As Aluminium Persuader says demonstrated is not a limit which could be used against an insurance claim.
MTOW is a Limit and a proved overweight takeoff would mean a way out for the insurance.
One thing I am not sure of and no body has clarified is how realistically they come to a demonstrated figure?
I am sure its not the wind of the day the test is done as that could vary from 0 to 30 kts or above.
There must be a set procedure for arriving at a figure! My guess is its probably something along the lines I indicated in my last post but I do not know for sure?
Does anyone know how demonstrated is worked out?
