I've posted a few more details in the other thread regarding benefits.
You will work to the AOC not the CA to a maximum of 100 hours a month. The overseas based Captains work to this limit and reach it on a regular basis so expect SIA Cargo to be no different.
WILLIE......if you are 50 now by present SIA rules you will not be elligible for a command for 5 years. Another SIA rule also states that at 55 or above a command will not be offered.
