Pistos,
All COTP applications now go thru ISS (In-Service Selection) in Borden. If you can find the CFRG DIN site, you can find all the info and reg's for ISS and COTP numbers. You can put your application forward for COTP and get a good write up in Part 5 of the application by your CO, and nail the interiew but there are OUTCAP numbers for each trade, based on the 'health' of the trade. Health of trades is defined as Green (less than 5% below PML and up) Amber (10% - 5% below PML) and Red (greater than 10% below PML). PML = Preferred Manning Level. For each FY, ISS gets PML and TES (Trained Effective Strength) numbers from each Career Manager shop that they use to calculate the OUTCAP numbers. I would have to go and check the ISS site for the newest info, but basically the OUTCAP numbers are based on the TES and PML numbers, for each trade. Follow me so far? Ok. Now, for a trade that is Green, 2% of that trade is the OUTCAP number, or the amount of people allowed out of that trade thru the various programs, excluding Officer generating ones IIRC correctly. Amber trades have a 1% OUTCAP number, and Red trades have a 0.5% OUTCAP number. It is important to note this...and is written specifically into the policies governing COTP...even if a trade is Red, that trade is NOT locked out for COTP applicants. Again, this is all on the ISS DIN site.
So...as an example, lets say Widget Tech has a PML of 1000, and a TES of 970. That would make them a Green trade (3% below PML). Green MOCs are allowed to OT out 2% of the TES...so 2% of 970 would be 19.4 people allowed to OT out.
Why is this? Because in the past, CMs did not want to loose people so they just locked their MOCs up. They can't do it anymore, but IAW what I said above, ISS does limit how many people can OT out of a trade each FY based on a formula using the MOC TES, PML and the MOC 'health'.
As for a COTP application, if you submit it, your CoC has to fwd it on to the BPSS/PSO office. They cannot stop it unless you do not meet the requirements laid out in the COTP msg itself (education, time in, if you are on C & P, etc). If you meet the prereq's, they must fwd it on, after the CO signs Part 5 of the application (where he/she gets to make his/her comments and/or recommendations). Even if you bomb the PSO interview, they are required to fwd the application to ISS. It is there that the file will/will not be selected, by a Selection Board, for the MOC(s) you are applying for COTP for that FY.
One specific requirement for AES Op that you must meet is Part III of the application, where you must do the Aircrew Part I and II medical, which is alittle more involved than a normal Part I and II, including the Cyclo eye exam. Once you pass all the medical stuff, Part III of your application has to signed off "fit potential aircrew" by the Doctor before the PSO office will even look at your file. Now, after that, your medical file will be sent to AMUB in Toronto, where it will be assessed and you will be assigned your Air Factor, which must be a 2 for AES Op. If you are applying, start your medical stuff now and get your AF asap, if your AF is not assessed at a 2, you are out of the pile regardless of anything else. As for whether or not AES Op will be accepting applicants right off the street, they aren't now, there appears to have been talk about this years ago and its not happening yet despite the fact that they are reasonably below PML (like 20%). I wouldn't hold my breath on that, but thats just me. I can tell you, that the 2008 COTP msg did allow for use of Reserve time if there was no break in service and it was continuous (ie Class B or C) time for the time in requirements of 48 months.
A good starting point for info on Remustering for Reg Force NCMs is CFAO 11-12. Basically for COTP, you have to have your QL4, 48 months of service and have a good record. Even if you are still a Pte, you can apply for COTP if you meet all the other requirements. Its all in the CFAO.

Hope that helps some...if you have a Forces account and want me to send you the links to the ISS site, let me know.
