I believe they could go to any CATS or Lasergrade testing site to take the actual written. There's at least a few of those in each city.

They need the CTP done before starting the official new hire syllabus. They can take the written at any usual testing center and must have it done before their ATP check. Could be 1-2 months after the course.

I wonder what happens if a "sponsored" applicant fails the ATP written after the money has been spent on the ATP CTP. Additionally, having to study for the ATP written and attending a Part 121 ground school at the same time would be interesting.

Can someone point out in the new reg where it is that you have to have the CTP or the written done before a 121 indoc?

I believe the written is required only prior to your ATP checkride (oral/practical) as far as the FAA is concerned. It's more of a company requirement to have it done prior ground school.

It's very simple, you take the cockpit procedures training segment of the training in the simulator. The path for airlines to do this has been laid out already, there is just minor changes to the training curriculum.

No whoever wrote that didn't do his research. The final rule clearly states the CTP must be done before the official 121 new hire syllabus. If a company is working on some sort of workaround then good luck to them, but it's an uphill battle with a clear rule.

In the Final Rule from July 2013.

Although part 121 and part 135 operators may elect to offer this training for their pilots, it would remain separate from part 121 and part 135 training requirements. Because the proposed ATP CTP is part of the basic certification requirements for an ATP certificate, air carriers who elect to offer this training would be required to provide the course to their pilots prior to beginning initial training. The FAA proposed that principal operations inspectors may approve a reduction of hours in an air carrier's initial training program based on material taught in the ATP CTP. However, because the ATP CTP requirements are basic certification requirements, these hours could not be reduced based on the contents of an air carrier's initial training program.

Where did you take your ATP CTP courses? How much did they charge you?

He didn't. You can get a R-ATP if you have 1500 hours and are 21.
