yes, in an ideal world the 200hr guy would sweep the hangar floor, learn the business from the bottom up, sit left seat to a more experienced pilot and get some wisdom, maybe fly easy photo flights, ferry flights etc
unfortunately this is reality. insurance companies are reluctant to insure commercial pilots on anything other than an r22 with under 1,000 hours
plus, there just isnt the opportunity for every 200 hr guy to start at the bottom of the business sweeping floors etc
and... do you really think someone who has just spent 50,000+ dollars/pounds on his professional licence will be happy sweeping floors for 2 years before getting a sniff of the controls?
