You hit the nail on the head Denti, if it is part of ones early training to check such vital things as cabin diff/cabin alt out of cardinal altitudes eary in ones training then it becomes part of ones personel SOPs regardless of aircraft type, its with utter dismay I have recently been given a glimpse of what pases for training at some of our "Puppy Farms" which "train" of shore students in Canada, , if it aint written down, it doesnt get checked, and if they miss a line the end result is sometimes very expensive, two gear ups WITH an instructor in the right seat!Think I might keep our little aircraft in retirment, might be a less stessfull way of flying.
