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.
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.
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.
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.
