CPL: Principles of flight questions with correct answers

What are the forces acting in a steady climb - correct answer Rearward component of weight, W2, weight, lift, thrust, and drag Can you be in equilibrium in a climb - correct answer Yes, provided your rate of climb is constant and you are not turning If you engine is not altitude boosted, if density altitude is increased what will happen to Power Available (PA) - correct answer Decrease What happens to the power required (PR) curve in a increase in density altitude - correct answer Moves up and to the right along the tangent Define service ceiling - correct answer If the ROC reduces to 100 FPM Define absolute ceiling - correct answer When ROC reaches zero Where would you find best Vx (angle of climb) on a EP (excess power) graph - correct answer Where the tangent meets the excess power curve Where is Vy (best ROC) found on a EP (excess power) graph - correct answer At the peak of the excess power available curve
