When you compare this business model to CX/KA's, the monetary/time risk involved for the participant is much greater walking the path of HX than CX/KA. And there is no mentioning of the pay scale offered when those Jeppesen cadets graduate and (fortunately) receive a job offer by HX. Would they receive similar pay as other DESO or much lower because they are in "Pilot Training Program"? Only time will tell when someone is brave enough to take the offer and willing to share the information.
Also, I have known many pilots overseas where they pay their own flight training. But one difference between doing this in Europea/North America and doing it in Hong Kong is that there is no alternate plan of instructing once your HX dream has fallen short. General aviation is a very costly and restricted niche in this neck of the woods. So being a flight instructor may not pay off as well.
But I do agree that a new path for aspiring future pilots is always welcomed. The only catch is to read the fine print and know what you are heading into because committing yourself fully to this program.
