I am taking the lessons with Ron Machado. I've been through the ground classes, and so far, I am taking the lesson on the VFR approach with the Boeing 737 at JFK, runway 4.
When I fly the downwind leg to the REEFO intersection (6 nm from the JFK vor), the instructor interrupts the lesson by saying that I left the training zone :'(. Did anyone deal with that problem, and how can it be avoided ? Seems to me that I follow the instructions, so I don't know what I'am doing wrong...

Thanks
Geoff
