This is the complete set of 12 modules required for the EASA Part 66 B2 Avionics certification.Each module in this series has been approved by Civil Aviation Authorities around the world for Part 147 schools within those countries. Each is fully compliant, at the required B2 levels, and fully aligned with appendix 1 of Part 66.EASA B2 is the world's most sought-after and respected avionics certification. Any major employer, anywhere in the world, will recognize both the license and the knowledge and skills which it represents. For those interested in pursuing this technical aerospace career, there is no better path.A part of this reason is that B2 does not limit itself to just the electronics, communications, and navigation systems that are typically thought of as the extent of an avionics curriculum. It includes the entire aircraft system. You may ask why an avionics engineer needs to know about hydraulic actuators or landing gear construction. The answer is that in today's aircraft, every system is connected to every other and nearly every system has some sort of electronic interface. Today, even landing gear systems are computerized, as is the simple refueling of aircraft on the ground. Thus if you are to consider and diagnose the electronic functions of gear retraction, you need to know the basic physical operation of the gear itself. This is the difference and the reason for the high degree of respect for the license holder.
