I remember discussions in one or more of the closed MAX threads, about Synthetic Airspeed, and how it could be used to supply a third airspeed reference for comparison. Well right here on the first page of the emails, we find that the technical pilots had a problem with that:
As I pointed out in the telecom today, an introduction of synthetic airspeed to the MAX would drastically alter this Critical Action Memory Item Non-Normal Checklist, If synthetic airspeed is standard as opposed to an option, it would likely jeopardize the Program directive to maintain Level B training for our customers.
The second page shows that they are actually skirting FAA oversight, by planning to hide things from them.
The doc marked Boeing Only has questions that we plan to ask the no-RCAS group about their expectations for any alerting that they felt might have helped in the events. It is Boeing Only because the answers they provide might show a significant deviation from the current RCAS design, and we don't want to indicate to the FAA that our design conflicts with pilot expectations.
How can the FAA provide oversight if Boeing is deliberately hiding things from them?
