The Applied IF Restriction is a hangover from the National FI rating which actually ceased to exist in 1999, The only reason that the "No applied IF" remained, was simply because the CAA software was not updated in time and they could not cope with the JAA changes. That was back in 1999 and it has taken them 13 years to catch up.
The requirement for an FI to add Applied IF privileges by completing the IRI course, with credits for being an FI are no different now to those introduced in 1999!
There will be no removal of the " No Applied IF restriction, because there has never been a "No Applied IF" restriction under either JAR-FCL or EASA Part FCL. The training requirements to teach IF have remained unchanged throughout. The pre-entry requirements to undertake the training have changed.
