EIR : En route Instrument Rating
The privileges of the holder of an en route instrument rating (EIR) are to conduct flights by day under IFR in the en route phase of flight, with an aeroplane for which a class or type rating is held. It is the very first step towards the “complete” Instrument rating.
CB-IR(A) : Competency Based Training IR
This training is designed for pilots that already acquired an IFR experience. The practical training part is relatively short, and enables candidates to reach the “complete” Instrument Rating.
The EIR and CB-IR(A) theoretical trainings are both a 80 hours course. The theoretical certificate is valid for both trainings.
These specific trainings were created by the EASA as part of a process simplification and to enhance flight safety.
The training provided by the Institut MERMOZ only concerns the theoretical part of such ratings. A practical training is to be made at an aeroclub or a dedicated ATO.
