There will be no DESO in the future, as there will be a new cadet short course offered for applicants with min. 1500 hours and ATPL. It is only slightly longer than the old DESO course. The only reason why it is called a cadet course is to save housing. This new course is planned to start beginning 2011.
More interesting is, that the idea came after looking at the huge amount of international cadet applicants which fulfill and/or exceed these minimum requirements.
Heard that the CX cadet program had close to 15000 applications since opened internationally. As long as the international cadet program attracts enough qualified applicants I can't see any reason why to hire DESO.
