The PAPR has been around for 4-5 years. It started out as you have to request it from a person. I think the FAA has done a great job at improving the automation from it's early days.
Initially, there were many well known vendors that had issues with their implementations. Thanks to PAPR reports, folks were able to work with their vendors to work through all the issues.
You can request a PAPR anytime you want. It will usually respond within the hour with data from your last flight.
