If a person is an airline cadet, and his career path is directly to the flight seat of a commercial jet, then the time spent bashing 'round in a spam-can is most likely counter-productive...having to learn the aerodynamics of light propellor planes, then having to relearn the aero's of jets is a waste of time, why not just start in the jet and be done with it...light planes teach airmanship...airliners do not require it anymore (apparently) many many hours of flying light aircraft does not necessarily generate good experience, it may in fact generate bad habits that have to be undone at the jet level, and may in worst-case scenarios, render an applicant unsuitable for airline training...food for thought
