FWIW and to the best of my recollection,
Regional Checkride. At XJT prior to 2001, training consisted of 3-5 sims and then a sim ride and then 2-3 aircraft events (includes the E145) and then a sim ride. Everything depended on how much sim time was available to the company to use. At one point an E145 was pulled off line and dedicated to pilot training. Eventually when all of the props were parked they went to all Level D E145 sims and you got I think 7 sims and a checkride.
Now at least prior to 2006 all of the sim rides were: first flight checks with easter eggs, engine start with abnormality, taxi, one abnormality during taxi, low vis takeoff, 2 180 degree 45 bank steep turns if you did one perfect the other was waived, all 3 approach to stalls and recoveries but I think if the first was within +/- 100' the other two were waived, non-precision to either a missed or balked landing and then the published missed and one turn in holding, then a hand flown ILS to a landing. Or reverse that and do the ILS to a missed and then a non-precision. Then V1 cut, single engine ILS to either a landing or missed depending on what you did before. Then windshear and no flap visual. I used to get fires on the V1 cut but they eventually stopped. No slewing and thats either 2 or 2.5 hours. Luckily it was all in IAH which has simple missed after they got rid of the 3 to 5 required level offs on every approach.
After 2004 or so once you passed the checkride you did a preparatory LOFT session just to get pilots used to doing an actual flight, it was non jeopardy but you could fail it.
The Glory Days. Back around 1999 we had pay for training. $10K for ATR/120 and $7K or $8K for the 1900D. You were not paid, reimbursed for hotels, per diem, etc until you completed your checkride. Now, back then I remember hearing that you could not fail the ride, if you did you lost the job and all but like half or $3K of the training cost. Later when I was around you could fail one ride but were let go if you fail twice. It seems like once regionals started paying for training then they were less reluctant to fire you for failing and they eventually got to where you could redo a single unsat maneuver but any more unsats or if time ran out then it was a failure. Now, these were never pink slips, just failures. I am curious if now with new hires getting SIC types if a failure is a pink slip?
My Major airline uses the AQP system and initial training has 4 series of events. The first or 100 series is 4 low level FTDs or system trainers and a progress check and then the computer oral. The next is the 200 series with 4 real FTDs with a lot of approaches and CAT II/III stuff and then a progress check.
Then the next is the 300 series which has 4 real sims and a maneuvers checkride that starts at the runway and does all of the following at some point, normal takeoff, V1 cut, RTO, visual, non-precision, engine out precision, missed approach, landing, landing engine-out, landing no flap and a takeoff and then approach windshear encounter. One of the approaches has to be hand flown. I do not believe this is a pink slip event unless you're an FO going for a PIC type then you can pink slip on the left seat maneuvers which are an RTO, taxi and visual approach. I could be wrong about the rest not being jeopardy though.
The last series is the 400 which has 4 sim sessions and a checkride (actually your type ride) and all of the events are line oriented operations. The loft is the jeopardy event, its real time gate to gate and it'll have one of any 8 events with any [U]one[U] of 20+ MELs. All selected by the computer. So life sucks if you get the one where you have to wear your mask and autothrottles are on MEL.
ATP Standards are the same for the regionals, majors or an ALL ATPs Seminole driver on one of those two day crash courses. Here is a run down: http://rgl.faa.gov/REGULATORY_AND_GUIDANCE_LIBRARY/RGADVISORYCIRCULAR.NSF/0/370f8d9f69094b8d86256a1c00709d5c/$FILE/faa-s-8081-5d.pdf
