Hey fellow pilot.
I talked to all the schools that exist in Indonesia in 2014, CFI and head of operation of one of the schools told me the law says you must have at least 250 hours of instruction given to validate your license and for insurance purposes, but the schools only consider people with 500 hours of instruction given, and that's just considering them for possible interview.
And from my friends in Indonesia I hear the operators won't accept walk in interviews. And remember the law for validating your license there is you must have at least 250 hours of time on type before they hire you and convert your license and everything. (That law only applies to planes with more than 12 sits.)
Why dont you consider Susi air? I hear guys have a lot of fun flying with them, and no need for 250 hours on type with them.
