EASA Modular

IRI/CRI Course

With an EASA Flight Instructor (FI) rating you are not able to teach for an instrument- or class rating. The next natural career development for a Flight Instructor is therefore to expand their instructor ratings to include Instrument Rating Instructor (IRI) and Class Rating Instructor (CRI) to be able to teach more advanced flight training.

Obtaining Instrument- and Class Rating Instructor (IRI/CRI) ratings will enable you to teach students that are working on their Instrument Rating (IR) and Multi-Engine (ME) ratings.
