Avionics
Training
The
Instructor
Darryl Hokanson has more than 44 years
of experience in the electronics/avionics field, including managing an
international training department, presenting technical training courses,
course development, field service engineering, and working as a production and
service center technician. This
experience includes 38 years of service at Rockwell Collins. In 2008 Mr. Hokanson was named to the United
Nations ICAO’s Roster of Experts for Avionics Training.
Past customers include domestic and
international airlines, avionics manufacturers, aircraft manufacturers,
aircraft engineering companies and government agencies.
Training Overview
Mr. Hokanson’s training approach was developed to speed up
training for production and service center electronic technicians and reduce
the cost of their training. This approach, used now for 13 years, departs from
the traditional method of training where each avionics unit was covered in it’s
entirety. With Hokanson’s approach,
training time is reduced by presenting short courses on avionics functional
areas and technologies, reducing the time technicians must be away from their
work stations.
For instance, most avionics units have similar synthesizers, so
the synthesizer course is designed to cover all synthesizers. Similarly, the power supply course covers
most avionics type supplies.
Using this approach, a maintenance facility can select just the
training courses they require to keep their technicians performing at maximum
efficiency. All theory and
troubleshooting courses include additional information on general
troubleshooting techniques and procedures.
Vetted
Training Courses
All avionics training courses are fully developed and all have
been vetted through presentations to both domestic and foreign students. Students have included avionics design
engineers, avionics system engineers, avionics lab technicians, avionics
production technicians, avionics instructors, avionics inspectors, program
managers, production managers, marketing staff and engineering students.
Customized Training
Our avionics courses are malleable to suit your needs and are
ideal:
·
As continuing or recurrent education
·
For presenting technology updates, and
·
For general skills development and improvement.
Mr. Hokanson’s avionics training approach provides organizations
with the opportunity to review their specific training requirements and then
design a custom training program by selectively choosing and combining only the
individual courses they require.
You can create your own “Immersion Training Program” by selecting
a series of courses and having the courses presented in sequence.
Training
location
These avionics training courses can be taught at your facility,
worldwide. The training facility is the
responsibility of the customer and must include desks or tables and chairs for
students, overhead digital projector, white board, and computer CD Reader and
MS Power Point. If desired, we can
arrange an appropriate local meeting space to conduct your training.
