The problem is the regulations. Because it is a composite airplane load
factors are more than doubled over that required for a tin and rivets job.
The Europa wing and center fuselage has demonstrated 8.5 G I understand,
Andy please correct me.
The reason for the conservative figures is the possibility of a real hot
day. Composites lose strength quicker than metal at elevated temperatures.
65 degrees C and above would be hot.
It is also worth noting that extreme cold makes some plastics brittle.
Gliders have been damaged after cold soak at extreme altitude.
