That's probably true. Previously in UK all you needed under amendment 3 was POF(H) to get the CPL(H). It may well still be true, but we are researching it. Other countries, definitely Sweden, require all those exams for the CPL(H).
However, the ATPL(H) is a different story. You should have to do a set of bridging exams, but the UK CAA "do not have the faciities" for this. Our workaround is to get the CPL(H) as above then when you have the experience for the ATPL(H) claim an exemption for the IR based on your ATPL(A). The difference between the CPL(H) and ATPL(H) is essentially the IR.
The other aternative is to take all 14 exams.
