I'm guessing its not possible w/o the req 5 passes. Cos this is under CAAS regs, not SIA's alone. They cant issue u a license if u dont have the requirements.. I dunno about any appeals though.
Actually is that rule confirmed? CAAS can issue licenses to people w/o the 5 req passes. It's just that the people who applied have qualifications that supersedes the requirements. It would seem rather silly that CAAS would refuse to grant a license to a person who have, say, 3000 PIC of a wide body aircraft but no O levels equivalent.
