I'm happy to ask stupid questions, I agree, it IS the way to learn and I am willing to (and do) with my pilot friends and the guys in the club who I know will give me a friendly answer! Its just that i'm a little more circumspect in using this forum than I was after reading some comments not only only my post, but others too.
Anyway, don't worry if some sessions in the circuit are poorer than others, I have had days where I had some absolute nightmares in the morning where I seem to have forgotten everything...and then the afternoon session or others where everything clicks and I go solo and wonder how I ever had any problems...
I do find that if there is a lot of traffic in teh circuit and my RT has to be good, then sometimes I find I have lost 100ft or am too far away from the runway on downwind leg, or i don't turn finals abeam the 400ft mark etc. Just like I found with learning to drive...you get one thing right and then something else goes pear shaped!
I'm now learning low level and glide circuits - just to confuse even more!
