THanks guys
Understood. Although if an aircraft is rated to 4G, and it spent its whole life flexing between 2G and 3G, rather than the more realistic 1G - 2G, then it is still within its designed limits and therefor should theoretically be as safe as the realistic example. Or does one have to redefine 'delta g' for this too?
Simple stuff for an engineer I guess, but for a pilot provided with only absolute limits with nothing in between the consequences are harder to forecast.
