INCORRECT!
Since 1 Apr 17, all Officer Aircrew receive their first Tier 1 RRP(F) some 6 years after starting Flying Training - regardless of the type they end up on. However, to get onto Tier 2 RRP(F) then that is 6 years after completion of OCU which is different for all as each OCU differs in length and the amount of time you take to get there. So, everyone now gets RRP(F) at roughly the same time in their cohort, but the jump to Tier 2 differs for everyone.
There is a review on RRP(F) and PAS for AFPRB 2022 - they are 5 yearly reviews, with the last one being AFPRB 2017 when the latest scheme came in.
