HOW TO GET INTO
AVIONICS
Ever wondered how to get into Avionics? That’s short for Aviation
Electronics, a field that can be very challenging and satisfying.
This article looks at the work of a typical avionics maintenance
engineer and tells you how to proceed if you want a career in this
area.

O
utside my window the engine shut down. It had
been running for barely a minute. Curious, I walked
onto the tarmac to see what the problem was. The
pilot looked at me with the slightly bewildered gaze of
someone whose detailed planning has suddenly become
worthless.
“The radios don’t work,” he said, without any emotion.
“I can hear, but no-one’s responding to my calls.” It was the
same on both the VHF radios, he told me, and he hadn’t
tried the HF yet.
I started checking the standard causes. First, I gave
his microphone plug a firm push to make sure it was in
properly. “Click”. Ah, that might be it. I flicked the power
back on and called the control tower. No worries. I tried
the second VHF radio. That’s good too.

Thanking me profusely, the pilot said it was a good
thing, because he had left his lunch box in his car and he
would have left without it.
I went back inside, shaking my head. Just another minor occurrence in another very busy day in the life of an
Avionics maintenance engineer.
Avionics is an abbreviation of “Aviation Electronics”. In
the aircraft maintenance industry, an Aircraft Maintenance
Engineer (AME) in avionics looks after all the electrical,
instrument and radio systems. This may include installing, maintaining, troubleshooting and repairing avionics
systems and components.
If you want to get into avionics, you need to know which
avenues to try. Do you want to cut your teeth on the big
stuff? Are you strictly a hi-tech person? Are you willing

to work your way up from the bottom? I hope this article
will help answer these questions.
First, let’s introduce the three main branches of Aviation:
Military
The Army, Airforce and Navy provide excellent training
in Avionics. You can join from 17 to 48 years old. You will
be trained initially in Wagga Wagga, NSW, then on-the-job
in Oakey, Qld. The training gives you the same qualifications as a civilian course.
After getting your trade you will be posted to a base
in a location such as Townsville or Darwin. Your initial
enlistment will be for six years.
In the military, your job description will be broader than
most civilian aviation jobs. In addition to the standard
work on aircraft you will learn to service the ground and
test equipment while also being a soldier.
Pros: Consistently high quality training. A system that
gives you room for advancement. Respect from the industry.
Cons: Military experience does not automatically transfer to an avionics licence in “civvy street.” While your
training itself is recognised, it can be very difficult to get
any official recognition for your experience.
The basic reason for this is that military aircraft are not
on the civil register. Therefore the Civil Aviation Safety
Authority (Australia’s aviation regulatory body, generally
known as “CASA”), does not have any authority over
military aircraft nor the work done on them.
At the same time, CASA is responsible for issuing avionics licences in civil aviation.

I should explain that: without a CASA licence, you can
work on civil aircraft but you won’t get paid very much.
People with military experience outside of CASA’s authority find that their experience may not count towards
a licence.
Some of the military trained people I know have had frustrating experiences trying to get civilian licences without
effectively going back to the end of their apprenticeships.
But it can be done and once you go through the process
you should find that the industry generally accepts and
respects military experience.

Airlines
This is the “heavy metal” side of aviation. Airlines fly
anything from 19 seaters and smaller to the massive Boeing
747-400 series and the planned full length double-decker
Airbus A380.
In the airlines you will generally work on advanced,
complex avionics systems built for reliability.
You may not realise that there are several significant
airlines in Australia; not just Qantas and Virgin Blue. The
regional and subsidiary airline market with 30 to 100-seat
aircraft is seen as the growth sector within the airline
industry worldwide.
If you want to fly between, say, Albury and Canberra,
or Brisbane and Rockhampton, you could book a ticket
through Qantas but you would actually fly on one of Qantas’s subsidiary airlines such as Airlink, Eastern Australia

