“Aviation safety is achieved when the operation of aircraft poses no significant risk to aircrew, ground crew, passengers, other airspace users or to the general public over which such aircraft are flown.
In practice, “during peacetime” should be added to this. I don’t entirely agree with this, just an observation based on experience of what is permitted to enter service and reasons given for ignoring risks. My own opinion is that the purpose of most military aircraft is warfighting, so they should be fit for purpose, including safety. Others may not agree, but my view is that of someone who has to sign for that safety.
