Hello, currently I am doing part 141 private pilot course. I have finished my ground school, and passed my written. Right now I am having trouble in getting the endorsement to do solo. Right now, I have more than 50 hours of flight, but still having struggle with landing (timing of flare), airspeed, and general multitasking inside plane. Yesterday, I was told that it was the best flight I have done by my instructor and was given a chance to fly with a head instructor to see if I am prepared to do first solo. I flew with him today, and I don’t know why, but made multiple mistakes. - airspeed - timing of flaps - high altitude from base to final - flaring timing (causing aircraft to go up and down on the runway) (These are most of them) I was told from the head instructor that while I show improvement, it is marginal. Also because I am not progressing a lot and not able to do solo, he decided that it is wise to change to part 61 due to its flexibility. he says: you worked for it for long period of time and still can’t make it. You won’t progress by stressing on solo like this. I don’t know what to do. I want to succeed in this course but not progressing (flight wise). Can I get some advise (other than giving up)?