(and I mean actually work on them), do yourself a favor
and do not put a degree at the top of your list of options.
That leaves us with Apprenticeships. Apprenticeships
have two outstanding advantages:
1. You get paid while you learn.
2. You work as you learn, so you get to touch, break,
smell, see, repair and play with the things you are learning
about. When you come out of an apprenticeship you are
fully ready to do the work.
Perhaps I should introduce myself. I am a fourth year
apprentice in General Aviation. I work on mail planes,
charter planes, trainers, small freighters, some small
regional airliners and the Royal Flying Doctor Service
aircraft. I install, maintain and repair all sorts of electrical,
instrument and radio systems and components.
When you look at apprenticeships, it’s worth thinking
about the differences between the airlines and General
Aviation.
In the airlines you will work on more advanced avionics
in larger aircraft. The large airlines train you to work in a
specific area: Line Maintenance, Heavy Maintenance or
Component Overhaul.
Line Maintenance means “turnaround” checks and
trying to quickly solve problems that have recently come
up. This usually involves “box swapping” until you find
the box that is faulty and then send it away for repair.
Heavy maintenance means checking and repairing avionics systems while the aircraft is in the hangar for several
days or weeks for a major routine inspection. This is also
a box swapping job, as well as checking and repairing the
several kilometres of wiring running all over the aircraft.
Component Overhaul is the benchwork side of aviation:
testing and repairing the “boxes” – generators, instruments, etc, that have been removed by the line or heavy
maintenance techs. The bench techs may overhaul electric
motors, repair and calibrate instruments or test and repair
electronics to board or component level.
The great thing about General Aviation is that you can
do it all!
I spend about 50% of my time doing “line maintenance”
(including 100 hourly checks), about 30% doing “heavy
maintenance” such as modifying systems, installing new
equipment and chasing faults that have not been solved
General Aviation
GA is the “everything else” of civil aviation. This includes private owners, charter operators, corporate aircraft
and some freighters.
The majority of GA is single-piston- engine aircraft;
some new, some old. At the glamour end you have twin-jet
aircraft from tiny six-seaters to multi-office-and-boardroom jets designed for productive long-haul flights.
So how do you get into Civilian Avionics? There are
two main approaches:
1. An apprenticeship.
2. Tertiary study.
Tertiary study probably sounds like a great idea. It is,
as long as you keep in mind that people with degrees
generally don’t get to work on aircraft.
For example, you could do a Bachelor of Engineering
in Aerospace Avionics at Queensland University of Technology. This course “...prepares students for careers in the
expanding field of aircraft and spacecraft instrumentation
and in associated ground equipment.”
You would find that the course is quite deep mathematically and also covers management considerations. By
the end of the course you will know more about Avionics
than the best tradesman.
But with only three months of work experience you
probably won’t be able to remove a gyroscopic instrument
from a Cessna single without breaking something.
Compare that to a certificate IV in Aeroskills (Avionics)
at Kangan Batman TAFE, also known as the trade course.
It prepares students for “...employment with international and domestic airlines, in aircraft production and
refurbishment, and corporate and general aviation.”
This course is light on theory compared to the degree
(though you still learn a lot). Students will generally be
working in the industry for about eight or nine months
per year and will be fully ready to work as Aircraft Maintenance Engineers the day they finish.
If you want to get into design then yes, get a Bachelor of
Engineering, or perhaps an Advanced Diploma in Avionics. But if you want to work on aircraft avionics systems

by box swapping and about 20% of my time doing “component overhaul” in our radio workshop.
Practically every GA outfit does line and heavy and a
large percentage also do component overhaul.
In the airlines you may work on three or four different
aircraft types, or possibly specialise in only one or two,
for example, Boeing 737-300 and 737-400.
In GA, you will work on more types than you can
remember. A sample of my own list is: Cessna 172, 182,
206, 207, 210, 402, 404, Beech Bonanza, Baron, Piper
Seneca, Cherokee, Lance, Navajo, Chieftain, Shrike Aero
Commander, Parten-avia (all single and twin piston engine
aircraft, up to ten seats), plus Cessna 208B Grand Caravan,
Pilatus PC12, Beech Kingair 200, Fairchild Metro 23, Embraer Brasilia (all single and twin turboprop aircraft from
10 to 30 seats), plus Robinson R22, R44, Bell 206 Jetranger
(helicopters). These are just the ones I had worked on at
least a few times within my first two years of avionics.
Any work that is done on an aircraft or its components
must be certified. To certify work you must have an Aircraft Maintenance Engineer’s Licence. These licences are
issued by CASA.
How to get a licence is another story altogether. For now,
you should know that only a select few in the airlines
ever get a CASA licence. In General Aviation almost the
reverse is true, with nearly everyone encouraged to get at
least one licence.
Having or not having a CASA licence is one of the biggest single factors effecting your income in civil aircraft
maintenance.
In the airlines, unlicenced workers are paid more than
in GA. The basic reasons are that the aircraft are in a different legal classification because they carry fare-paying
passengers on regular routes and they are over 5,700kg
which puts them in a different category for CASA licences.
An airline apprentice generally has a higher base wage
than a GA apprentice. Table 1 shows the wages for both
Qantas and GA apprentices.
When you finish your apprenticeship with Qantas your
wage would be about $610.00 per week if you don’t work
on aircraft and about $640.00 per week if you do.
It is very important to realise that most of Qantas’s
finishing apprentices will not work on aircraft: they do
component overhaul in workshops.
If you do component overhaul it is unlikely that you
will ever get a CASA licence. Qantas only fills licenced
positions as they become vacant and they choose people
based on performance and qualifications.
Qantas also offers a Graduate Trainee Program so you can
follow your apprenticeship with an engineering degree.
For those who get neither a licence nor a degree, your
prospects are to progress through the Qantas ranks to
Maintenance Supervisor or a job in management. Alternatively you could move “sideways” into another related
industry such as industrial motor overhaul, consumer
electronics, etc.
On the other hand, when you finish your apprenticeship
in General Aviation your base wage would be about $480.00
per week (minimum).
The major and very important difference is that you will
almost certainly be very close to getting your first CASA
licence. All it requires is some aptitude and effort.
Once you have your first licence your wage will jump to
around $530.00, depending on which licence it is. Within a
year of your apprenticeship ending, if you put in the effort,
you could have Electrical, Instrument and Radio licences
in multiple categories. This would set your minimum wage
around $750.00 per week. Depending on which licences
you have, you could be highly sought after.
If all you want is the money then you can get certain
hard-to-find licences (certain helicopters, or the latest
bizjets, for example.) Typical wages in this niche of GA
are around $50,000 to $65,000 per year in Australia and
possibly that much in US dollars if you are willing to work
in God-forsaken countries of the world at all hours.
Airlines generally advertise their apprenticeships in
major newspapers. However, if you really want to get an

