Having browsed through IRAS website I can see what Cargojock is refering to. He assumes that we are Non residents. Well, that's not correct.
"What is meant by a Resident Individual?
A Singapore citizen is a tax resident in Singapore if he normally resides in Singapore except for temporary absences that are consistent with the claim to be a resident.
A foreigner will be regarded as resident in Singapore if he was physically present or exercising an employment in Singapore for 183 days or more during the year preceding the year of assessment in a capacity other than that of a director of a company."

So, as employed by SIA Cargo you are considered a resident for tax purposes and thus can apply the NOR scheme.
Even if you wouldn't apply for the NOR scheme the taxes are reasonable. Per diem is not taxed but everything else.
As a captain you make about 250.000 a year. Deduct the per diem (30.000) and you are taxed for 220.000.
On the first 160.000 you pay 16.050 and on the next 70.000 you pay 18%. 16.050+12.600=28.650 which is not more than 11.5 % of the total package.
You can make your own calculations:
