AH your posting is not entirely correct. You CAN be PIC of a public transport aircraft with a CPL, but it must not be heavier than 5700kg, which is where the ATPL requirement comes in.
EGCC 4284 I am not trying to sound patronising but the grammar of your posting is appalling. I would strongly advise you not to apply for any jobs once you obtain your licence without having had your letters proof-read by a friend. No offence meant, just good advice!!
