Thanks for your reply.
I am well aware of the principles involved here and partly based my answer on the limits you mention in the AFM of the Arrow i fly. However what i am looking for is a clear and unambiguous explanation of the method and principles required to answer that examination question.
Once again thank you for taking the trouble to post a reply but if your explanation does fully answer my question then I am afraid I don't fully follow it and would you be good enough to rephrase your explanation so I can have another crack at understanding it.
Meanwhile anyone else care to have a go?
Am I just being thick?
