HI, PRUNERS
A hard landing is defined as a landing with a vertical acceleration of more than 2.6 g at the center of gravity or:
-a vertical speed (v/s) of more than 600 ft/min.
An overweight landin is defined as a landing at more tha the maximum landing weight with a vertical acceleration of more then 1.7 g at center of gravity or:
-a vertical speed (v/s) of more then 360 ft/min.
On A-320 if the aircraft has DMU/FDIMU with an enhanced load report 15, do the "inspection after hard/overweight landing for aircraft with enhanced DMU/FDIMU load repot 15".
It is responsability of the flight cr
ew to make a report if THEY THINK THERE WAS A HARD/OVERWEIGHT LANDING.
I hope this helps.
toby.
