Its almost too early in my training to really say, but one thing is the pressure sometimes can be a lot. When the instructor is "putting you through paces" at what sometimes (but I am wrong) feels like too quickly. I mean, learning to make level banks, then climbing or descending banks, 30, 45, etc. and the procedures where I want to get it to "sit", but instead the next lesson he is trying to make me integrate them and just do it, so "now do a 360, while descending to 2200" and just before completing "now go to heading 90 and climb to 2800 ft and set to cruise", etc.
I felt like I had no mastery, not even competence, and was just forgetting everything. He said, gently, "I think you are doing good" which helped. This is not a complaint, I think he has a plan and this is part of it. I learned a LOT, which mostly is about WHAT I have to pay attention to at any given time. I noticed in all these maneuvers for example if he called for a 180 degree turn, I forgot to look at the current direction before starting, same with a 360 (only here I should be checking the visual outside for the starting point heading, AND the compass/dir gyro before commencing).
One thing I had practiced at home, carb heat during each change (on or off) was the one thing I was sure I would remember and the one thing I kept forgetting...
But the main thing, I forgot to look outside enough, concentrating too much on the instruments, and I forgot to enjoy the view as well as using it for reference. I know veteran or even students that have enough hours, this is probably second nature and not hard, but at my stage it is a LOT to concentrate on, and a little overwhelming. on the plus side, I reviewed myself afterwards and realized I was ALMOST there, but have to THINK while keeping flying, about what I need to know before commencing a maneuver. If I am going towards a heading, look also outside and see what landmark if any would be at that heading maybe, for sure if I am doing 360 deg turns, just basically think about what is going to happen.
But I am sure there will be lots more that I find difficult in the year to come.
