The question does refer to the E(HI)4 CAA Edition.....SO YOU MUST REFER TO THE E(HI) 4/5 chart....(marked at the top "CAA CPL/ATPL Examinations")...and NOT the E(HI) 3/4
Be very careful, the two E(HI)4s are quite different in places...so if the question says E(HI)4 CAA Edition....it’s the E(HI)4/5!
