Please could someone describe in simple terms what I should look for outside the window in a turn to the left? E.g. should the engine cowling be visible and if so should it be on, above or below the horizon? Is the cowling even the point of reference?
In simple terms? -> Do not, repeat, do not concentrate to actively "look" at any reference. If you do, you focus on one single spot, but you have to control a bunch of flying balls. Look outside and let your intuition do the rest while rapid scanning bank and vario. If you concentrate, you get too low. Get your brain to use the butt-AHRS connected brain-autopilot ;-).
