While Cat3c is a new ATO and from some well known names in the industry, let's not lose sight of the fact that nobody has actually completed their ATPL course.
Really? They're starting their first ATPL course in February 2018 and nobody has completed one with them yet...and here's me thinking time travel was possible
In fact, they've got many decades of experience within the team, have been delivering non-approved supplemental training for over three years with a very high success rate, and have gone into the approved training organisation market in response to customer demand.
In any case, time will tell.
