Is it true that, under the FAA AC, an operator and crew have to certified for each RNP SAAAR approach to be flown. If so, this will be a great burden on biz aviation and non-airlines.
No, the burden is on validating each approach in the database. An airline might have only 30 RNP AR IAPs in their ops specs, and they have the expertise in-house to keep precise track of those database entries.
The biz aviation guy wants to be authorized on all of them so he has to buy Honeywell or Jeppesen's database validation service.
But, operationally, once the crew has finished their quota of practice RNP AR IAPs, they are good to fly them anywhere, with the database caveat. The crew cannot validate the database in the cockpit. The procedure is much more complex than merely going through the legs page.
