Matt,
The approval process for ATOs under direct EASA oversight is particularly contrived. FITA in Melbourne for example recently spent upwards of two years going through that process at considerable expense (6 to 7 figures).
Satellite training facilities located outside the EASA Member States need not be operated under direct EASA oversight, but are instead overseen by the competent authority responsible for the parent ATO. Andrewsfield Aviation, whose reputation is exemplary, is now acting as the parent ATO for NAC and I would therefore expect a high standard.
