Crucial Knowledge's avionics courses employ the "TEK" training approach, which was developed by Darryl Hokanson for the Rockwell
Collins Joint Training Committee (JTC). The TEK approach accelerates training for both production and service center electronic
technicians and reduces the cost of training.
This approach, used now by the Rockwell Collins JTC for more than 10 years, departs
from the traditional method of training where each avionics unit was covered in it’s entirety. With the TEK approach, training time
is reduced by presenting short courses on avionics functional areas and technologies, reducing the time technicians must be away form
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.
What: Immersion training can consist of customer selected courses that total 5 days from the list
of available avionics courses (see click link below for a complete list of available courses). For example, your organization’s Avionics
Immersion Training Package might include "Phase Lock Looped Synthesizers, Theory and Troubleshooting" on Monday and Tuesday, "GPS Theory
and Overview" on Wednesday, "Radio Frequency Theory for Aviation Electronics" on Thursday, and "Digital Theory for Aviation Electronics"
on Friday (these are our four most popular and requested avionics courses). Your selected courses would be held, back-to-back, at a
special discount package price of only $1645 per student (eight students minimum) at your location.
