The disc is tilted further forward but the increased download on the horizontal tail surface as speed increases maintains the fuselage in approximately the same attitude.
BONG!
Wrong.
In the 206 there are distinct attitudes for 40, 60, 90 or 110 kt. The attitude is substantially constant for a given speed, whether level, climbing or descending. I can fly to within 5kt and level, with the ASI covered up, simply by selecting a known power and a known attitude.
Power plus attitude = performance.
That equation cannot work if the attitude is always the same no matter what speed you fly.
