Having again spoken to the powers be at JetStarAsia, I have obtained the following classifications:
1. The maximum age for all cadet civilian applicants is 32 years old. The requirement is that they must be young and fit so that the airline recoups its investment in the individual
2. There is no pre-requisite military requirement for the ACP. In fact of 400 applications for ACP, only 6 have so far been hired, all civilians, and are awaiting class dates, as follows, 5 SFC graduates and 1 STATA Flight Instructor. Interviews for future ACP will occur again a few months but no more than 6 will be hired each intake for ACP for the time being.
3. Even with the standard hiring, A320 type rating and 500 hour minimum time, the airline has plenty with much greater experience trying to get on and even then some just do not make it through the interview and / or simulator evaluation either.
The Pilot career remains highly competitive and challenging for the foreseeable future. In fact JAL has 1,800 highly experienced Pilot's looking for new jobs.
Good luck folks!
