Trying to wrap my head around all that info. What is CBIR?
Competency Based Modular IR
In years gone by we had what was known as the unapproved IR where a pilot with a specific level of experience could do just enough training to pass the IR Skill Test. The JAA did away with that and invented the 55 hour IR Course to replace the 40 hour approved course. Despite the additional 15 hours there were less first time passes than before. This also coincided with the introduction of FNPTs and less training was conducted in aeroplanes.
The CBMIR allows you to obtain an IR with the minim ICAO requirement of 40 hours and may include unapproved training.
