Myself and 2 others from our initial group of 7 passed ASC this last week. Two of us passed the AEC exam as well.
ASC was a fantastic experience, overall, even before I knew I'd passed. It's stressful and challenging, but you are exposed to some fantastic CF and civilian professionals, get to meet others with the same passion as you, and are exposed a little to the CF pilot experience. CAPSS is also really cool!
I don't have much insight, I left with pretty well the same understanding of CAPSS that I went in with. The parameters of the tests are not shared with the candidates either before or after. The staff are very tight lipped. This is probably to maintain the integrity of the test and introduce an additional element of stress to CAPSS. The simulators are quite modern and have a console on the inside very comparable to that of a Cessna 172 or any other light, single engine aircraft. They pitch, roll, and yaw, which is somewhat disconcerting on the inside when the sim quickly resets for the next maneuver. I think the most important thing to remember for your CAPSS sessions is to listen carefully to all instructions given by the machine and by the officer and follow them. Manage your stress and don't panic. CAPSS is very sensitive and a light touch is needed on both the yoke and rudders, but they'll remind you of this as you go. Cross-check! There are two flatscreen monitors in the front and left windows that display various readouts and instructions. Your performance will be graphically represented after each maneuver. Learn from your mistakes and work on them, but don't dwell. You've got to manage your stress. I chair-flew the last session (an outline is given in your study guide) the night before, just to straighten it out in my head. It was a big jump from the first 3 sessions to number 4. You are able to take breathers while in CAPSS. Use them to calm yourself and run through the instructions again.
Myself and one other had pilot licences already, but the third guy who passed didn't. There were a couple of benefits: a lighter touch, familiarity with instruments, but there were some detriments too: procedures in CAPSS are different than in a real plane, CAPSS is still more sensitive, overconfidence. You don't need experience to pass, they are clear about that. They fail pilots out regularly too, apparently.
You'll also be given a long test battery that lasts most of a morning. It is a bit grueling and includes tests for both PLT and AEC. Your outcome is used to rank you on the Merit List, but isn't the determining factor as to whether you pass ASC or not, that comes down to CAPSS. Review similar stuff to your CFAT, but expect more stress and tighter time. Most of the test isn't something you can study for directly.
They tell you whether you passed or failed right away, privately, and brief you on what to do next. For us who passed, we got to attend a presentation by the AEC's and do a tour of the IFR and VFR control tower/room. Then we were driven to a hotel in Toronto for our medicals.
The DRDC in Toronto is where the medicals are. There is less stress, because it's not longer up to your skill. The tests are all really neat! I've never seen my heart before, but I got to when they took the echo-cardiogram. All the medical staff are very professional and encouraging. We were told to treat the whole time like a job interview. They were quite clear that they could disqualify us for behavioral reasons as well as medical. While it's not official or overt, there is definitely a bit of psychological evaluation that goes on when you interact with the staff. Just be calm, honest, and let your enthusiasm show through (professionally). The doctor and med tech in charge briefed us at the end and told us whether we were likely to be awarded an Air Factor. While not official yet (a couple consults had to be made and a staff meeting is held to discuss any issues) they already have a good feel for your health. You know right away if you fit the types or not. All three of us passed and should receive our Air Factors soon.
That's all there is too it! Manage your stress, cross-check, be professional, and enjoy it!
Those were my impressions. Nothing new, I don't think, from past posts. Good luck all!
