Instrument Rating

EASA CB-IR(A) theory course 

The instrument flight rating is one of the more difficult yet rewarding ratings you'll pursue during your flight training.

The theory course consists of 91 hours of studying. Of these, 19 hours are performed in the classroom and the remainder is distance learning.

Upcoming ground school dates: February 2024. 

By publishing the CB-IR (Competency Based Instrument Rating) EASA finally made the instrument rating easier to achieve for the General Aviation Segment. EASAs motivation for doing this was clear:

Easier access for GA pilots to Instrument Flying Rules (IFR) flying is considered a high-priority measure that will improve the safety and utility of GA flying.

About the rating


Both the EASA IR and EASA CB-IR training courses lead to the exact same rating, privileges (and licence entry). That means you are approved for IFR (including PBN) operations with approach minima as low as 200 fot AGL and RVR 800 meter for single pilot operations (550 meter with approved autopilot). However, if you wish to operate high performance aircraft (HPA) you will need to undertake a separate HPA-course.

Prerequisites for CB-IR course:

PPL(A) or CPL(A)

the privileges to fly at night in accordance with FCL.810, if the IR privileges will be used at night

Prior to skill-test: at least 50 hours of cross-country flight time as PIC in aeroplanes, TMGs, helicopters or airships, of which at least 10 shall be in the relevant aircraft category


    Is the course in Norwegian? 

    The CB-IR(A) course and all associated material is in English

    Is the classroom instruction a "must"? 

    Yes, according to EASA regulations, a certain portion of the CB-IR course has to be conducted by an instructor in a classroom. Due to Covid-19 there are ways of conducting some of this instruction as Virtual Classroom (MS Teams). The amount granted by the authorities are changing, but as of now a certain amount has to be physically in the classroom.

    Do I have to take the EASA exams in Norway? 

    No, you can sit the exams in any EASA member state

    Can you provide classroom instruction outside of Norway?

    Absolutely, depending on demand we are able to accommodate group of students in other parts of Europe. Contact us for more information.

    Do I need to have my PPL before signing up for the course?

    Yes, a PPL(A) or CPL(A) is a prerequisite for beginning the course. However, you do not need the 50 hours of cross-country until you sign up for your skill-test.
