Oh I think this gives it away:
Horizon out-source a major part of the delivery of the programs to accredited Education providers for the academic components and accredited licenced hangars for task training.
According to the online map centamap.com the biz address "2 Tuen Hing Rd., Tuen Mun" is a public housing estate. I would suggest this is somebody who is making a commission from arranging, what are publicly available courses, into one 'programme'.
Suggest do the legwork yourself and save the commission.....
