The privileges and IR training for FIs remains pretty much the same as under JAR-FCL, with the caveat of the qualifying flight time under IFR for FI/IRI.
FCL.905.FI FI — Privileges and conditions
The privileges of an FI are to conduct flight instruction for the issue, revalidation or renewal of:
(g) an IR in the appropriate aircraft category, provided that the FI has:
(1) at least 200 hours of flight time under IFR, of which up to 50 hours may be instrument ground time in an FFS, an FTD 2/3 or FNPT II;
(2) completed as a student pilot the IRI training course and has passed an assessment of competence for the IRI certificate; and
(3) in addition:
(i) for multi-engine aeroplanes, met the requirements for the issue of a CRI certificate;
(ii) for multi-engine helicopters, met the requirements for the issue of a TRI certificate;
So an FI will not need to hold a standalone IRI.
