S76Heavy - Try JAR-39's ACJ on sufficiency of corrective action, a real gem which is a damn sight better reading than an MEL! Its a question of managing risk. We could avoid risk turn the clock back to pre-Kittyhawk when the Wright Bros still made push-bikes.
I wonder what safety targets they will use for aircraft to the latest FARs/JARs? At least the old BCARs, that helicopters like the L2 and 101 had to meet did have very explicit numeric safety targets.
