Fresh CPL (Commercial Pilot License) holders typically begin their career as pilot trainees or co pilots and to reach that stage you generally need around 200 flying hours making it possible for CPL graduates to take up traineeship roles.
To become a CPL holder you must complete both theoretical and practical flight training and for the flying component the requirement is a minimum of 200 hours of flight time including a breakdown such as pilot in command time cross country flights instrument hours and night flying hours.
Putting it all together in a long, flowing sentence:
Beginners aiming for an airline or commercial pilot traineeship must first earn their CPL by completing a minimum of 200 flight hours which includes structured time such as solo command time, cross country and instrument flying as required by aviation authorities and once these hours are fulfilled the fresh CPL holder becomes eligible to start a traineeship or first officer role with airline or charter companies.
