SecureEvtol requires two-party authorization: entering diagnostic maintenance mode requires simultaneous cryptographic authentication from both the lead mechanic and the quality assurance inspector. The flight computer verifies both digital signatures against the airline's master PKI registry, eliminating single-point insider threats.
