ALPHA MEANS PROPORTIONAL OR Cl IS PROPORTIONAL 1\V^2?

IF THE ANGLE OF ATTACK IS INCREASED THEN SPEED IS DECREASED BECAUSE THE LIFT CONSTANT INCREASES BECAUSE THERE IS MORE OF A COEFFICIENT OF LIFT REQUIRED * WATTS? AND IF ANGLE OF ATTACK IS DECREASED THEN SPEED IS INCREASED? IF ALTITUDE INCREASES THE RO DECREASES AND LESS WATTS ARE GIVEN SO MORE THRUST SPEED IS REQUIRED TO GET LIFT?
