Nachtrag: Als ich mir jetzt noch weitere Online-Grundschulen angeschaut habe, habe ich eine gefunden, die teilweise eine unterschiedliche Meinung dazu hat.

Commission Regulation (EU) 1178/2011 as amended, Annex I, Appendix 1 (Crediting of theoretical knowledge), paragraph 3.1 requires that a licence in another category should actually be held. An applicant who has completed all the ATPL examinations for another aircraft category, whilst those examinations are still within their validity period, is covered by FCL.035 (b)(4), which refers in turn to FCL.025(c), so a CPL(H)IR holder with valid ATPL theory credits can now bridge to ATPL(A) and vice versa. The ATO must be approved specifically to deliver the bridge course and the course must comply with requirements for approved training such as at least 10% of course time being in the classroom.

Das heißt, CPL(A)/IR mit ATPL(A)-Theorie sollte für ATPL(H) Bridge ausreichen, wobei CPL(A) man schon haben muss, allein die Theorie geht doch nicht. Keine Ahnung wer hier in diese Rechtsjungel recht hat, und was geht, und was nicht geht.
