The previous Introductory course spent approx. five weeks in the classroom without seeing the simulators (as it happens the simulators are the same workstations you sit at during the lectures) so it's a little different now.
However I know there were a few comments about this, so the structure may have changed slightly.
For info, we started with 26 and during ADC1 and 2 we lost seven - two of those are working within NATS and another is working at a non-NATS airfield. So not at all bad compared to the average.
