Hi Taeyang, congrats on getting into RSAF!
Regarding the conversion, you would do well to go to the CAAS website to read the Air Safety Publications (regs) on conversion etc.
IIRC, you need 700 hours TT to convert, which I'm sure you'll have by then. Plus the fact that you're flying a "transport type" aircraft rather than a single engine fighter jet, you're in good shape!
