Hi Scroggs,
I can very well understand your doubts, as quality comparisons are pretty difficult in this business, because there simply is the problem of comparing i.e. the experience of two instructor pilots or the quality of the theory training.
So this is what I'm intending to do: I have one partner/friend who is an expert in financial things and one who is airline pilot. Together we worked out criteria to take a deeper look into different trainings offered, down to a level where we're planning to evaluate the place where the practical training is conducted. This is to compare traffic density (preparation for real life) and the near-by offered facilities, i.e. the number of available training airports with IFR Approaches (variety). Moreover we would like to see, if there are any sponsorships with airlines or if the graduate has better chances with his applications, just because of a more airline related, standardized training.
So hopefully, at the end we will not have a ranking, but an objective overview of ways, how all those schools lead their students to the ATP License.
Hope I could answer your questions satisfyingly! Would really like to get more of your opinions or some information on where you completed your training and which school you think would be interesting to take a look at!
Best regards!
