Hmmm
Original posting was not intended to be a dig at students, rather their instructors who let the 'little habits go by'...for whatever reason.
Quality of instructor is a product of decent pilot and the quality of the FIC course and decent supervision during their first job. The latter (supervision) is rare. Good supervison, rarer still. Instructors pick up bad habits and then pass them onto their students. Hopfully these are picked up by somebody else, but I regularly check out PPLs and am more scared than when flying with a student!
