Hello
1st you need to have a sponsor ie: a company that needs to have HK ATPL pilots.
Then you can look here
Pilot Licences
note: 2.3.2 ATPL
ATPL (Aeroplane)
Normal Minimum
1,500 hours
Minimum on conversion terms
2,800 hours
after you apply they will look at your application and tell you what test you will need to take.
usually for ATPL it's
1 Air law 1 and Air law 2 (one of them is open book) sorry forgot which one.
2 Human Performance
3 Aircraft Performance general
4 Aircraft Type specific performance Test
5 english test above level 4 (not the english proficient on the back of your ATP now a real test.)
6 base training "touch n go's" in type applied for within six months with a HKCAD examiner in the type aircraft type applied for and within 28 days of a simulator check which is your instrument proficiency check. That was administered by a HKCAD approved examiner in the type of aircraft applied.
hope this helps good luck,
