The travelling public could care less about 1 and 2, they cant even be bothered to find out how long their crew have been awake for and how long they have been on duty. A hard landing (its either an overweight landing or a hard landing no such thing as a heavy landing) is a landing that experiences greater than 2 g vertical acceleration at touchdown. As BSM stated the information is immediately available to maintenance. If the hard landings I have experienced in the sim are anything to go by a hard landing will be felt through your spine. up through the neck and explode in your cranium.
