Just remember that the approach minima for the IMCr are in real life exactly those of the IR. The exam and the propoganda will have you believe that 500/600ft are the absolute minimums for IMC holders, which is, in fact, bollocks. If you get a question on DH/A or MDH/A, use the 500/600 rubbish, not the truth. Stupid, but true.
That's always confused me, any chance you could point me towards the relevant legislation?
