip =p
I joined a basic airframe and electronics course by a training group called Lufthansa Technical Training where i learnt basic maintenance procedures so basic people l might think its funny i even need to go for a 6months course.
In that course, i learnt electronic wiring and wire repair standards on airbus and boeing which i have forgotten without practice.
Took an exam by my local authority on human factors and aviation legislation which i also forgot over my 2 years being conscripted.
Thats pretty much the most i have done in real world aviation. All my high school life was the closes to real world aviation i have been in touch with.
But, to spice thing up in any little way, i did apply for a job as an air traffic controller in Singapore region, real life stuff. Being invited for an aptitude and personality test that im going to be taking next tuesday.
Whether or not i have more stuff to add to this list depends on whether i get to be one xD
