Wizofoz, maybe I had too much to drink at dinner tonight ... from my limited knowledge of aerodynamics, I thought:
the "chord" is the straight line between the leading and trailing edges of an aerofoil, while the "camber line" is the average of the cambers of the top and bottom surfaces of the aerofoil
the angle between the longitudinal axis of the fuselage and the chord is the "angle of incidence" and is distinguished from the "angle of attack" which is the angle between the chord and the relative airflow meeting the aerofoil
