CBM is just another route to an EASA IR, the end product is the same!
Actually it is
three routes, depending on prior experience:
1) Part-FCL Aa 6 (a): Ab Initio Min 40 hours IF Instruction at an ATO, will require HoT Sign Off before Test.
2) Part-FCL Aa 6 (a) (i): Required Instruction dependent on prior experience, but with a Min 10 hours IF Instruction at an ATO, will require HoT Sign Off before Test.
3) Part-FCL Aa 8: Holds an ICAO IR and has min 50 hours IFR as PIC. No Instruction required. Hence no HoT Sign Off Required.
This is why I am so curious as to what approval bose-x has. Was it a 'Catch All' approval for the CB IR?
