And anyway the AAIB's recommendation isn't for that, it's for an unlatched condition
@DavidReidUK
I think the AAIB recommendation has merit.
The notion of a Start-up lockout could work, but my point is that it further complicates the engine system, leaving an opening for unintended consequences, perhaps imperfect statement of requirements and all that. If done perfectly, of course, it's fine. But if we proliferate "fixes" like this we can add all sorts of new failure modes, and the eventual need to "fix" those too.
Just my philosophy, your mileage may vary.
