I’m having a real hard time with a few things in my pattern approach. The turn from upwind to downwind at 800ft and 350 knots. I’m turning too sharply and therefore too close to the carrier. Maintaining altitude when dropping gear and lowering flaps. My left hand turn when seeing the back of the carrier deck. I all too often sink during that turn and come in too low behind the ship. I should be about 350 ft but i usually come in at 250-300 and not “in the groove” at all.
