I am in my first 47 hours of PPL training flying PA-28-161. My instructor says my stick and rudder skills are pretty good, I do good landings and engine out procedures but there are other areas where I consistently fall behind like power off stalls, class D comms, work in the pattern where I have to listen to ATC, repeat back and maintain the flight. I just feel I don't fully control the things around me. My instructor tells me I make good decisions (go around, 180 turn back home when entering IMC, etc) but we both acknowledge my execution lags. As soon as I focus on comms I am late on my first downwind landing step. The other day I forgot to retract flaps after soft field take off, being preoccupied with keeping my Vy. Or when I messed up controls during forward slip. I feel this is because I can't effectively multitask and ultimately staying ahead of the airplane. Are good pilots true multitaskers? How can I improve and get better at this?