airline apprenticeship then you should contact every airline you can think of, get their application forms, and apply.
Remember to contact every regional and subsidiary
airline that you can, not just Qantas.
During my apprenticeship I studied with two Ansett
avionics apprentices. The word on the street was that about
2,000 people applied for Ansett apprenticeships that year.
About 60 were taken. Of those 60, only two were put on
as avionics apprentices. That’s two out of two thousand
applicants.
It is only fair that I tell you at the time Ansett ceased
operations, both those apprentices felt that they would
most likely end up in component overhaul, even though
they both wanted to do line maintenance and they were
entirely capable of it.
My best advice for getting into the airlines is to keep
trying, be proactive, and make sure you always show them
that you really want to work for them.
By proactive I mean you should try to make your own

opportunities: don’t just wait for a newspaper advert to

you are told there is nothing available. Be prepared for a
lot of “No” answers and also be prepared to keep trying
for every opening you see.
There is no set procedure for getting into General Aviation. Most of the avionics workshops are genuine small
businesses with around two to ten employees. The business
owners and workshop managers are flesh-and-blood people with concerns about the fickle nature of the aviation
industry. Some of them may have been laid off by various
airlines up to three or four times over their careers.
In this setting you will understand that some GA avionics businesses may consider putting on an apprentice
for several months or even years without ever taking the
step of advertising for one.
If you can find one of these businesses and show that
you are both able and interested, chances are you will
get a week’s work experience with a view to becoming
an apprentice.
I personally decided to seriously try for an apprenticeship in October 1998. I wrote a letter, included written
references from my employer at the time (a mobile phone
shop) and my previous employer (a Retravision store).
I included all my school results, science and maths
competition results and details of an unrelated qualification from my retail work. I emphasised my strong maths
and science background and the positive comments of
my previous employers. I sent all of this to an Avionics
workshop in Mackay that had advertised for an Avionics
apprentice.
I didn’t get the apprenticeship.
Still enthusiastic, I rang another organisation that I
knew had avionics engineers. They told me to send my
information but there was not really anything available. I
sent them my package.
A week later, they sent the same information to a related
company in Alice Springs. After some discussions they
decided to take me on, provided I worked in the hangar for
a year before starting on Avionics. Now I am in my fourth
year and I should be able to get several CASA licences
as soon as my apprenticeship finishes. So my advice for
getting into General Aviation is really the same as for the
airlines, only there are a lot more places to try.
Keep trying, be proactive, show your enthusiasm. Be
prepared to do a week of work experience as part of the
process. My only word of caution is that you must make
sure you know what you are being offered before you
accept anything.
With such diversity in GA there is no guarantee that your
prospective employer will help you get CASA licences, or
that you will work on any more than one or two aircraft
types. It is in your interests to know what sort of work you
will do and how far the employer will encourage you to
go, right from the start.
My last bit of advice is for older people who want to
work with avionics but cannot live on apprentice wages.
Remember that all the GA wages I have quoted are minimum wages, set out in the Aircraft Engineers (General
Aviation) award.
As a mature-aged person your job is to convince a potential employer that it’s worth taking you on instead of
a 17-year-old. Part of taking you on is to pay reasonable
adult wages. The main thing is to be (surprise, surprise)
proactive and positive. List all the reasons why you are
better, convince yourself, then set out contacting every
place you can.
It’s also worth thinking “outside the box”. At the moment
it is still possible to gain your CASA licences without
doing an apprenticeship.
You need to pass all your exams and fulfil the experience requirements but it’s possible to do your experience
as a trades assistant or (really outside the box now) an
accountant or taxi driver who works on aircraft 20 hours
a week, etc.
Please take me seriously when I say that this door
is almost closed now. New legislation currently being
introduced will effectively make it impossible to sit the
licencing exams without attending an approved course.
So if you want to get into Avionics without doing an apprenticeship, DO IT NOW!
I hope that’s enough to get you started. Anyone who likes
aircraft and enjoys electronics would agree that Avionics
is the greatest industry in the world.
Keep trying and maybe we’ll meet at a trade fair or in
SC
the tail of an aircraft one day.
