hard landing limit ???
I belive most airlines today use 600ft/min or 2G as their hard landing limit on their aircraft.If remember correct Scandinavian use this for their entire fleet.But at what sink rates is it likely that some sort of damage will occur,like gear damage or bent stringers.In the BA038 incident, I been told that the gear would have withstand the 1300 ft/min impact if it wasn,t digging into the grass.In a A320 tailscrape landing with a sink rate of 800 ft/min the engineers fould no structural damage except for the scrape damage.There are several videos on youtube were the sink rate has to be well over 600 ft/min as for example and awful landing of a 757 at Manchester.I also asking if a Widebody like 767 or 777 will withstand higher sink rates at touchdown because of it,s longer legs than for example a 737 or MD80? Someone with more knowledge please comment.
