Applicants for a CBIR who holds a BIR and have received at least 10 hours of instrument flight training at a training organisation may receive a credit for the whole practical flight training course towards a CBIR, as long as all competency-based instrument rating topics have been included in the BIR training, and assessed by the training organisation that provides the competency-based modular flying training course. This means that there is no minimum requirement of flight training for the CBIR if the BIR-holder has received at least 10 hours of instrument flight training at a training organisation, it is up to the training organisation to assess how much further training that is needed. Additional theoretical training at the training organisation is required in order to cover all the theoretical topics for the CBIR.
A holder of a BIR who has obtained at least 50 hours IFR PIC is only required to receive flight training for the purpose of extending the privileges to a minimum decision height of 200 feet. No theoretical training or theoretical examination is needed.
