It sounds like the kind of problem that blockchains were invented to prevent. Important systems should not blindly replicate data, they should validate it.
This is the opposite of a blockchain in that there are centralized, trusted authorities (FAA, EASA) distributing this info.
Ok so it wouldn't be a public blockchain. The point is that when you replicate data you reject it if it doesn't conform to some ruleset. That way data that would break the system fails to replicate, and the scope of the problem is limited to whoever (or whatever) entered the bad data.
Data validation is a basic expectation in many technology stacks. I don't understand why blockchain would be uniquely positioned to resolve this problem.
